Political taxonomy of drugs

Left-leaning political blogger Josh Marshall commented yesterday on the idea that drug choices play out differently at different parts of the political spectrum, commenting on recent inside memos from the Teabaggers, as well as reports that the nutjobs of the Christian Hutaree militia were into crack cocaine:

But any kind of cocaine, crack or otherwise, just wasn't what I was figuring. (Just as a side note, perhaps we can all agree that the 2nd amendment shouldn't apply to coke addicts. Who's with me on this?) Not that coke ain't a thing on the right, just not that right. That's more your Wall Street/libertarian supply side type...

Today, another comment was added from a reader who seems to have partied all around the political landscape:

First of all, in my experience, Marijuana is used by all political stripes. The leftist hippie protester could easily buy some really high quality outdoor grown "kind buds" from a militia member. I had a formative experience getting high in Bozeman MT with some scary right wing militia types. I have met a lot of conservative people that would have no problem dropping acid or taking shrooms if they wanted "party". A big supporter of Obama here in Mt Pleasant was also married to a coke dealer, and I have a few hippie friends that have back problems that seem to require a lot of oxy's. Pills are rampant across many demographics, adderall, oxycotin, etc.
In my opinion, if you want to get high, you only are supporter of the party you are having at that time.

And that seems like some real wisdom there.
