Earlier quoted context omitted.
>80% of people couldn't distinguish I.V. cocaine from I.V. caffeine in some study I am unable to locate at the moment That is complete bullshit.
Curious - do you have something to back that up? Caffeine is pretty toxic ( I think the LD50 is something like 200 mg/KG of body weight. 20 grams would kill most people) and I don't find it surprising that an IV mix would have pretty serious effects.
IV bleach would also have pretty serious effects, but likely no one would confuse it for cocaine.
The onus is on inter_netuser to provide evidence for the claim, not for pennaMann to refute it. I would imagine that literally no study exists comparing the effects of intravenous caffeine and cocaine, because who would possibly fund that study, and to what end, and what review board would approve it?
