Cannabis (weed) is a psychotropic drug that affects the brain and can change your mood, how you think, your awareness or your behaviour.  

Weed comes from the cannabis plant that contains active chemical compounds including THC and CBD. To feel its effects, cannabis is smoked or taken orally (tinctures, oils, edibles, beverages). 

People use cannabis for many reasons. Its effects can vary greatly from one person to the next, and using it can have profound effects on your mental health.  

People who are predisposed to mental health conditions should be cautious about using cannabis, as it can worsen, or trigger negative mental health situations.  

Cannabis has been legal in Canada since October 2018. The only legal way to buy cannabis in Quebec is through the Société québécoise du cannabis (SQDC). Legal cannabis products must meet strict federal regulations.  

Illegal street cannabis is still sold and consumed, with higher risks. There is a reported increase in contaminated street weed mixed with dangerous substances (for example, fentanyl). People who use cannabis are encouraged to get it from trusted, legal sources.
