Recreational Drugs

What drugs would you classify as being recreational?

I know, I know, all drugs can be used recreationally if you know the difference between drug use and drug abuse, but I personally think that hard drugs like cocaine, meth, heroin and crack cocaine are not to be used for recreational purposes, you get addicted to it before you even notice and quitting them is huge pain in the ass cause of the physical withdrawals and what not.

What are your thoughts?
