> I don't drink coffee. And even if I did, caffeine is not a drug that spreads to others in the air they breathe.

No, it's much more insidious. It amps people up like crack cocaine or methamphetamine. It's a real killer--people have died from it. That's why the U.S. military absolutely bans caffeine use during basic training, for example. It's a really dangerous drug that should be controlled. The people pushing this poison should be behind bars. Think of the children.
