Cannabis is a plant known by many names, including marijuana, weed, or pot. Some common forms of cannabis include the dried flower, edibles, oils, extracts, tinctures, creams and capsules. People consume these products for both medical and non-medical purposes.
The cannabis plant contains over 100 different chemical compounds known as cannabinoids. When consumed, these compounds affect the brain and other parts of the body. The two most common cannabinoids are:
- THC (aka delta-9-tetrahydrocannabinol) is the psychoactive compound found in the cannabis plant and is responsible for the way your brain and body respond to cannabis, including the intoxicating effects or feelings of “high”.
- CBD (aka cannabidiol) is the non-psychoactive compound found in the cannabis plant and is not typically associated with intoxication or feelings of “high”.
Residents 19 years and older are permitted to purchase, posses, and recreationally use non-medical cannabis within Newfoundland and Labrador. Understanding the laws and regulations around non-medical cannabis use in Canada and this province is an important part of staying safe.

Delay as long as possible. The earlier in life you begin cannabis use, the more likely you are to experience serious health effects.
Always purchase cannabis products from a licensed retailer, whether from a local store or online at ShopCannabisNL. Synthetic cannabis products (i.e., K2, Spice) are dangerous and can cause serious health problems.
Choose safer methods. There are different ways of using cannabis and some are safer than others. Smoking cannabis causes the most harm. If you do smoke cannabis, avoid inhaling deeply or holding your breath.
Start low and go slow. Choose products with a low amount of THC and an equal or higher amount of CBD.
Stick to one. Mixing cannabis with tobacco, alcohol, or other substances will increase impairment and the risk of serious health effects.
Impaired driving is 100% preventable. Cannabis can impair your judgment, reaction time, and increase your chances of being in an accident. When using cannabis, it is important to wait at least 6 hours before driving or operating a motorized vehicle. It is also best to avoid combining cannabis with alcohol and other substances as this increases your level of impairment.
Some people should avoid use. It is safest to avoid using cannabis if you are pregnant or breastfeeding, or if you are at risk for mental health or substance use problems.
Practice safe and responsible storage. Keep cannabis products in a safe place out of reach from children, youth, and pets. Cannabis in food products (edibles) can be especially tempting to curious children. If a child accidently eats or drinks cannabis, seek medical attention right away.
