Well, my first question would be, are you synthesizing your own DMT? Because i mean, if you are, then i would say you should go ahead and try it to see if it would work for you since you will probably want a meth pipe for that meth anyways and you'll most likely have a ton of spice. The real problems with it won't lie in the pipe itself, it'll be in how you use it. I can't say there aren't worse ways to smoke DMT because that wouldn't be true. It just won't be as easy as something like "the machine". Not sure how that crack pipe worked for you but that's probably one example. Lol. But if you do try with the meth pipe, it will be a pretty harsh smoke, which will probably cause you to cough, which is where the wasting will happen since you want to hold in each hit for a few seconds. Also, make sure you take soft, smooth drags because the DMT will be much closer to your mouth and i know i wouldn't want any spice in my mouth. And also, make sure you're really careful with the lighter distance because it'll be really easy to burn and that's where a lot will be wasted too. Other than that though it'll probably be fine. I've heard of some people liking this method, it just wouldn't be my first choice. That's for sure.
