It can. Generally, if you're going to develop a mental illness, it will come on in your early adult years...18-24 or so. Family history, enviornment, and drug use all play a part into it. Like already said, it's a real good idea to checked out and know your history before you do any type of drug, including alcohol. If you have preexisting factors, drug use can expose and bring out mental illness.

myselfandi couldn't have said it better...know thy self!
