Like every aspect of our behavior and who we are, it's most often a combination of factors. Plenty of people rely on drugs for self medication, plenty of people end up using for fun or to try for other reasons (fight pain etc) and end up with a dependency. It's in our nature to point to a single cause of everything but that's rarely the case.
