Salvia often has an extremely negative feeling associated with it. The initial smoking of DMT can be uncomfortable but with a proper dosage it typically causes a very positive feeling but not in the sense of any stimulant. It feels natural, loving and you can forget you have a body.

Salvia can have horrendous negative feelings. A smaller dosage of DMT can produce slight anxiety. Of course, these are anecdotal experiences but I'd warn against using salvia.

I would caution against Ayahuasca too as it's intense, last hours and can be very negative unlike smoking DMT.
