I could definitely understand benzedrine, and could sort of understand it at a stretch, if it was the decongestant stimulant pseudo-ephedrine. I wasn't really congested when I took it, or if I was it was only as a result of sniffing other stims, IIRC.
But it did seem to clear my sinuses, and it worked pretty decently as a stimulant too I thought, and it was better than I had been led to expect. Maybe pseudo works great for some people.
Subsequent doses haven't hit me as well though.
I think it's another of those things that you have to take once in a blue moon to get anything resembling good, useful, or decent effects.
The video looks like shoddy and lazy reporting, based on the title and description though. By the sounds of it, people aren't becoming physically or mentally addicted, they're merely attempting to avoid 're-bound congestion' and develop a "dependence" on the spray as a result.
It was probably a slow news day.
