so basically tell me if this would work
put some isopropyl in a shotglass
mix in desired amount of dmt
mix in any herb (i'd probably use something found around house mint leaves or parsley)
let sit for several days to evaporate
do i now have smokable DMT?

and also how do i go about smoking this? cherry it i assume then slow-medium or fast rips?

the dmt must be in freebase form and dissolve into the Isopropyl Alcohol. So long as it will dissolve, it'll work. Just wait until the alcohol smell is gone then smoke the dmt-herb.

Without harmalas one would need to ingest it as two long-held hits back to back.

regarding method of smoking, check the FAQ

good luck!
