From my personal observations, I don't think coke is quite comparable to heroin. Heroin takes over a person's life in a much more scary way than coke. Heroin becomes the number one thing every day, before food, family, or any other concern. Granted, you can easily be a high functioning heroin addict, if the expense and acquisition are not concerns, but at a point, heroin merely makes you 'normal', and even slightly outside that window is a steep descent into withdrawal hell.

Coke is both better and worse. Not quite as addictive, but it seems to damage people more than heroin does (particularly mentally).

Isn't it only 10% of heroin users that become addicts?

Source? I know a few people who tried but did not become addicted, but i thought of them as more of an exception.
