Why is everyone so judgemental?

So many nasty posts are left for my questions. People make so many umptions. I take NyQuil to sleep, I'm not an addict. I want to try codeine to see if I still have a reaction, not for recreational use. I want to use Adderall to help me focus in dental school so I can be the best student and subsequently dentist I can be. Why is everyone so judgemental? It's not like I'm some dope head. I'm responsible.
