1. What Are The Short-Term Effects Of Cannabis Use?

The short-term effects of cannabis use can vary significantly from person to person, influenced by factors such as individual physiology, the specific strain of cannabis, and the method of consumption. Common short-term effects include altered sensory perception, impaired coordination, difficulty with thinking and problem-solving, and an increased heart rate.

Everyone’s experience with cannabis is unique. When using cannabis, you may encounter:

Altered Sensory Perception: Cannabis can intensify sensory experiences, making colors appear brighter, sounds more distinct, and tastes more pronounced.
Impaired Coordination: Motor skills and coordination can be significantly affected, leading to difficulties with tasks such as driving or operating machinery.
Cognitive Impairment: Short-term memory and the ability to focus can be diminished, making it challenging to perform tasks that require concentration and critical thinking.
Increased Heart Rate: THC can elevate heart rate, potentially leading to anxiety or discomfort, particularly in individuals with pre-existing heart conditions.
Relaxation: Some users feel calm and relaxed.
Anxiety: Other users might feel anxious or paranoid.
Increased Appetite: Often called “the munchies,” cannabis can stimulate appetite.

1.1 How Does Cannabis Affect Perception?

Cannabis affects perception by interacting with the brain’s endocannabinoid system, which plays a key role in regulating mood, sensory experiences, and cognitive functions. THC, the primary psychoactive compound in cannabis, binds to cannabinoid receptors in the brain, altering neuronal activity and leading to changes in how sensory information is processed.

The effects of cannabis on perception can manifest in various ways:

Visual Distortions: Users may experience altered depth perception, changes in color perception, and visual hallucinations in some cases.
Auditory Changes: Sounds may seem louder, more distinct, or distorted. Music can be experienced with greater intensity, which is why many people enjoy listening to music while using cannabis.
Time Distortion: The perception of time can be altered, with time seeming to either speed up or slow down. This distortion can affect the ability to gauge how long activities take.
Tactile Sensations: Sensations like touch and pain can be amplified or altered, leading to heightened sensitivity or, conversely, a decreased ability to perceive pain.
Altered Body Image: Some individuals report changes in their perception of their own body, such as feeling lighter or heavier than usual.

1.2 What Is The Impact Of Cannabis On Coordination?

Cannabis significantly impacts coordination due to the effects of THC on the cerebellum and basal ganglia, brain regions crucial for motor control and coordination. THC disrupts normal neuronal communication in these areas, leading to impaired motor skills, balance, and reaction time.

The impact of cannabis on coordination can manifest in several ways:

Impaired Motor Skills: Users may experience difficulty performing tasks that require fine motor skills, such as writing, typing, or using small tools.
Reduced Balance: Cannabis can affect balance and stability, increasing the risk of falls and accidents.
Slower Reaction Time: Reaction time is often significantly delayed, making activities like driving or operating machinery dangerous.
Decreased Hand-Eye Coordination: Tasks that require precise hand-eye coordination, such as sports or video games, can be more challenging.

1.3 How Does Cannabis Influence Cognitive Function?

Cannabis influences cognitive function primarily through the interaction of THC with cannabinoid receptors in the brain regions responsible for cognitive processes such as memory, attention, and executive functions. This interaction disrupts normal neuronal activity, leading to temporary cognitive impairments.

The specific ways in which cannabis affects cognitive function include:

Memory Impairment: Short-term memory is particularly vulnerable, with users often struggling to remember recent events or new information. This can affect learning and the ability to follow complex instructions.
Attention Deficits: Difficulty focusing and maintaining attention is a common effect. This can impair performance in tasks that require sustained concentration, such as reading or studying.
Impaired Executive Functions: Executive functions, including planning, decision-making, and problem-solving, can be negatively affected. Users may find it harder to think strategically or make rational choices.
Reduced Processing Speed: The speed at which information is processed can be slowed, making it more difficult to respond quickly or think on one’s feet.

2. What Are The Long-Term Risks Of Cannabis Use?

Long-term cannabis use is associated with several potential health risks, particularly when use begins during adolescence. These risks include an increased likelihood of developing cannabis use disorder, respiratory problems, cognitive impairments, and mental health issues.

2.1 What Is Cannabis Use Disorder?

Cannabis Use Disorder (CUD) is a condition characterized by the compulsive use of cannabis despite negative consequences. It is defined by a pattern of problematic cannabis use that leads to clinically significant impairment or distress. The development of CUD is influenced by a combination of factors, including genetics, environmental influences, and the frequency and intensity of cannabis use.

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), CUD is diagnosed based on the presence of at least two of the following criteria within a 12-month period:

Taking cannabis in larger amounts or for longer than intended: This involves using more cannabis than initially planned or continuing to use it over a longer period despite attempts to cut down.
Persistent desire or unsuccessful efforts to cut down or control cannabis use: The individual may have a strong desire to reduce or stop cannabis use but is unable to do so despite repeated attempts.
A great deal of time is spent in activities necessary to obtain cannabis, use cannabis, or recover from its effects: This includes spending significant time seeking out cannabis, using it, or recovering from its after-effects, which can interfere with daily responsibilities.
Craving, or a strong desire or urge to use cannabis: Cravings are intense urges to use cannabis that can be difficult to resist and often lead to continued use.
Recurrent cannabis use resulting in a failure to fulfill major role obligations at work, school, or home: Cannabis use may interfere with job performance, academic achievement, or domestic responsibilities.
Continued cannabis use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of cannabis: The individual continues to use cannabis despite knowing that it is causing problems in relationships or social interactions.
Important social, occupational, or recreational activities are given up or reduced because of cannabis use: The individual may withdraw from activities they once enjoyed in order to use cannabis.
Recurrent cannabis use in situations in which it is physically hazardous: Using cannabis in situations where it could be physically dangerous, such as driving or operating machinery.
Cannabis use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by cannabis: The individual continues to use cannabis despite knowing that it is worsening a health condition.
Tolerance, as defined by either of the following:
- A need for markedly increased amounts of cannabis to achieve intoxication or desired effect.
- A markedly diminished effect with continued use of the same amount of cannabis.
Withdrawal, as manifested by either of the following:
- The characteristic withdrawal syndrome for cannabis.
- Cannabis (or a closely related substance) is taken to relieve or avoid withdrawal symptoms.

2.2 What Are The Respiratory Problems Associated With Cannabis Use?

Respiratory problems are a significant concern associated with long-term cannabis use, particularly when cannabis is smoked. The combustion of cannabis plant material produces many of the same harmful toxins and carcinogens found in tobacco smoke, leading to damage and inflammation of the respiratory system.

The specific respiratory issues linked to long-term cannabis smoking include:

Chronic Bronchitis: Prolonged exposure to cannabis smoke can cause chronic inflammation and irritation of the bronchial tubes, leading to symptoms such as chronic cough, increased mucus production, and wheezing.
Increased Risk of Respiratory Infections: Cannabis smoke can impair the function of immune cells in the respiratory tract, making individuals more susceptible to respiratory infections like bronchitis and pneumonia.
Airway Obstruction: Long-term cannabis smoking can lead to airway obstruction, making it difficult to breathe and reducing lung capacity.
Potential for Lung Cancer: While more research is needed, some studies suggest that long-term cannabis smoking may increase the risk of lung cancer. The presence of carcinogens in cannabis smoke is a significant concern.

2.3 How Does Long-Term Cannabis Use Affect Cognitive Function?

Long-term cannabis use can have lasting effects on cognitive function, particularly when use begins during adolescence. The developing brain is more vulnerable to the neurotoxic effects of THC, the primary psychoactive compound in cannabis.

Specific cognitive impairments associated with chronic cannabis use include:

Impaired Memory: Long-term cannabis use can impair both short-term and long-term memory. Users may struggle to learn new information or recall past events.
Reduced Attention Span: Difficulty focusing and maintaining attention is a common issue. This can affect academic and professional performance.
Executive Function Deficits: Executive functions, such as planning, decision-making, and problem-solving, can be negatively affected.
Decreased Processing Speed: The speed at which information is processed can be slowed, making it more difficult to respond quickly or think on one’s feet.

2.4 What Mental Health Issues Are Linked To Cannabis Use?

Mental health issues are a significant concern associated with long-term cannabis use, particularly among individuals with pre-existing mental health conditions or a genetic predisposition to mental illness. Cannabis use has been linked to an increased risk of developing or exacerbating various mental health disorders.

Specific mental health issues associated with cannabis use include:

Anxiety Disorders: Cannabis use can trigger or worsen anxiety symptoms, including generalized anxiety, panic attacks, and social anxiety.
Depression: Some studies suggest a link between long-term cannabis use and an increased risk of depression. Cannabis can disrupt the balance of neurotransmitters in the brain, potentially contributing to depressive symptoms.
Psychosis: Cannabis use has been associated with an increased risk of psychotic disorders, such as schizophrenia, particularly among individuals with a genetic vulnerability. THC can induce psychotic symptoms, including hallucinations, delusions, and disorganized thinking.
Bipolar Disorder: Cannabis use can destabilize mood and trigger manic or depressive episodes in individuals with bipolar disorder.

3. How Does Cannabis Affect Young People’s Health?

Cannabis can affect the same biological system in the brain that is responsible for brain development.

Youth and young adults are more likely to experience harms from cannabis because their brains develop until about age 25. The earlier you start consuming cannabis, the more harm it can do.

3.1 How Does Cannabis Impact Brain Development In Adolescents?

Cannabis significantly impacts brain development in adolescents because the brain continues to mature until around age 25. THC, the primary psychoactive compound in cannabis, disrupts the normal development of brain regions responsible for cognitive functions, emotional regulation, and decision-making.

Specific ways in which cannabis affects brain development include:

Reduced Gray Matter Volume: Studies have shown that chronic cannabis use during adolescence is associated with reduced gray matter volume in brain regions such as the hippocampus, prefrontal cortex, and amygdala. These areas are critical for memory, executive functions, and emotional processing.
Altered White Matter Integrity: Cannabis use can disrupt the development of white matter, which is essential for efficient communication between different brain regions. This can lead to cognitive deficits and impaired neural connectivity.
Disrupted Dopamine System: THC can interfere with the normal functioning of the dopamine system, which plays a key role in reward, motivation, and learning. This can increase the risk of addiction and other mental health problems.

3.2 What Are The Risks Of Early Cannabis Use On Mental Health?

Early cannabis use poses significant risks to mental health, particularly during adolescence when the brain is still developing. Starting cannabis use as a teen increases the likelihood of developing mental health problems such as anxiety, depression, and psychosis.

Specific risks of early cannabis use on mental health include:

Increased Risk of Anxiety and Depression: Early cannabis use has been linked to an increased risk of developing anxiety disorders and depression. Cannabis can disrupt the balance of neurotransmitters in the brain, potentially contributing to these conditions.
Higher Risk of Psychosis: Adolescents who use cannabis are at a higher risk of developing psychotic disorders, such as schizophrenia, especially if they have a genetic predisposition to these conditions.
Exacerbation of Existing Mental Health Conditions: Cannabis use can worsen symptoms in individuals who already have mental health conditions, making it more difficult to manage their illness.
Increased Risk of Suicidal Thoughts and Behaviors: Some studies have found a link between cannabis use and an increased risk of suicidal thoughts and behaviors, particularly among young people with mental health problems.

3.3 How Does Cannabis Affect Learning And Memory In Young People?

Cannabis can harm important aspects of thinking, like learning and memory. Stopping use can help improve these deficits. However, some of these harms may persist for months or years, or may not be fully reversible.

Specific ways in which cannabis affects learning and memory include:

Impaired Short-Term Memory: Cannabis use can impair short-term memory, making it difficult for young people to remember new information or follow complex instructions. This can affect academic performance and the ability to learn new skills.
Reduced Attention Span: Difficulty focusing and maintaining attention is a common effect of cannabis use, which can interfere with learning and academic achievement.
Impaired Executive Functions: Cannabis can negatively affect executive functions, such as planning, decision-making, and problem-solving. This can make it more difficult for young people to think strategically and make rational choices.

4. How To Lower Risks When Consuming Cannabis?

There are risks associated with cannabis use. The best way to protect your health is to avoid using cannabis or cannabis products completely.

If you still consume Cannabis, research suggests that there are ways to reduce the risks:

Use it in a safe and familiar environment and with people you trust, especially if you are inexperienced or a new user.
Delay cannabis use until the brain is fully developed. This occurs around the age of 25.
- The earlier you begin using cannabis, the higher your risk of serious health issues, including dependence and other mental health problems.
Choose a product with equal or higher amounts of CBD than THC.
- The higher the THC content of a product, the more likely you are to experience adverse effects and greater levels of impairment. CBD is known to reduce some of the effects of THC.
If you smoke cannabis, avoid inhaling deeply or holding your breath.
Limit and reduce how often you use.
- Frequent use of cannabis over a long time can contribute to mental health problems. These include dependence, anxiety, and depression.
Avoid mixing cannabis and other substances, like alcohol or drugs.
- Using cannabis at the same time as drinking alcohol and/or using other drugs can cause more severe levels of impairment and adverse effects. Other drugs include pain medications (opioids) and tranquillizers (benzodiazepines).
Avoid using cannabis and driving or operating machinery.
- After alcohol, cannabis is the drug most often linked to car accidents. Cannabis can affect your concentration, attention and coordination, and slow your reaction time. Using it and driving or operating machinery increases the risk of having an accident, which can result in serious injuries or death.
Avoid using synthetic cannabis products, which are illegal.
- Products known as synthetic cannabis (K2, spice) are not cannabis at all. These products are very different, have much stronger effects and are more dangerous. Using synthetic cannabis can lead to severe health problems, such as seizures, irregular heartbeat, hallucinations and, in rare cases, death.
Avoid cannabis completely if you are at risk for mental health problems, especially
- psychosis
- schizophrenia
- problematic substance use

4.1 What Are Safer Consumption Practices?

Safer consumption practices involve strategies to minimize the health risks associated with cannabis use. These practices focus on reducing exposure to harmful substances, managing dosage, and making informed choices about cannabis products.

The following are some key safer consumption practices:

Choose Lower THC Products: Opt for cannabis products with lower THC concentrations. THC is the primary psychoactive compound in cannabis, and higher levels are associated with an increased risk of adverse effects, such as anxiety, paranoia, and impaired cognitive function.
Consider CBD-Rich Products: Choose products with a higher CBD (cannabidiol) content relative to THC. CBD is a non-psychoactive compound that may help mitigate some of the negative effects of THC, such as anxiety and psychosis.
Avoid Smoking: Smoking cannabis involves inhaling combustion byproducts that can damage the respiratory system. Consider alternative methods of consumption, such as edibles, tinctures, or vaporizers.
Use a Vaporizer: Vaporizers heat cannabis to a temperature that releases the active compounds without burning the plant material. This reduces exposure to harmful toxins and carcinogens.
Start Low and Go Slow: When consuming cannabis, particularly edibles, start with a low dose and wait to see how it affects you before taking more. Edibles can take longer to produce effects, and it is easy to consume too much if you are not careful.
Avoid Mixing with Alcohol or Other Drugs: Combining cannabis with alcohol or other drugs can increase the risk of adverse effects and unpredictable interactions. Avoid using cannabis with other substances, especially if you are inexperienced.
Use in a Safe Environment: Consume cannabis in a safe and familiar environment where you feel comfortable and supported. Avoid using cannabis in public places or situations where you need to be alert and in control.
Stay Hydrated: Cannabis use can cause dehydration, so it is important to drink plenty of water before, during, and after consumption.
Avoid Driving or Operating Machinery: Cannabis can impair coordination, reaction time, and cognitive function, making it unsafe to drive or operate machinery. Avoid these activities after consuming cannabis.
Store Cannabis Safely: Store cannabis products in a secure location out of reach of children and pets. Use child-resistant containers to prevent accidental ingestion.
Be Aware of Interactions with Medications: Cannabis can interact with certain medications, so it is important to consult with a healthcare professional if you are taking any prescription drugs.
Limit Use: Reduce the frequency and amount of cannabis consumed. Frequent use can lead to tolerance, dependence, and an increased risk of adverse effects.

4.2 What Is The Role Of CBD In Mitigating Negative Effects?

CBD (cannabidiol) plays a significant role in mitigating some of the negative effects associated with THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis. CBD is a non-psychoactive cannabinoid that interacts with the body’s endocannabinoid system, modulating the effects of THC and potentially reducing its adverse impacts.

CBD can counteract several negative effects of THC:

Reduced Anxiety and Paranoia: THC can induce anxiety and paranoia in some individuals. CBD has anxiolytic (anxiety-reducing) properties and can help counteract these effects.
Mitigation of Psychotic Symptoms: THC can trigger psychotic symptoms in susceptible individuals. CBD has antipsychotic properties and may help reduce the risk of psychosis.
Neuroprotective Effects: CBD has neuroprotective properties and may help protect the brain from damage caused by THC.
Reduced Cognitive Impairment: THC can impair cognitive function, affecting memory, attention, and executive functions. CBD may help mitigate these cognitive deficits.

4.3 How Does Consumption Method Affect Risk?

The method of cannabis consumption significantly affects the associated health risks. Different methods involve different routes of administration and exposure to harmful substances, which can impact the respiratory system, cardiovascular system, and brain.

The primary methods of cannabis consumption include:

Smoking: Smoking cannabis involves burning the plant material and inhaling the smoke. This method is associated with significant respiratory risks due to the inhalation of combustion byproducts, such as tar, carcinogens, and particulate matter.
Vaping: Vaping involves heating cannabis to a temperature that releases the active compounds without burning the plant material. This reduces exposure to harmful toxins compared to smoking.
Edibles: Edibles are cannabis-infused foods or beverages. This method involves ingesting cannabis, which is metabolized differently than inhaled cannabis.
Tinctures: Tinctures are liquid extracts of cannabis that are typically administered under the tongue. This method allows for rapid absorption into the bloodstream without the need for inhalation.
Topicals: Topicals are cannabis-infused lotions, balms, or creams that are applied to the skin. This method is used for localized pain relief and does not produce psychoactive effects.

Each consumption method has unique risks:

Consumption Method	Risks
Smoking	Respiratory problems (chronic bronchitis, increased risk of respiratory infections), exposure to carcinogens, potential cardiovascular effects.
Vaping	Respiratory irritation, potential exposure to harmful chemicals in vape liquids, long-term respiratory effects not yet fully understood.
Edibles	Delayed onset of effects (leading to overconsumption), risk of accidental ingestion by children or pets, unpredictable absorption and metabolism, potential for intense psychoactive effects.
Tinctures	Potential for rapid absorption and intense effects, risk of accidental overconsumption, may contain alcohol.
Topicals	Limited to localized effects, minimal risk of systemic effects or psychoactive effects, potential for skin irritation or allergic reactions.

5. What Are The Effects Of Cannabis On Pregnancy And Breastfeeding?

Avoid cannabis completely if you are pregnant or breastfeeding. Substances in cannabis are transferred from the mother to child and can harm your unborn or newborn baby.

5.1 How Does Cannabis Use During Pregnancy Affect The Fetus?

Cannabis use during pregnancy poses significant risks to the developing fetus. The active compounds in cannabis, primarily THC, can cross the placenta and affect fetal brain development, potentially leading to long-term neurodevelopmental issues.

The following are specific ways in which cannabis use during pregnancy can affect the fetus:

Brain Development: THC can disrupt the normal development of the fetal brain, particularly areas responsible for cognitive functions, emotional regulation, and behavior. This can increase the risk of neurodevelopmental disorders, such as ADHD and autism spectrum disorder.
Low Birth Weight: Studies have shown that cannabis use during pregnancy is associated with an increased risk of low birth weight. Low birth weight infants are at higher risk for various health problems, including respiratory distress, feeding difficulties, and developmental delays.
Premature Birth: Cannabis use during pregnancy may increase the risk of premature birth. Premature babies are at higher risk for a range of health complications, including respiratory problems, infections, and long-term disabilities.
Stillbirth: Some studies have suggested a possible association between cannabis use during pregnancy and an increased risk of stillbirth, although more research is needed to confirm this link.

5.2 What Are The Risks Of Cannabis Use While Breastfeeding?

Cannabis use while breastfeeding poses risks to the nursing infant. THC, the primary psychoactive compound in cannabis, can be transferred through breast milk to the infant, potentially affecting brain development and causing other adverse effects.

The following are specific risks of cannabis use while breastfeeding:

THC Exposure: THC can be present in breast milk for up to six days after cannabis use. Exposure to THC can affect the infant’s brain development, potentially leading to long-term neurodevelopmental problems.
Impaired Motor Development: Some studies have suggested that infants exposed to THC through breast milk may experience impaired motor development, such as delays in crawling, walking, and other motor skills.
Cognitive Deficits: THC exposure can potentially affect the infant’s cognitive development, leading to problems with attention, learning, and memory.

6. Is Cannabis Addiction Real?

Cannabis addiction is real, although the risk of addiction is lower than it is for other substances such as tobacco, alcohol, and opioids.

Using cannabis frequently can lead to a pattern of problematic use or use disorder. This can result in dependence or addiction.

6.1 What Are The Signs Of Cannabis Addiction?

Experiencing a cannabis addiction can cause serious harm to your health, social life, school work, work and financial future

The signs of cannabis addiction, also known as Cannabis Use Disorder (CUD), can vary from person to person, but they generally involve a pattern of compulsive cannabis use despite negative consequences.

Here are some key signs to watch out for:

Tolerance: Needing to use more and more cannabis to achieve the same effects.
Withdrawal Symptoms: Experiencing unpleasant physical or psychological symptoms when trying to quit or reduce cannabis use.
Loss of Control: Using cannabis in larger amounts or for longer periods than intended.
Persistent Desire to Quit: Wanting to quit or cut down on cannabis use but being unable to do so.
Spending Excessive Time on Cannabis: Devoting a significant amount of time to obtaining, using, or recovering from the effects of cannabis.
Neglecting Responsibilities: Failing to fulfill obligations at work, school, or home due to cannabis use.
Continued Use Despite Problems: Continuing to use cannabis despite knowing that it is causing or worsening physical or psychological problems.
Giving Up Important Activities: Giving up or reducing participation in social, occupational, or recreational activities because of cannabis use.
Cravings: Experiencing intense urges or cravings for cannabis.

6.2 How Does Cannabis Dependence Develop?

Cannabis dependence develops through a complex interplay of factors, including genetic predispositions, environmental influences, and the frequency and intensity of cannabis use. Regular cannabis use can lead to changes in the brain’s reward system, making it more difficult to quit or reduce use.

Here’s a closer look at how cannabis dependence develops:

Repeated Exposure: Regular cannabis use can lead to changes in the brain’s reward system, particularly in the dopamine pathways. THC, the primary psychoactive compound in cannabis, triggers the release of dopamine, creating a sense of pleasure and reinforcement.
Tolerance: With continued cannabis use, the brain adapts to the presence of THC, requiring higher doses to achieve the same effects. This is known as tolerance.
Withdrawal Symptoms: When cannabis use is reduced or stopped, the brain can experience withdrawal symptoms, such as anxiety, irritability, insomnia, decreased appetite, and cravings. These symptoms can make it difficult to quit or reduce cannabis use.
Compulsive Use: As dependence develops, individuals may find themselves using cannabis compulsively, despite negative consequences. They may prioritize cannabis use over other important activities and responsibilities.
Loss of Control: Individuals with cannabis dependence may experience a loss of control over their cannabis use. They may want to quit or cut down but are unable to do so.

6.3 What Resources Are Available For Addiction Treatment?

Quitting is not always easy. If you are struggling with your cannabis use, you can:

discuss your cannabis use with your physician or other trusted health care provider or counsellor
reach out to organizations or groups that deal with addiction

If you or someone you know is struggling with cannabis addiction, there are many resources available to help:

Medical Professionals: Talk to your doctor or a mental health professional. They can assess your situation, provide guidance, and recommend appropriate treatment options.

Support Groups: Support groups like Marijuana Anonymous (MA) provide a safe and supportive environment for individuals to share their experiences and receive encouragement.
Online Resources: Websites like the National Institute on Drug Abuse (NIDA) and the Substance Abuse and Mental Health Services Administration (SAMHSA) offer valuable information and resources on cannabis addiction and treatment options.
Hotlines: Call the SAMHSA National Helpline at 1-800-662-HELP (4357) for confidential support and referrals to local treatment facilities.

7. What Is Cannabis Poisoning?

Accidentally consuming or consuming too much cannabis at a time can lead to temporary adverse effects, also known as cannabis poisoning. Cannabis poisoning is not generally known to be fatal. It can, however, be very unpleasant and potentially dangerous, sometimes requiring emergency medical attention and, in some cases, hospitalization. Children and pets are at greater risk of cannabis poisoning.

7.1 What Are The Symptoms Of Cannabis Poisoning?

The higher the THC content in a product, the higher the likelihood of experiencing adverse effects/poisoning, especially if you are a first-time or inexperienced user.

It is also easier to be poisoned when ingesting (eating or drinking) cannabis compared to inhaling cannabis (smoking or vaping). This is because some of these products may be confused with similar non-cannabis products. It can also take much longer to feel the effects. The result is that people consume more before they feel the full effects.

Symptoms can include:

chest pain
rapid heartbeat
nausea/vomiting
psychotic episode
respiratory depression
severe anxiety and/or panic attack

7.2 How Is Cannabis Poisoning Diagnosed?

Diagnosing cannabis poisoning typically involves a clinical assessment based on the individual’s symptoms, history of cannabis use, and a physical examination. There is no specific lab test to confirm cannabis poisoning, so diagnosis relies on ruling out other potential causes and identifying symptoms consistent with cannabis toxicity.

Here are the key steps in diagnosing cannabis poisoning:

Medical History: The healthcare provider will ask about the individual’s recent cannabis use, including the amount consumed, the method of consumption (e.g., smoking, edibles), and any other substances that may have been used concurrently.
Symptom Evaluation: The healthcare provider will assess the individual’s symptoms and look for signs consistent with cannabis poisoning, such as anxiety, paranoia, confusion, hallucinations, rapid heart rate, nausea, vomiting, and dizziness.
Physical Examination: A physical examination may be performed to assess vital signs, such as heart rate, blood pressure, and respiratory rate. The healthcare provider may also check for neurological symptoms, such as impaired coordination or altered mental status.
Ruling Out Other Causes: The healthcare provider will rule out other potential causes of the individual’s symptoms, such as other drug overdoses, infections, or underlying medical conditions.
Toxicology Screening: In some cases, a urine or blood toxicology screen may be performed to detect the presence of cannabis or other substances. However, a positive toxicology screen alone does not confirm cannabis poisoning, as cannabis can remain in the system for several days or weeks after use.

7.3 What Are The Treatment Options For Cannabis Poisoning?

Treatment for cannabis poisoning typically focuses on managing the individual’s symptoms and providing supportive care until the effects of cannabis wear off. Cannabis poisoning is rarely fatal, but it can be uncomfortable and distressing, particularly for children or inexperienced users.

Here are the primary treatment options for cannabis poisoning:

Observation and Monitoring: The individual will be closely monitored for any changes in vital signs, mental status, or respiratory function.
Symptom Management: Treatment will focus on managing the individual’s symptoms. This may include anti-anxiety medications for anxiety or panic attacks, anti-nausea medications for nausea and vomiting, and pain relievers for headache or muscle aches.
Hydration: Dehydration is a common symptom of cannabis poisoning, so intravenous fluids may be administered to restore fluid balance.
Respiratory Support: In rare cases, individuals with severe respiratory depression may require oxygen therapy or mechanical ventilation.
Activated Charcoal: If the individual has ingested cannabis (e.g., edibles) and presents to the emergency room shortly after consumption, activated charcoal may be administered to prevent absorption of the cannabis in the gastrointestinal tract.
Psychiatric Evaluation: Individuals with severe psychiatric symptoms, such as hallucinations or paranoia, may require a psychiatric evaluation and treatment.

8. Cannabis For Medical Purposes
