To my knowledge there's no plant that can be vaped straight to get the effects of the dmt. The concentration of dmt is just too low and the trip doesn't last long at all so you need to get your dose all at once. It's my understanding that with phalaris arundinacea (and similar green dmt containing plants) the extract is super sticky, goopy and dark due to the chlorophyll and that it can be smoked but it's better to take it orally. That could be a good option for a mild trip and canary reed grass (phalaris arundinacea) grows wild a lot of places. Otherwise acacia confusa extract is supposed to be much more mild than that of mimosa hostilis.
