If you're a member of a despised group, look out! They'll find a drug and associate you with its use. There are a lot of people in the gay community using methamphetamine and paying taxes and going to work and doing well.

Looking at the data and at my drug use and evaluating it carefully just let me see that I wasn't special, but my drug use challenged what I thought about cocaine. Because I would accept when I would say, "What happened to that person?" and someone would say, "They started using cocaine...they went downhill..." I would just accept that, even though I had a different experience and all these other people had a different experience. But I would throw that out because I thought my experience was an aberration.

My critique of how we deal with drugs in society is just that - that we use these anecdotes to apply to everyone and the anecdotes are not representative.

Our ability to study the brain has been limited because of our tools and our tools have only allowed us to look at one neurotransmitter and we haven't looked so much into co-localization and co-release of transmitters. Our thinking is hampered by our tools.

If we want to think about racism and how it might play out in drug policy, we have to think about the trial of George Zimmerman. We think about the prosecution, when they said "race is not a factor." It's so dishonest.

Writing in a nuanced way, getting at all the details in a way that remains interesting for the reader, is very difficult.

I have three boys. And I wanted to make sure it connected with them and then those guys who grew up like me, in environments like me.And then I knew something about science that your New York Times reader would be interested in. So I was thinking about it in multiple ways: I'll connect with the people who grew up like me first, and then the New York Times reader will be interested in the science because it's so good and they want to be "in the know."
