Know the Link- Understanding Psychosis
Know the link
Cannabis might seem like a common way to relax or fit in, but it's important to know how it can affect your brain, especially when you're young.
One serious risk linked to cannabis use is something called psychosis.
What is psychosis?
Psychosis is when someone loses touch with reality. This can include:
- Hallucinations: Seeing or hearing things that aren't there
- Delusions: Believing things that aren't true or real
- Confused or disorganized thinking
It can feel scary and overwhelming, and it's not just a "bad trip".
Psychosis is a real mental health condition that can last for weeks, months or longer if left untreated.
Cannabis risks and ways to lower them
-
How cannabis increases risk
Using cannabis (commonly known as weed) can raise your chances of developing psychosis. Here's why:
- Your brain is still developing until around age 25. Cannabis can interfere with that process.
- Stronger weed, more risk: Today's cannabis often has higher levels of THC, the chemical that makes you feel high, Fiand it also increases the risk of psychosis
- The more you use, the more the risk grows, especially if you use daily or start young
- Some people are more vulnerable, especially if you have a family history of mental illness or you’ve had anxiety, depression or trauma
-
Lower your risk
- To reduce your risk of developing psychosis, avoiding cannabis use is safest. If you're not ready or able to stop using, practice harm reduction, follow lower-risk guidance and cut back on how much you use.
- People use cannabis for many reasons, such as socializing, exploring, cope with stress or mental health challenges. However, cannabis use can harm your health. Consider safer ways to manage stress, anxiety or trauma.
- Understand the product you're using. Learn how to read a cannabis product label and understand the THC level and potency of the product you're using.
