Cannabis

Cannabis is a drug that can affect your mind and body. The physical and mental effects of cannabis vary depending on how much cannabis is used, how it is used, and what type of cannabis is used.

Choosing to use? Know the risks.

If you decide to use cannabis products, learn how to use it responsibly and reduce risks for yourself and others.

• Cannabis affects everyone differently. Make sure you understand the health effects of cannabis. 
• Cannabis products that you eat or drink (edibles) can be more intense than inhaling cannabis, but the effects of it take longer to occur. Be patient and go slow. Learn more about edibles.
• Choose edibles containing 2.5 mg or less of THC to avoid over-intoxication. Know your limits and learn more about THC.
• Over-intoxication of cannabis (greening out) can take the form of anxiety, panic, nausea, vomiting and symptoms of psychosis, such as paranoia.
• Alcohol increases the intoxicating and impairing effects of cannabis. It is safer to choose one or the other, not both.
• Edible cannabis products often look like non-cannabis treats such as chocolate, brownies and gummies. Ensure cannabis products are securely stored away from children, youth and pets to prevent unintended cannabis poisoning.
• Youth are especially vulnerable to developing dependence and problematic use of cannabis, as their brains are still developing.
• Cannabis use while pregnant or breastfeeding may harm your child’s development. Learn more about the possible health outcomes.
