Nope. FWIW, I think they should be in the same category for purposes of the survey, I’m just not sure what to call said category. I’d also put methcathinone in said category (though I hope nobody around here is using it for productivity purposes). Cocaine might deserve its own category.
Nitpick: Ritalin is not an amphetamine (no alpha methyl group), though it is a phenethylamine.
Ah, my bad. I thought Ritalin was another mix of salts like Adderall.
