If there’s a hole in your body, you can put drugs into it. (Do I have to leave a disclaimer? The blog is still new, so why not: I don’t use drugs and I don’t recommend them to you either, I’m just describing what people do.) Every drug seems to have a “right” way to take it. You drink alcohol, smoke tobacco, snort powdered cocaine, inject heroin, and booty bump ecstasy [1]. There will always be exceptions, but the route of administration seems to heavily impact the experience of drug use.
Excellent post. I've read that people also put coffee in their butt.
