I just hate when people refer to an "Oil Pipe" as a "meth pipe" or "dope pie" one of my good friends used to do meth and I had a huge problem with him referring to my oil pipe as a "dope pipe" (I told him "I don't smoke dope anymore and you don't either, if I catch you doin dope again, I'll kick the shit out of you. This is an oil pipe and will be referred to as such"). Oil pipes are not dope pipes and they were not designed to be used for "smoking dope". Also on that note a straight tube incense burner (what people refer to as "crack pipes") works better unless you modify the oil pipe, still, a lil Brillo or steel/copper mesh (burned clean) in either and you're good to go. (convection > conduction)

Now, in response to the "Waxy DMT is the worst" comment, I just have to say, that the Deems I get is more of a waxy goo (JimJam) and is completely food grade, no nasty chemicals or solvents and I personally prefer it that way...
