Just call me Captain Straightedge... as far as drugs are concerned anyway... I even avoid prescription painkillers when I'm injured.

I also wanted to add a little to what Irish said... alcohol is a drug, and a legal one, but out of the drugs listed above (except viagra, it's in a different class) it is the only one that can be taken without intending to or getting high. It can certainly be used to do so, but having a glass of wine with a nice dinner doesn't mean you're getting drunk.
