At least those who drink alcohol don't usually claim that it's for "medicinal purposes." Unless they wink their eye when doing so.
I just wanted to add something else to my post above. With alcohol consumption, at least we, and the greater society at large, are aware of the dangers of excessive alcohol consumption.
But with pot it's different. For some here on the forum, it's like a miracle substance, with little or no side effects. Well, that's a dangerous assumption - to assume that there's nothing wrong with pot smoking. I'm surprised, really, that trads would be taken in by this assumption. But then we do have a resident manipulator and bully on this forum who enforces this assumption, and who strives to ensure that NO ONE goes against his directives. Most unfortunate.
