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

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

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.

Science could never get you to make alcohol and tobacco legal and marijuana illegal. Only racism can do that.

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.

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.
