Iowasca is the hallucinagen that causes the same trip in everyone who takes it.
DMT is one of the components of the powder that the yanomano tribespeople blow up each other's noses to have mystical experiences.
DMT used to be referred to in my day as "the businessman's lunch" because you could take it and come down completely in 15 to 30 minutes and experience a very unique clarity.
It is powerful and should not be taken without spiritual guidence imo.
I met T. McKenna back in the day and still own a few of his lectures on tape. There is a bunch of his stuff available in the Pacifica Archives.
20 plus years of being a Dead fan did provide some education into these subjects...
