Meth smoking - Harm reduction?

[amphmnamii]

Smoking meth is very entertaining for me and much people around the world. However meth needs heat to evaporate (~170°C depends on meth structure and purity) and people usually overburn it. Then meth molecules Starts to decay, and usually turns black.

My question is, what is this residue of meth, and how to ruduce inhaling poisonous substances from glass pipe.

I have tried burning at lower temperature, and I tried to spread surface of melted meth, but it's not effective at all.

Any ideas?

It depends on how it was made, WHT route and also temperatures and excesses. This document breaks it down really well. The bestbway to avoid them I'd to buy quality product. Meth shouldn't turn black for a long time. Never really unless you burn it to a crisp. Sounds like you aren't getting methnor you are gerring heavily adulterat3d meth. Got a pic?
