I realize your dry sense of humor has kicked in here. And Lord knows, we know WHY you are cynical.

Society goes on. I am a social drinker, but it has never controlled me or interfered with my responsibilities, my social skills or my family life. Of the millions who drink socially here in North America, most of them use it as a minor form of social entertainment and release.
To me, there's nothing better than a cold beer on a hot day or a nice glass of wine to complement some fine food when I feel like it.

And I have smoked pot and I DID inhale. Over my lifetime, I'd say a good portion of the people I met smoked pot at one point or another. They're all normal functioning individuals.
Maybe only one two abused it. I certainly knew a LOT more people who abused alcohol, and even more who became alcoholics. I say tax it, control it and free up the court systems for the dangerous criminals and crackheads.
