You know I made a thread about this a while ago

here

Water is not going to steal any noticeable portion of DMT and condensation takes A LONG time.

There has been some conjecture to that effect, but it's been a fairly popular method for some time. SWIM'd wager that one could smoke through the night, and so long as the methods sound and the product's mostly pure, evaporating the bong water wouldn't turn up anything of significance, nor would evaping an IPA wash of the bong. In any case the power of the delivery and consistency of effects compared to dosage would be worth whatever small minuscule loss imaginable.

Hello Guys.. I'm new here and this is my first post

I'm planning to use a bong with some water. I was thinking of using the sandwich, so putting some herb or tobacco on the metal grid in the "straw" of the bong then the spice and then some other herb.

But then: how do I avoid burning the spice??
I've read that burning the outer layer of the sandwich and then putting the flame off should be enough...

Please help.

Peace and love

Can you use a bowl like this and heat it from the bottom?

Yeah. Ideally you want a rig with less glass between you & the vapor though. The vapor will crystallize on the glass in the percolators & throw your dose off more & more each use.

Dont heat the glass banger (bowl) with flame with the DMT in it. Heat it red hot with a torch, wait 10 seconds, then drop your dose in & hit the rig.
