ive been on many psychiatric meds...sereqouel,lexapro, clonzepam, abilify, welbutrin, celexa, lamictal, loranzepam, geodon, and im probably forgetting some and the only one that i could tell interacted different when i smoked pot.. it would intensfy to a point of sickness, dizzyness, first time i smoked on that medicine i puked everywhere and couldnt walk more than five steps without laying down on the grass, i was laying in random peoples yards and they were asking me if i was okay; it took me an hour to seriously walk a block from the waterfall on the golf course to the street corner so my stepdad could pick me up; then i passed out in the back of the car for a long time... it was probably one of the worst drug induced sickness ive ever had.
