I had a thought.
For those e-cigarettes they dissolve the nicotine and flavors in propylene-glycol, polyethylene-glycol, or glycerine. As I understand, the real issue here is to get it into a concentrated enough liquid, but also be breathable. I don't know if DMT is soluble in glycerine or not, but I have a bit of recovered stuff from evaporation dishes that's been laying around, so I may give it a try. Also, I don't know if the glycol would nebulize, either.
I'm not sure if the nebulizer works at a specific frequency to atomize water, or if any high frequency will do with sufficient amplitude. I was thinking that one of those ultra-sonic humidifiers/foggers may be able to be modified to produce a different frequency that may work for an oil/glycerine.
Also, what about using one of those e-cigs for DMT? Could work, too.
