- Smoking or vaping cannabis can damage your lungs. Cannabis smoke contains tar and toxins similar to tobacco smoke.
- Avoid inhaling deeply or holding your breath to reduce the risk of lung damage.
- Second-hand cannabis smoke or vapour is harmful, especially around children or women who are pregnant or breastfeeding.
- The higher the THC potency in a product, the higher the risk of experiencing adverse health effects. High potency THC products can increase the risk of serious and long-term problems, such as injuries and dependence.
- The long-term health effects of vaping remain unknown. Vaping THC and/or nicotine has been associated with severe breathing problems that may require hospitalization. In some cases, deaths have occurred.
If you have a pre-existing health condition, speak to your health care provider before using cannabis.
Ingesting too much cannabis too fast increases the risk of experiencing negative side effects, these may include:
- Nausea and vomiting
- Anxiety or paranoia
- Psychosis, in extreme cases
Cannabis use can impact brain development for people under 25
Science has proven that your brain is still developing until about age 25. Why risk consuming unnecessary chemicals, like THC, when it could affect your development?
- The earlier in life you start using cannabis, the higher the risk for addiction and health-related harms.
- Research shows that attention, judgment, decision-making and your ability to learn can be affected by how early, how much and how often you use cannabis.
- Avoiding cannabis until your brain has developed just makes sense.
But hey, if you don’t believe us, see what the experts have to say at AHS, The National Academies of Sciences and Engineering and Medicine.
Long-term, frequent cannabis use can cause recurring episodes of severe nausea and vomiting known as Cannabinoid Hyperemesis Syndrome.
High potency THC
Cannabis extracts, also called concentrates, have higher THC levels, meaning they are more potent than traditional dried cannabis. Concentrates come in many forms and can include shatter, rosin and hash.
Research shows that regular use of products with a high THC potency can increase your chance of experiencing adverse effects.
These effects may include:
- over consumption or “greening out”, which can lead to vomiting and dizziness
- poor mental health outcomes, especially if there is a family history of mental illness
- increased chances of addiction — medically referenced as “Cannabis Use Disorder”
- psychosis, in extreme cases
