Thier is proven facts from doctors and psychological professors that weed in the long term does not affect physical or mental state. One doctor when asked if he thought smoking weed would give you difficulties in later life, he replied "there's as much chance of you having one glass of wine and becoming an alchoholic as thier is of thier being any mental or physical difficulties from smoking a joint".
