I learned at a panel at Eugene Cannabis Science Pub that terpenes are where the action is. Rather than higher THC percentages, important new research directions are identifying various terpene cluster synergies. Of 20-30 terpenes in cannabis, 8-10 have the most action. Researching cannabis adult use and medicine: forward ho to the next frontier, inner space healing. 

One terpene cluster may help PTSD: others sleeplessness, cramps, cancer, sexual function. Terpenes exist in most plants: pineapple, pine scents.

Another intriguing development: accurately calibrated vaping devices can set degrees F. to maximize desired effects of various terpenes since some activate at different optimal degrees. 

Who would have thought that marijuana could evolve such a creative potpourri for mind expansion, insight, medical purposes and improved sexuality? Older folks dig it to prevent depression.

ps Some vaping devices cost $500 but a simple vaping device, even solar, can be cheap.
