I recently had a very bad experience. I have been smoking on and off for two years and never had anything happen strange. Recently I was put on lamictal, which is used as a mood stabilizer for bipolar disorder and for people with epilepsy. I was on it for about a month. I had been off marijuana for about 6 months. I decided to start smoking again and did so. The bad thing is that on one occasion I went totally out of my mind talking and being paranoid. I kept smoking and started talking and acting psychotically. I was hospitalized and was in a mental institute for two weeks. I would like to know if anyone has had similar experiences while on this drug because I want to know if there was an interaction. Also I wouldn't reccommend smoking while on lamictal.
