I know they're real as I watched my friend pick them up from the pharmacy lol. Real as they get. Sniffing isn't just placebo, its a long standing myth that it is but on the surface of your noses' cappilaries there is some type of interface where the benzodiazepine can be protonated/deprotonated in such a way as to become absorbable nasally. There is heroin that is 2-5%, and it works nasally. I've been doing xanax for over 10 years and believe me, i didnt think they were sniffable before either, but they are. The only benefit is they kick in a bit quicker and can still kick in as quick on an empty stomach. Of course this isnt with whole bars at a time. Im talking 1/4's or 1/3's of bars, split into multiple lines, over the course of 15-20 minutes. That way it gives your nose time to process it. I agree, if you were to crush a whole bar and try to sniff it in one inhalation, that would be both ineffective and stupid.
