a friend was wondering what the dosage would be for snorting the DMT Fumarate? How do the effects differ from smoked dmt freebase? how long does it last?

has anyone ever experimented with this?

it would be very cool to have some kind of little bioessay on different doses and their effects.

does the fumarate also work sublingually? or will it be broken down by MAOi there as well?
