Unfortunately I tried the real "cocaine" in the past. Not my thing. Who the hell wants to be so wired...even if its a whole load of caffeine.
Being wired is one thing, jonesing ever 15 minutes is a real b----. That depression over time is what made me stop. I can't stand complete and utter loss of dopamine and serotonin (I can't remember which exact one is surged through the brain with cocaine), especially in stark contrast to having just been doused with them.
But a manufactured high now would drive me nuts. My head and mouth are naturally in overdrive. I can't even imagine.
