Using cannabis can worsen your mental health*.
Three recent reviews of research studies indicate there is a lack of conclusive evidence that cannabinoids improve depression, anxiety, ADHD, post-traumatic stress disorder and psychosis.
Research shows little evidence that the cannabis plant is effective in treating depressive disorders and symptoms. In fact, the scientific literature suggests that ingested cannabis likely leads to the development and worsening of depressive symptoms.
Several studies indicate that cannabis use can worsen bipolar disorder by causing more manic episodes and increasing the severity of the episodes.
The research shows that when people use cannabis to escape from uncomfortable emotions, they can experience difficulties with mental health, including increased anxiety, psychotic symptoms as well as legal problems, low motivation, and memory issues.
Using cannabis to cope with emotions can also lead to addiction for some individuals.
* Applies to all forms of cannabis including medical marijuana.
