For me, dependency and increased expectations. If I have to take drugs to succeed, then I'm stuck taking drugs throughout my career. The earlier in a career, the worse of a problem this is. Which is why I think doing this as a student to enhance academic performance is a particularly bad idea. You're in school to prove to yourself and others what you're capable of. Doing so with drugs that you're not willing to take for the rest of your life is only lying to yourself.
