The argument "it's wrong to group synthetic cannabinoids with weed because they're untested" could equally apply to PD- "it's wrong to group RCs with mushrooms and cacti because they're untested". PD isn't a place for all RC discussion, it's a place for psychedelic RC discussion. By the same logic, cannabinoid RC discussion belongs here.
As for the terpene/indole argument...shouldn't there be a seperate dissociatives forum then? I mean, they have not only different structures to psychs, but affect different receptors entirely.I think that they're included in PD because the experience is, in important ways, qualitatively similar to that of psychedelic drugs. Again, then, drugs which produce cannabis-like effects belong in CD.
Some CDers don't like synthetics- I'm sure that some PDers don't like dissociatives. They are free to not post in those threads.
Finally, the suggestion that we can't give good HR advice in CD...that's verging on being offensive to be honest. Sorry that we're not as worldly and helpful as the bods over in PD. I think we can manage "start with a low dose...use a milligram scale...don't do too much". We're not stupid.
