Can I smoke cannabis if I am taking Effexor?

I advise you not to smoke it while takingffexor. Cannabis is known to cause psychotic/panic episodes. Because the psychoactive substance content varies from plant/variety to plant/variety, it is difficult to predict the degree of interaction and effects that cannabis may cause when used during chronic antidepressant treatment

However, if you are already a regular smoker and you need to start treatment withffexor. It is best to discuss this with your psychiatrist
