I totally agree. But here's a question that I never really thought about until now. Shouldn't other activities such as smoking a cigarette or anything else of a legal but destructive manor to oneself. Doesn't that also classify as being unSatanic? (I don't know if this is an issue that has been brought up before). But, thats just the way I see it.

Every choice has its cost. Many indulgences can have health effects. The Satanist takes responsibility for his choices.

Alcoholism and addiction to hard drugs are not indulgences, they're compulsions. They are inherently irresponsible. In this respect, they can't be compared to caffeine, nicotine, or temperate social drinking.

Only if you do it in a Bar in Manhattan...

It has been brought up...repeatedly.
Magister Nemo summed up the issue, visually.

This is not a matter of morality. This is not Sunday School.
It is pragmatic.
Magus LaVey explained clearly why mind altering drugs are not Satanic. Read "The Satanic Witch".

Pragmatically, breaking the law will land you in jail. That puts a damper on seeing your will done, mastering your domain or being able to walk through your day unmolested.
