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.

A lot of addiction actually ends by age 30 - something like 50 percent of all addictions with the exception of tobacco - and I think a lot of what's going on there is that the self-control areas of the brain are finally developed enough to be able to stop yourself from relapsing or just continuing. There is a maturational aspect to it as well.

The thing about our drug laws is that they're not based on science.

In order for people to recover, we can't just say 'love is all we need.'

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

Drug warriors' staunch opposition to needle exchanges to prevent the spread of HIV in addicts delayed the programs' widespread introduction in most states for years. A federal ban on funding for these programs wasn't lifted until 2009. Contrast this with what happened in the U.K. At the peak of the AIDS epidemic in the mid-1990s, the HIV infection rate in IV drug users in the U.K. was about 1%. In New York City, the American epicenter, that figure was 50%. The British had introduced widespread needle exchange in 1986. That country had no heterosexual AIDS epidemic.

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.
