I find troublesome that the author of the article (renowned neuroscientist and addiction journalist as cited) suggests that addiction is akin to a habit. The behavior itself is certainly habit, but the addiction lies moreso in the etymology and function of the habit than the actual repetitive behavior. For some, the addiction is distraction, for some escape, for others a sense of identity, and so on and so forth. To prescribe "outgrowing the addiction" as a solution is awfully simplistic, almost suggesting that if an addict could only replace that habit with something else, then all would be hunky dory. Well, in theory, sure. Maybe we can start designing rehab centers like they used to do traffic school - Improv Traffic School, Comedy Traffic School, Bikers' Traffic School - maybe Knitters Rehab: "We'll help you put down that needle, and pick up this one!" or Foodies Rehab: "Stop smoking that joint, and learn to smoke these ribs!" The possibilities are endless. But not likely.

This shows drug deaths as comparable to motor vehicle accidents.
(This includes both legal and illegal drugs, and poisoning from prescribed medicine, but I doubt that the rise in recent years is due to worsening quality of healthcare.)
According to the mortality data there would need to be much fewer than 1 million addicts in the 25-44 age range in the US for a majority of them to be dying before they get out of that age group, or even a sizable minority. And everything we know on addiction statistics puts that number much higher, at 10-20 million or more.
The data just isn't there. Addicts aren't going away because they are dying, period.
Some people who get hooked by drugs die, but addiction isn't nearly as deadly as it would need to be for the numbers to drop like they do, and statistically spontaneous remission is the most common way for people to kick the habit. Normally people grow out of it.
