Complicated: Marijuana is a very complex drug that has many active metabolites and complex interactions with your nervous system, so its hard to say definitively. There is strong evidence that it interferes with learning and that it makes mental illness worse if you have any predisposition. There are many studies witch suggests other problems but we are still studying this.
