Welcome to the Nexus!
I think with DMT as your first psychedelic you have to extract
it yourself. When you finally reach your goal you've learned lots
of new skills and gained a solid relationship with the sacrament.
Start low and slow! Get a proper vaporing device like a GVG or a Bong.
Start with 10mg to test the behavior of the substance, how to
melt, how it smells and how to inhale. Then increase in 5mg steps.
I smoke FB DMT in a GVG and the Changa in a small (Glass-)Pipe.
I find it amazing that still so many very young folks are interested
in psychedelics, especially dmt.
I experimented with LSD and Shrooms, starting about your Age, but had to
wait 20years to extract DMT.
I knew about this exotic tryptamin (from a real Book) but there was no dmt
around and the knowledge of extraction was many years in the future, as well
as the Internet.
