I read somewhere, although I can't remember where, that in a foreign country (Russia i believe??) doctors at one time gave out AMT Hcl in 5 or 10 mg tablets as an antidepressant. If anything that much will probably give you a nice mood lift and a little spacey.
If you smoke it, do you know if you have the freebase or the salt (Hcl)? It'll pry make a difference...
Tried AMT freebase once at 12 mgs smoked, it totally turned me off from trying it again. I can concur concerning the negative effects, headache, nausea, uncomfortable stimluation. To this day it is one of the only substances I've tried that I didn't like in any way. I have given doses to friends orally with very positive results, but that one base experiment has kept me from doing any more. My curiousity is building though... See what the future has in store.
