Click on through for a great discussion about drug addiction with renowned Neuroscientist Carl Hart:

Here is an excerpt:

DR. CARL HART: Well, I come from—as you said, I grew up in the hood. And so, when we think about these communities that we care about, the communities that have been so-called devastated by drugs of abuse, I believed that narrative for a long time. In fact, I’ve been studying drugs for about 23 years; for about 20 of those years, I believed that drugs were the problems in the community. But when I started to look more carefully, started looking at the evidence more carefully, it became clear to me that drugs weren’t the problem. The problem was poverty, drug policy, lack of jobs—a wide range of things. And drugs were just one sort of component that didn’t contribute as much as we had said they have.

AMY GOODMAN: So, talk about the findings of these studies. I mean, you’ve been publishing in the most elite scientific journals now for many years.

DR. CARL HART: Yes. So, one of the things that shocked me when I first started to understand what was going on, when I discovered that 80 to 90 percent of the people who actually use drugs like crack cocaine, heroin, methamphetamine, marijuana—80 to 90 percent of those people were not addicted. I thought, “Wait a second. I thought that once you use these drugs, everyone becomes addicted, and that’s why we had these problems.” That was one thing that I found out. Another thing that I found out is that if you provide alternatives to people—jobs, other sort of alternatives—they don’t overindulge in drugs like this. I discovered this in the human laboratory as well as the animal laboratory. The same thing plays out in the animal literature.
