uh
there's an issue with the glass tube thing.
all glass tubes are not test tubes =P if you heat a cigar tube, it could explode when you heat it, and even more likely it could explode when it cools. when glass explodes it's not all that good, especially if you're trying to smoke drugs out of it.
and tweakers, you KNOW you'll try to smoke the (real) shards of (real) glass trying to get drugs off them... and probably try to snort some of it too.. so.. this is what you do:
do not use glass cigar tubes because they break.
really, scientific glassware isnt the way to go with this kind of thing.
it's not designed for crack-purposes.
actually, it seems like you almost always get the vapor refluxing/resubliming on the glass... you need to constantly be sucking on it to get anything, and even then you usually get a ring of crystals that's damned hard to get at... youll probably end up having to heat the whole thing slowly and get the ring to move upwards until you eventually smoke all of it, hoping of course that you don't make it decompose first. usually you will end up with a lot of useless charred carbon and no drugs.
the best results are obtained by doing something crackheaded, usually involving aluminum. examples: a can, a pen. weed smoking devices work too if you adapt them.
oh
yeah
one other thing i found out
tweaking destroys you
im kind of obligated to say that
because i want it, and i know i shouldnt do it.
