Hehehe yeah!
Well I think Neem is one very likely cause, but if we think logically for a second, we have to admit that there could possibly be more than one cause. CHS is just "vomiting like crazy", and a lot of things could cause that. It seems that some people experiencing these unpleasant symptoms are reacting to Azadirachtin in bud that was grown with Neem. Because heavy vomiting is one of the main symptoms of Azadirachtin toxicity (poisoning). Totally explains it. But there could also be some other people with similar symptoms, that aren't reacting to Neem, but perhaps some other substance (either from the cannabis or from products used in its production).
I would love more research of all kinds to be done on this topic! If we keep the politics and moral discussions out of it, and just focus on the biology and chemistry, we should be able to get to the bottom of this.
Something tells me CNN and friends aren't interested in the truth, but in just continually demonizing cannabis, to continue to prop up their overlords (big Pharma). So these stories will probably continue. Did you notice, they claimed you can DIE from the vomiting? Come on. That's like saying you can die from peeing. If you pee too much, you'll get dehydrated! And if you get dehydrated, you might go into shock. And if you go into shock, you need medical care, or you might DIE! Ooooooh. But dying from peeing really just doesn't happen. Same thing with dying from puking. They just want to ramp up the fear an extra notch. Bastads.
