The biggest problem I have is that the nxxx substances are being touted as the same as lsd. Then naive people over dose because they are told it is "a better LSD mimic" when in fact that is not the case. If people want to use drugs responsibly that's their business and should be free to do so.
However, posting misleading statements on forums is as equally irresponsible as misrepresenting something for sale or given away for free; it is a dangerous practice that could potentially cause harm.
I don't know what makes one compound more or less visual than another (if I did though you would have incorrectly assumed something about me!). I will call someone out though if they claim:
"But to a novice to hallucinogens, it's much more likely to pass as lsd. This is because everyone expects visuals, and it gives you plenty. And it kicks in at a suitable time, rather than after 2 hours and peaking at 6 hours."
Because this is a morally bad statement to make.
For christ sakes, if we keep calling the drugs we so adore "hallucinogens" and trying to pass them off for LSD... then yeah, the ban hammer of law is going to come down, and the people who need to stay on the right side of the law will be forced towards even newer and less researched chemicals, with no documented safety profiles. Is this a good idea?
Also why should people expect super crazy visuals on LSD? it's because of all the (anti-drug) propaganda which deliberately fails to accurately surmise what a LSD (or psychedelic in general) experience is. Why then, should we, as the supposedly enlightened, continue to propagate information which was originally intended to undermine the very things we enjoy? (rhetorical)
