I am greeted by a chorus of midgets fanning me with palm fronds as I sit on a chair of gold and eat grapes in a relaxed position while scratching the mites from beneath my skin. Only while on krokodil of course.
Alcohol. I'm really careful with that, though. I'm not taking this drug very often. And when I do, I use it in very moderate amounts. Caffeine. From time to time. I don't really like drinking coffee, so my choices are a bit limited. Nicotine. Involuntarily. I'd like to make it illegal.
I'm not sure if there's more. Probably some pain killers when it was absolutely necessary.
