For me it’s driving while under the influence. If you couldn’t tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can’t fathom. I’ve only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
It definitely sucks, but there are an increasing number of people like Ian of Forgotten Weapons getting people interested for the same reasons I am, really only getting into the politics from the historical or design perspectives, and always in a very objective manner. I’m also now in a far more liberal area and the local ranges are very inclusive, so that helps immensely.
