The only problem with the survey is that I've had dissociatives and amphetamines as a kid because of all the nitrous they gave me at the dentist office and the ritalin and adderal I was prescribed. They just ask which drugs you have tried. They don't ask if you took them legally or illegally. I never took speed for fun and don't like its effects, but I had to answer that i took it "recreationally" because that's the closest answer in the survey.
