Yes Catbuds, P.M.s. But I can tell you that I have had the privilege to work with some really fascinating plants in the course of my "career". In all cases the primary focus was the presence of glandular trichomes, and what exactly, on a biochemical level, was going on in there. S. divinorum was used basically as a model organism for production of a specific class of terpenoids (at least one of which is the psychoactive element). Growing these plants in a consistent and healthy way was a challenge. Very susceptible to thrip and spider mite. Even a small infestation weakens and kills them. The plants are essentially sterile and are clonaly propagated. It is a plant with very deep connections with specific people. And it's hallucinogenic character is misused and misunderstood in our culture, IMO.
