When Cannabis Use Becomes a Problem: Signs to Watch For

In this article

Cannabis use exists on a spectrum. Some people use cannabis without developing a substance use disorder, while others find that use becomes increasingly difficult to control or begins to interfere with health, relationships, work, school, finances, or safety.

The important distinction is not whether someone fits a label such as “casual user” or “addict.” It is whether cannabis use is creating harm, becoming more frequent or intense than intended, or continuing despite repeated problems.

Signs Cannabis Use May Be Becoming Problematic

Patterns that can be concerning include:

• using more cannabis, or using for longer, than intended;
• repeatedly trying to cut back without being able to do so;
• spending substantial time obtaining, using, or recovering from cannabis;
• experiencing strong cravings or urges to use;
• missing or neglecting responsibilities at work, school, or home;
• reducing important social, recreational, or work activities because of cannabis use;
• continuing to use despite recurring relationship, physical, or psychological problems;
• using cannabis in situations where impairment creates a safety risk;
• needing more cannabis to achieve the same effect;
• experiencing withdrawal symptoms when reducing or stopping use.

A clinician considers the overall pattern rather than one behaviour in isolation when assessing cannabis use disorder.

Frequency and Risk Matter

Frequent or high-intensity cannabis use is associated with greater risk of cannabis-related problems. Health Canada’s lower-risk guidance recommends avoiding frequent or intensive use and notes that risks can be greater when cannabis use begins at a younger age.

That does not mean every person who uses cannabis daily has the same diagnosis or level of impairment. It does mean daily or near-daily use is worth looking at carefully, especially when the person relies on cannabis to sleep, cope with distress, function socially, or get through ordinary responsibilities.

Cannabis and Younger People

The developing brain continues to mature into the mid-20s, and earlier, frequent cannabis use is associated with greater risk of adverse outcomes. Risk is influenced by age of first use, frequency, product potency, individual vulnerability, and other factors.

For adolescents and young adults, delaying use and avoiding frequent or high-potency cannabis can reduce risk.

Cannabis and Mental Health

Cannabis can interact with mental health in complicated ways. Some people use it to cope with anxiety, low mood, trauma symptoms, sleep problems, or stress. In the short term, that may feel relieving. In other people, cannabis can worsen anxiety, impair motivation or concentration, or contribute to other problems.

Frequent cannabis use is also associated with increased risk of psychosis, particularly in people with other vulnerabilities. If cannabis use is accompanied by paranoia, hallucinations, severe confusion, or a marked change in functioning, seek medical or psychiatric assessment.

Safer Choices If You Use Cannabis

The only way to avoid cannabis-related risk completely is not to use it. For people who do choose to use cannabis, Canadian lower-risk guidance includes reducing frequency, avoiding impaired driving, delaying use until later in life, and being cautious with higher-THC products.

Never drive while impaired by cannabis. If you are using cannabis to manage a medical or mental health concern, discuss that with an appropriate health professional rather than assuming it is harmless because it is legal.

When to Seek Help

Consider seeking support if cannabis use feels difficult to control or is interfering with health, safety, relationships, work, school, finances, or important activities.

Treatment does not require someone to accept a stigmatizing label. Therapy can help clarify what role cannabis is playing, identify triggers and coping patterns, address co-occurring mental health concerns, and build a realistic plan for reducing harm or changing use.

Bayridge Counselling Centres provides psychotherapy and counselling across Ontario through regulated mental health professionals. Medical concerns related to cannabis should also be discussed with an appropriate medical provider.
