erowid really isn't the most reliable source of information.
"When smoked, DMT effects are shortlived and intense and the smoke is harsh and plastic tasting. "
this description is indicative of improper vaporization, properly vaped DMT is not harsh at all (you won't notice most of the vapors until your lungs are getting close to full) and it does not have a plastic taste. DMT SMOKE on the other hand is harsh and tastes like plastic. it also requires a higher dose that DMT vapor would (as you are losing so much of the molecule before it even gets to your lips)


if it takes you more than 35mg to breakthrough, there is probably something wrong with your technique.

i weigh about 105kg/230lb and 25mg is more than enough to breakthrough if properly vaped and taken in one inhalation.

50mg and i would probably black out (or be close to it) 60mg is almost 3 doses for me (and 3 full doses for many others)...


generally, if you disregard erowid entirely, no real info of value is lost.


also, as far as the size of the bong goes, it doesn't have to be super specific. basically you want to vape all of the dose in a short time, and ingest all the vapor in one inhalation (then hold the inhalation in for as long as you can/is necessary) so if it is too large of a chamber, you won't be able to clear it as there is no room in your lungs.

i would say you want the bong only tall enough so that water splash in your mouth is a non-issue. the width really doesn't matter, so i say to go with whatever feels most comfortable on your face.
