Some drugs are inward drugs. LSD, you can have an incredible life-changing experience sitting cross-legged in a dark room by yourself for 12 hours. Heroin, you just sink into a couch and feel incredible. Pot, you gain a new appreciation for loony toons.
Coke is not one of those drugs. Cocaine is an outward drug. It takes outside stimulus (specifically OTHER PEOPLE) to make it worth your while. All my most memorable "inward drug" experiences are crazy things I would never have dreamed without the drugs. All my most memorable coke moments are shit that could've happened without drugs, but probably wouldn't have. Cocaine as a drug is pretty weak; cocaine as an experience is where the fun is at. Anyway, my point is that you can't bash the drug just because you weren't impressed with the high, because it's not the high that's impressive (though I do know a girl who CRIED the first time she came down off coke because she was so sad the high was leaving).
Also, I think the article does more harm than good. It overstates the addictive quality of cocaine--it makes it seem like one gram of it and your an addict. Overstating the dangers of a drug is the most dangerous, yet most common, tactic to discourage people. Once a person tries a drug, and they get past the "danger zone" they were warned about without any trouble (in this case 1 single gram) , they realize they were lied to and get lulled into a false sense of security. The reality is they weren't lied to, they were misled. And by the time they finally figure that out, it's too late.
