Erm, not really
How do you think one becomes a junkie ?
This message just doesn't seem to reach people does it? Each junkie would've said to themselves, "It's okay, I can handle it. I can quit whenever I like", until one day the drug takes control. People don't have a choice, when it decides to control you, it does. Not the other way around. There are many so-called "recreational drug users" who think they are in control, but I'm willing to bet they are unable to stop using. Just because they are not behaving in the same way as Cousins, doesn't mean they don't have a drug problem.
