Can heavy cocaine use for a few years by a 25 year old cause schizophrenia?

Question by nipsy3: Can heavy cocaine use for a few years by a 25 year old cause schizophrenia?
Or at least accelerate it in someone who may already have it?
My friend has always seems to have gotten depressed and upset easily, even before he did coke. He was always emotional. Now he’s becoming forgetful and seems to have two different personalities, or just total mood swings. His girlfriend said he sleep walks at night a lot and does strange things. Not sure if that has anything to do with it.
