This has probably been done before, but nothing came up on the first page of search so I figure i'll do it anyway. This poll is only counting drugs you have tried, not regular use.
I realize there are many kinds of amphetamines, but for the sake of brevity I won't bother listing them all. Theres no intentionally listing in regards to danger or quality in my mind, although it might seem that way.
The only drugs i've ever used on a regular basis is weed, although I enjoy lib caps when they're in season, and peyotes when i have the money, thought never as often as i would like.
Its by no means a complete list, if you mention something i missed i'll add it to the poll.
