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.

I know that sounds really extreme, but if you just look at the history, you will find Harry Anslinger [first U.S. commissioner of the Bureau of Narcotics] going on about satanic swing and how reefer will make black people think they're as good as white people - which to him, obviously, was a very horrible outcome. This is the basis of our drug laws.

Love is great and it does help a lot of people, but a lot of people do have things like depression or schizophrenia or bipolar disorder or other disorders, all of which will need to be addressed in order for people to stay in long-term recovery.

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.

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

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.

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.
