Understanding Cannabis Use Disorder

Cannabis (marijuana) is the most widely used illicit substance in Canada. While often perceived as harmless,
regular cannabis use can lead to Cannabis Use Disorder (CUD)—a recognized substance use disorder
characterized by problematic use, tolerance, withdrawal symptoms, and difficulty stopping despite negative consequences.
According to Statistics Canada, approximately 27% of Canadians aged 15+ used cannabis in the past year,
with 3-9% meeting criteria for Cannabis Use Disorder.

Cannabis contains over 100 cannabinoids, with THC (delta-9-tetrahydrocannabinol) being the primary
psychoactive compound. Modern cannabis products are significantly more potent than historical strains—average THC
concentrations have increased from 4% in the 1990s to 15-25% in flower and 70-90% in concentrates/extracts.
This increased potency correlates with higher addiction risk and more severe withdrawal symptoms.

Addiction is Real

Approximately 1 in 10 cannabis users develop addiction (Cannabis Use Disorder).
For those who start in adolescence, the rate increases to 1 in 6 (16%). Daily users have
25-50% chance of developing dependence.

Adolescent Brain Risk

Cannabis use during adolescence (when the brain is still developing) is linked to lower IQ,
impaired memory and executive function, increased risk of psychotic disorders, and structural
brain changes that may be permanent.

Withdrawal Exists

Regular cannabis users experience withdrawal symptoms when stopping: irritability,
anxiety, insomnia, decreased appetite, restlessness, and intense cravings. Withdrawal peaks at
2-6 days and can last 2-4 weeks.

Cannabis Use in Canada

According to Health Canada and Statistics Canada (post-legalization data):

27% of Canadians aged 15+ used cannabis in the past year (2023)
7% are daily or near-daily users (approximately 2.3 million Canadians)
Youth rates remain high: 20% of youth aged 16-19 used cannabis in past 3 months
3-9% of users meet diagnostic criteria for Cannabis Use Disorder
Impaired driving: Cannabis detected in 25% of fatally injured drivers in Canada
Mental health: Heavy cannabis use linked to higher rates of psychosis, depression, anxiety

How Cannabis Affects the Brain

Cannabis works by binding to cannabinoid receptors (CB1 and CB2) in the endocannabinoid system—
a complex cell-signaling system involved in regulating mood, memory, appetite, pain, and sleep. THC mimics
naturally occurring endocannabinoids (like anandamide), flooding the system and producing:

Euphoria: Activation of reward pathways (dopamine release)
Altered perception: Changes in sensory experience and time perception
Relaxation: Reduction in anxiety (at low doses; increases anxiety at high doses)
Impaired memory: Disruption of hippocampal function (short-term memory formation)
Coordination problems: Impairment of motor control and reaction time

With chronic use, the brain adapts by downregulating cannabinoid receptors and reducing natural
endocannabinoid production. This creates tolerance (needing more to achieve the same effect) and
dependence (requiring cannabis to feel normal). When heavy users stop, the endocannabinoid system is
dysregulated—causing withdrawal symptoms until the brain readjusts.

Health Risks of Cannabis Use

Short-Term Effects

• Cognitive impairment: Memory, attention, decision-making deficits while intoxicated
• Impaired driving: Doubled crash risk; THC impairs reaction time and judgment
• Acute psychosis: Paranoia, hallucinations (especially high-THC products)
• Cardiovascular stress: Increased heart rate; heart attack risk in vulnerable individuals
• Respiratory irritation: Coughing, bronchitis (smoking cannabis)

Long-Term Consequences

• Addiction: Cannabis Use Disorder in 10-30% of users (dose-dependent)
• Cognitive decline: IQ loss, executive dysfunction (especially adolescent-onset use)
• Mental illness: Increased risk of schizophrenia, depression, anxiety disorders
• Respiratory disease: Chronic bronchitis, lung damage (smoking)
• Amotivational syndrome: Reduced motivation, apathy, underachievement

Cannabis and Psychosis: The Evidence

Large-scale research has established a dose-dependent relationship between cannabis use and psychotic disorders:

• Daily cannabis use increases schizophrenia risk by 5x compared to non-users
• High-potency cannabis (>10% THC) carries even greater risk—especially in adolescents
• Those with genetic predisposition (family history of psychosis) are particularly vulnerable
• Cannabis-induced psychosis often precedes full schizophrenia diagnosis

Youth and young adults: The earlier someone starts using cannabis and the heavier the use,
the higher the risk of developing a psychotic disorder. If you have family history of schizophrenia or bipolar
disorder, cannabis use is strongly discouraged.

Signs of Cannabis Addiction

Cannabis addiction develops gradually. Common signs include:

Using more cannabis or for longer periods than intended
Unsuccessful attempts to cut down or stop using
Spending significant time obtaining, using, or recovering from cannabis
Strong cravings or urges to use cannabis
Failing to meet responsibilities at work, school, or home due to use
Continued use despite relationship or social problems
Giving up important activities because of cannabis use
Using cannabis in dangerous situations (e.g., before driving)
Continued use despite physical or mental health problems
Needing more cannabis to achieve the same effect (tolerance)
Experiencing withdrawal symptoms when not using

Cannabis Withdrawal Syndrome

Many people are unaware that cannabis causes withdrawal. Heavy, regular users (especially daily users)
commonly experience withdrawal symptoms when stopping:

Common Withdrawal Symptoms

• Irritability, anger, aggression
• Anxiety and nervousness
• Insomnia and sleep disturbances
• Decreased appetite
• Restlessness and agitation
• Depression and low mood
• Intense cravings for cannabis
• Physical symptoms: headaches, sweating, stomach pain

Timeline

• Days 1-3: Symptoms begin, irritability and insomnia prominent
• Days 2-6: Peak intensity—most uncomfortable period
• Week 2-4: Symptoms gradually improve but cravings persist
• Weeks 4-12: Sleep and mood normalize, cravings decrease
• Note: Some users experience protracted symptoms (low mood, sleep issues) for months

Treatment for Cannabis Use Disorder

There are no FDA-approved medications for cannabis use disorder. Treatment relies on
behavioral interventions, with several evidence-based approaches showing effectiveness:

Evidence-Based Treatment Approaches

Cognitive Behavioral Therapy (CBT)

The most widely studied treatment for cannabis use disorder. CBT helps identify triggers, develop
coping strategies, challenge thoughts that lead to use, and prevent relapse. Research shows CBT
doubles abstinence rates compared to no treatment.

Motivational Enhancement Therapy (MET)

Brief intervention (2-4 sessions) designed to build motivation for change. Particularly effective
for ambivalent users who aren’t sure they want to quit. MET helps resolve ambivalence and
commit to treatment goals.

Contingency Management (CM)

Provides tangible rewards (vouchers, prizes) for verified abstinence through drug testing.
Strongest evidence for promoting initial abstinence. Most effective when combined with CBT or MET.

Adolescent Community Reinforcement Approach (A-CRA)

Comprehensive treatment designed specifically for adolescents with cannabis use disorder. Involves
family therapy, social skills training, communication training, and development of non-drug activities.
Strong evidence for teen cannabis users.

Support Groups & Peer Support

Marijuana Anonymous (MA), SMART Recovery, and other mutual-help groups provide ongoing support,
accountability, and community. Free and widely available—important for long-term recovery.

What About Medication?

While no medications are approved for cannabis use disorder, research is exploring several options:

• NAC (N-Acetylcysteine): Amino acid supplement showing promise for reducing cravings in adolescents
• Gabapentin: May reduce withdrawal symptoms and improve sleep
• Zolpidem: For severe insomnia during withdrawal (short-term only)
• SSRIs: For co-occurring depression/anxiety (not cannabis-specific)

These are used off-label and should only be prescribed by a physician as part of comprehensive treatment.
The core of cannabis treatment remains behavioral therapy.

Special Considerations: Adolescents & Young Adults

Cannabis use during adolescence carries unique risks because the brain is still developing (continues until age ~25):

Higher addiction risk (16% vs 10% in adults)
More severe cognitive impairment (IQ loss, executive dysfunction)
Structural brain changes in regions governing memory, emotion, decision-making
Increased risk of psychotic disorders (schizophrenia, bipolar)
Academic underachievement and reduced life outcomes

For parents: Early intervention is critical. If your teen is using cannabis regularly,
professional help can prevent long-term consequences. Family-based treatments (A-CRA, multidimensional
family therapy) show the best outcomes for adolescents.
