Seems like if one would get enough of that stuff you could turn into The Unibomber .......... or Al Gore (without the Häagen-Dazs).
I remember back in the 70s/80s, a number of companies started producing legal, caffeine-based "knockoffs" of popular amphetamines (Black Beauties, etc.). The imitators weren't nearly as strong (or addictive) as actual speed, of course, but a lot of kids took them for a cheap rush. I'm sort of wondering if the 100 pack option is catering to that niche.
LOL .......... I hate to admit this ...... but what the heck ............ my wife and I used to be house painters way back then (worked for the very coolest and highly respected interior decorators).
Anyhow, we knew some shady characters back then , we got a great deal and bought a very big plastic container of (I think 1000) those black beauties....... to help us get through the rigors of the days of painting.
They certainly worked well, but one odd thing happened every once in a while to me ............. after I'd have one in the morning, every once in a while my upper lip would "blow up" ....... sorta like getting hit by a jab from Cassius Clay.
It happened about a dozen times ......... then we decided never to get them again!
