If you sourced your plant from STS, it has been tested via TLC with GC/MS confirmation to contain DMT. Several reports of smoking the leaves also indicates activiy but no one to my knowledge has yet made a brew with the plant. The STS plant has not been positivelly ID'd as D. cab, in the western botanical sense but is used as a chaliponga in Ecuador according to the vendor.
If your source was other than STS I can't tell you what you got, but I'd like a cutting!
I already asked Alice.
