Cannabis Health & Safety

What are the mental health effects of cannabis use?

In some people, cannabis use increases the risk of developing mental illnesses, such as psychosis or schizophrenia. Any cannabis use is associated with a 40% increased risk of psychosis. Consuming cannabis can produce effects that induce mild or temporary symptoms of anxiety, paranoia and delusional beliefs or cause more permanent mental impairment.

Those who start using cannabis at a young age, use it daily, and have a family history of mental illness are at a greater risk. The effects and onset of these illnesses may also be worsened by using higher-strength cannabis products.

Frequent cannabis use has also been associated with an increased risk of suicide, depression and anxiety disorders. Cannabis use may also exacerbate symptoms of existing mental health problems, though further research is required.
