Oh man! Why oh why did you go that route, unless you're looking for light dmt buzz. I don't think the lightbulb method would work with enhanced leaf, or anything for that matter...Why didn't you just throw it in a bong/bowl/weed pipe? Even a cheap little weed pipe would be more efficient than a cigarette, re-packed. I just can't see that going well, but I guess you had luck,ha!
Having no gvg, and a very poor freebase smoking technique, I pretty much always use enhanced leaf-mullien- with ACRB extracts . I love the roa because once you know the strength of the extract, it's very easy to dose. Personally I find it much easier to smoke a bowl of EH,than to try a freebase method like a lightbulb or oil burner or such. Just let it cherry, and smoalk away! It's never harsh or tastes burned. It's definitely not the most efficient route, but pretty sure fire, and a good way to begin to explore hyperspace.
Mixing it with tobacco, weed, or diluting it with plain herbs to flesh out a joint is a nice thing to take out on a nature walk, far, far from people. EH is very versatile, one can dose small or.dose big easily.
I'm curious, by 100mg, you meant 100mg of dmt, or 100mg of leaf? I'm sure that's a really dumb question, but I'm thinking you mean leaf since it's only enough to partially fill a cigarette tube, so how much DMT are we talking about ?
