I am glad that people are trying to have a rational conversation about drugs.

Your decision to place your law enforcement resources in these communities is racism, but nobody has called people out on this. The law itself is not racist. But people's decision about where we're going to place our efforts, who we're going to prosecute, who we're not going to prosecute, is racism. And nobody's calling them on it.

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.

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.

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