In a criminal justice setting, it's very hard to create a therapeutic environment where people do feel safe, but the real important thing to do is to do your best to do that.

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

We have a system that was devised by racists to create racist ends.

Do we really want to base our 21st-century policy on what the colonialist preferred at a certain time in history, not at all based on health or what the preferences of different cultures might be? That's just ridiculous.

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.

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.

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.
