> Hart reports that more than 70 percent of drug users—whether they use alcohol, cocaine, prescription medications, or heroin—do not meet the health criteria for drug addiction.

I don't think it's about health criteria. It's about whether you want to add yet another item to things you depend on just to feel normal.

Also, the need is a symptom of a real issue that needs to be addressed instead of just numbed and berried i.e., unhappy at a job or a situation etc that needs to be addressed.
