although, having not done DMT, i am incapable of comparing the two, i urge you, please don't knock salvia. I had a few great trips on sally d; though it's a bit of a disquieting experience, it can be incredible. btw, try taking a gram of 40x in a single hit in a bubbler. I did it. it was AWESOME!!!!
Salvia is a full-fledged psychedelic. I just feel that DMT can take you places that Salvia can never dream of.
