A lot of the stuff that we say about drugs is just wrong.

I think our drug laws need to be made scientifically, as best as possible, recognizing that values will always be part of that.

I also had my own addiction to cocaine and heroin in my 20s. I knew that it was driven not by the things that the drug workers were telling me; in fact, I couldn't believe any drug information that was given to me by authorities because I knew from my own experience that it was wrong.

When President Nixon declared war on drugs on June 17, 1971, about 110 people per 100,000 in the population were incarcerated. Today, we have 2-3 million prisoners: 743 people per 100,000 in the population. The U.S. has 5% of the world's population, but 25% of its prisoners. As Senator Jim Webb once put it, Either we are home to the most evil people on earth or we are doing something different and vastly counterproductive.

Because of the war on drugs, pain patients are treated with skepticism and pain doctors live in fear of being prosecuted for overprescribing. The end result is that addicts still get their opioids without much trouble, while genuine patients often can't find treatment. Those who do must typically be tracked in a database and must schedule frequent, expensive doctor visits for surveillance like urine testing.

Punishment by definition isn't going to help. So what you need to do is to help people to change and recover is to help them find different areas of passion and help them find better ways of coping. Because about 50 percent of people with addiction have a preexisting mental illness, about two-thirds have had some type of severe trauma during childhood, and they are not using to the point where they're risking their lives because it's fun. They're doing something to help them cope.

There's traditionally been two different ways of seeing addiction. Either it's a sin and you're a horrible bad person and you are just choosing to be hedonist or it's a chronic progressive disease. And while I certainly believe addiction is a medical problem that should be dealt with by the health system, the way we've conceptualized addiction as a disease is not actually accurate, and it has unfortunately become stigmatizing and it's also created a lot of hopelessness in a lot of people.
