Oh gosh, I've seen enough people use cocaine that I wouldn't call it a "mild" stimulant by any stretch of my imagination. It's basically a stronger form of caffeine.

One friend of mine with severe ADHD turns completely normal on it. Everyone else that I've seen use it becomes an asshole. I'm pretty open minded about letting adults choose what they want to do with their bodies, but I don't like being around people using coke.

Edit: If it wasn't for the cardiac issues, I'd wonder if it would make a better ADHD medicine.
