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.

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

I've had investigations of my lab because people didn't like what I had to say. And when you have investigations and you're doing research, you're shut down for a while. You have to start all over again. So that's one area where I paid a high price.

When you have the national narrative being "crack is awful and black people are using it," why go against that narrative when you want to get that publication in The New York Times or wherever? It encourages people to play right into it.

You have rappers saying "stay off drugs, go to school" - empty verbal behavior. I think all of this became institutionalized in the early '90s. And it's become more and more solidified, more and more entrenched.

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.
