Point to ponder: a few folks have pointed out that if we are looking to "mind altering" substances to enjoy ourselves, then we need to examine where that need comes from. If one can't have fun on a clear head, then that's not a good thing.

Then we have folks that are pointing out (quite correctly, IMO) that BDSM is mind altering all by itself. I know, for me at least, this is true: I have gotten a better high off subspace than any amount of drug or alcohol I've ever taken.

Soooo... We all do in some way, it seems, need our minds altered and our otherwise clear heads fogged up a bit. Who's to say that this doesn't make our play as equally irresponsible as if we were taking a few shots beforehand?
