Greetings, SWIM will also be testing elemi oil as well as some combinations in the future.  Do you know if it's the caffeine in coffee that potentiates mescaline and (likely) elemicin?  SWIM is very sensitive to caffeine, even the 10% caffeination in Decaf Coffee gives her a strong stimulant effect, so hopefully I'll be able to use Decaf in these experiments.  Also have you tried Yerba Mate as a potentiator for LSx/Mescaline?
