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.

We should decriminalize all drugs. The assumptions on which our drug policies are based are flawed.

We need to continuously put pressure on politicians to do more, because they are happy just to do nothing—it’s easier to do nothing.

One of the things that has happened is that our drug laws have been institutionalized now. If you want to say that somebody's a bad person in a movie or in a television show or something about that, you say they sell drugs or they use drugs.

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.

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.

The way we're currently educating people about heroin is to say that heroin is so awful. Heroin is not so much the problem. It's when you combine it. It's hard to die from heroin alone.
