What are the effects of consuming cannabis on mental health?

Consuming cannabis can produce effects that induce mild or temporary symptoms of anxiety, paranoia and delusional beliefs or cause more permanent mental impairment. In some people, cannabis consumption increases the risk of developing mental illnesses, such as psychosis or schizophrenia.

Those who start consuming cannabis at a young age, consume 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 consuming high-THC cannabis products. Frequent cannabis consumption has also been associated with an increased risk of suicide, depression and anxiety disorders.

Cannabis consumption may also exacerbate symptoms of existing mental health problems, though further research is required.
