I have no trouble with RC benzos in general. Some were even specifically useful for medical use and not much else - pyrazolam and diclazepam. But I think selling the ridiculously potent ones was a bad move. Clonazolam and flubromazolam in particular would never have been put on sale if I was a vendor. I'm honestly shocked the tabloid media never picked up on them.
The most dangerous RCs are those synthetic cannabinoids. Crazy addictive, horrible side effects, horrible withdrawal. I've seen them drive people crazy and you don't even know what's in them half the time. Usually some bullshit that should be dosed at microgram levels but is instead sprayed on random herbs and sold as "Ultra Funky Lizard Spice Incense."
But the RC scene is not dead and buried at all. The cannabinoids are still going to be sold by dealers as there's a lucrative market for them. The benzo scene isn't going anywhere either, although the exact benzos on sale will change. The RC stims will just be sold as cocaine.
