Hi Ash,
I have a friendly suggestion for you, to do some more research on subject before you take your jar out of fridge. DMT is very interesting read and experience :d
for instance...
1.DMT is indole based hallucinogen among LDS, psilocin, serotonin etc. I think it's second simplest indole (tryptamine) molecule in ecosystem after serotonine. Good news : it is safe, human body knows it, there are mechanisms (MAO) ensuring of short safe trip
N,N-Dimethyltryptamine - Wikipedia
2.DMT delivers level 4 or 5 psychedelic experience

3. If you do it right (and you're lucky) it CAN put you on 'shamanic path'. I was given 'lucid dreaming' ability which I have to train to keep. This is very interesting subject (sleep paralysis, astral projections...)

4. to answer you questions...take out jar from fridge, pour naphtha out (keep it) and dry DMT. Smoke it in bong between two layers of herb or ashes. Don't smoke caapi shredded root bark with it (guess). Expect to have intense trip, half hour afterglow (LSD like), vivid dreams later on and for me, my mind is calmer for next 2 days, sometimes not.
All this is just suggestions...I had a great time reading 'DMT - the spirit molecule' by Rick Strassman. Wikipedia is just for reference...
I wish you luck with your research :d
