I have been taking Adderall XR 30mg for quite some time and have never had any problems on it. I was at a party recently and was moderately drinking (I only occasionally do so knowing possible interactions) when it is believed that I could have been unknowingly given an additional substance (marijuana was one theory, am planning on getting labs done to check everything). I apparently starting acting pretty crazy, yelling at people, crying, talking out of my head and possbibly hallucinating. I have no recollection of any of this but was informed by my friends of everything afterwards. This lasted for at least two-three hours until I went to sleep, waking up 10 hours later. Luckily most of my friends work in the medical field and kept close watch on me. Is it possible that something given to me could cause Adderall psychosis?
