I think anything that might put daiv or forum members in unwanted jeopardy should be considered very carefully. I also think that it's mostly clear that people here collect plants because of their looks and/or botanical properties, mostly when one is looking for plants because of 'substances' it really shows. so I would be cautious in who I send plants or seeds to, if I would.
another side to this is if the word 'peyote' was replaced by the word 'hemp' it wouldn't really have mattered if someone would want it to make rope of it, it would still be obviously illegal.
With apologies to the late Professor C. D. Darlington the following misquotation springs to
mind ‘cactus taxonomy is the pursuit of the impossible by the incompetent’ - Fearn & Pearcy, Rebutia (1981)
