get a reg metal pot pipe with a screen, light a ciggerrette, and ash into the bowl, packing it down a bit n shit, so when the smokes down the screen should be covered with ash n the rock shouldnt run threw.
Just do heroin, a lot easier on your body lol. If you're hell-bent on destroying yourself, get a glass tube, like the kind they sell certain cigars in or the kind for lab projects and make one out of those. Seen people make DMT pipes out of them, same idea.
i've used the glass part of an eye dropper for 5meoDMT before... i imagen it'd work the same. it's kinda difficult though, since there isnt anything to catch the stuff and it gets pretty hot. or else, like other people are saying, any sort of glass tube. smoke shops and head shops usually have glass insence or cigar containers that look suspiciously good for that stuff. http://www.erowid.org/chemicals/cocaine/ http://www.erowid.org/experiences/subs/exp_Cocaine.shtml
crack would need a direct flame, it is not vaporized like dmt, 5 meo dmt etc. Take weedmans advice. Even better though, go eat some mushrooms.
Ahhh you can burn it with a direct flame, but basepipes are heated from the outside, causing the rock to melt bubble and give off vapors.
