I agree with all that.
The way they are being distributed atm (wont get specific at all, just general commonalities), is no up front warnings about how dangerous nbomes are compared to other psychs, physically, which you see very little of in the tried and true classics. This information lacking, and the impersonal way in which its sold, leaves plenty of room for unprepared/responsible hands to get a hold of the stuff, and that's prob the reason you get these issues unfortunately, IMHO. :|
Coupled for their ability to be the least confrontational psychs, (at lower doses, relative to something that isn't as cushy/recreational like the classics seem to be), ends up with people getting a false sense of security about them, not realizing the physical danger, and dose irresponsibly high. Thinking its just going to be a better version of what they got at a lower dose.
Not a trip to the emergency room, or worse. In terms of what can go wrong PHYSICALLY. In simpler terms, the tried and true (lsd, dmt, psilo, aya, cactus, etc) wont do that unless you take a a ridiculous overdose. But they are far from recreational at large doses imho, unlike the nbomes.
See the problem?
Just some ideas i have about why people die from rcs, when deaths from the classicals are much rarer. Not talking psychological stuff, suicide, psychotic violence, etc. Just that you could die simply from a large (but not ridiculous) dose of a psych that leaves a false impression of light physically/mentally, when in fact that holds true for high doses as well with nbomes. The crazy stuff just like you get from most of the other psychological psychadelic induced breakdowns over the decades.
And the people using them, i wont speculate on how educated they are/research what they take, but possibly if the distribution allowed for these type of people to easily acquire them, its a recipe for disaster.
