What are the risks of using cannabis?

Cannabis use comes with several potential risks. It has been associated with an increased risk of mental health disorders, particularly psychosis. Studies indicate that heavy cannabis use, defined as more than twice per week, can heighten the risk of psychosis fourfold, especially in individuals with a family history of disorders like schizophrenia and bipolar disorder 1.
Additionally, cannabis consumption is linked to cardiovascular issues. While the data isn't entirely conclusive, there is a potential increase in the frequency of strokes or cardiac events among users, especially those who smoke 2. Cannabis use can also lead to a syndrome known as cyclic vomiting, predominantly affecting heavy users, which bizarrely can be alleviated by hot showers 3.
Moreover, the development of cannabis use disorder is another concern. Estimates suggest that about 30% of weekly users may meet the criteria for this disorder, indicated by behaviors like prioritizing cannabis use over other responsibilities or risking legal trouble for access 4.
For young individuals, using cannabis during adolescence significantly raises the risk of long-term psychiatric issues, including severe anxiety, depression, and psychosis, as it affects the developing brain 5.
