Reddit mentions of Zico (Original) Ergo Refillable Butane Adjustable Torch Flame Lighter Goldish Silver

A couple things:

If you use a torch lighter you don't have to worry too much about the flame touching the ceramic filter. The issue comes with using standard lighters which create soot. If soot builds up on the filter it can become clogged. Torch lighters burn much cleaner and therefore aren't really an issue.

Regarding the screens. Sometimes, even when using a large number of screens, the DMT can drip through them and end up being wasted. A common practice is to use some Chore Boy [Walgreens carries it] and use that as a bed [place it on top of your screen(s)]. Be sure to soak it in isopropyl alcohol prior to use [to clean any impurities]. Dry thoroughly, cut off a small portion, roll it into a ball, and then flatten. This wad of copper wool "catches" the DMT as it's heated so that it has nowhere to go, ensuring you receive the full dose. The second, and probably "cleaner"/less of a hassle option is to purchase a ceramic flavor disk. Both serve the same function: to prevent the DMT from dripping to the bottom of the pipe.

Regarding a sitter, since this is your first time it wouldn't hurt. But you'll soon find that it's not necessary. More important, I think, is set and setting. Be in a good headspace and find a place free from distraction where you can sit back and relax after blast off.

Lastly, I'd suggest investing in a scale that measures 0.001 gram increments. The Gemini-20 is inexpensive and reliable. Start with a dose between 15-25mgs. You can clear the pipe in one long slow toke.

Best of luck - enjoy the trip and let us know how it goes!
