Cannabis seems to be one of the drugs of choice of individuals with bipolar disorder, despite evidence that manic states can be induced by its use Cannabis abuse also occurs frequently in individuals with anxiety disorders, but the relationship between the chronic nature of these conditions and the use of marijuana remains uncertain In respect to depression, there is no clear evidence to date that depressive patients use can nab's as a form of self-medication In individuals wall psychiatric disorders, the use of cannabis has been associated with Increased positive symptoms, additional negative symptoms in the course of illness, impaired treatment compliance, and more hospitalizations Conclusion: The abuse of cannabis by patients with psychiatric disorders such as schizophrenia and mood and anxious disorders has a negative impact both in the acute and advanced stages of these conditions, although further investigation on this association is still necessary
