Well, I'm a bit ashamed in answering, as I'm a quite spiritual user of the spirit molecule and am not sure You're fully in the nexus attitude.
Anyway, in my opinion anyone deserves to have access to DMT.
Just try to find the better naphtha You can. Zippo lighter fluid works very bad, it's full of impurities and it's harder to separate. Also, the better is the naphtha, the less You should strain the mix: I just turn it upside down for, say, 15 minutes, than leave it under warm water for while: that makes separation faster (about 15 minutes). If I shake the mix, it takes up to 1 day or 2 to be perfectly separated. Having a closed container is mandatory, but it should be opened some times to avoid pressure buildup.
I usually evaporate the naphtha avoiding freezer precipitation. This is not the best method but it's simple. I would suggest it for first times. Using a fan will make the whole naphtha to evaporate in 3-8 hours or overnight. Use room temperature air, not an hair dryer. I usually tilt the glass pan when the naphtha had left a mainly solid residual (it uses a couple of hours), which allows the fat yellow fluid to flow down separating from crystals (this process may take several hours). Sometimes, to have dryer crystals, I wait a couple of day.
You could eventually find a yellow goo instead of white crystals, that should work anyway but it's not so pure and it's more difficult to move/use. For the final test, smell the compound: if it's floreal, that should be good, if it's more like mothballs, you still have some naphtha inside and may want to redissolve it in acetone, which is less toxic.
Please note all these info could be found around the nexus, so my suggestion is to take the more time You can reading and studying.
Hope that helped.
Peace and good luck.
