Your vape will work fine but I'd only use it for dmt afterwards. It'll leave residue and the taste will stay so that's the only downside.

I did a 15mg dose my first time to get a feel for how strong it was going to be; had fractal patterns over everything and felt extremely disassociated. Then 15 minutes later I stepped it up to 30mg and had a pretty nice sub-breakthrough; I closed my eyes and was greeted by a bunch of circle headed entities. Some were running around chasing eachother and others were looking at super complex mazes. Eventually a whole group of them came up and surrounded me and started pushing me to a door in the distance and as I approached they opened it to reveal a multicolored spiral tunnel to which I jumped into. From the spirals in the tunnel a ladies face started to emerge form the spirals and just as it fully formed I floated down back into my body. Anyways I haven't written that down before and I felt like rambling bc I'm stoned......

Aaaanyways to avoid a bad trip you just have to meditate and focus your intent on having a positive experience. Dmt is a really strong hallucinogen, probably the strongest as far as its debilitating effects. If you show it respect and understand what you're getting into, you'll be absolutely fine. On the off chance you do have a bad trip, you have to remember that you brought yourself into that bad trip. When you come out of it you just have to remind yourself that all of it was just a bad trip, but if it was really bad try to analyze it and see if it could indicate anything going on in your life, and then integrate that experience going forward. I hope this helps and I wish you the best of luck.
