I just thought foil would work cuz when u smoke drugs on foil u are truly freebase ing
No offense, but for your information and to prevent misinformation, smoking on foil has nothing to with "freebasing". If you want to smoke some chemical, you pretty much have to have it in a "freebase" form for it to work. DMT is almost always sold as a freebase to begin with. Don't smoke salts, which most RC's (and coke) come as. Smoking a salt form is inefficient and bad for you.
Whatever you smoke out of, it should have a short vapor path. As soon as DMT hits cool glass it starts to condense again, thus part of your dose is sitting in the pipe and oxidizing.
My opinion: dab nail is too hot usually and the vapor path is too long. Yes, crack pipe and meth pipe are different, though I've never used either for it's intended purpose the "meth pipe" is the way to go once you establish proper flame technique. You can control the temp through lighter distance and rate of inhale, plus when it melts it just puddles and solidifies for later.
"meth pipe" is a poor way of referring to an "oil burner pipe", its the kind where the "bowl" is just a bubble with a hole on top. Allows for bottom heating and when the DMT melts, instead of running into your downstem or weed pipe, it can just sit in the bubble and be vaped again when you're ready.
