I used to do drugs, but that was way back there.

I was a cool person at one time. I used to do cocaine.

If Someone had brought me drugs, I would have taken them.

I know this is not a very popular idea. You don't hear it too often any more … but it's the truth. I have taken drugs before and … I had a real good time. Sorry. Didn't murder anybody, didn't rape anybody, didn't rob anybody, didn't beat anybody, didn't lose – hmm – one fucking job, laughed my ass off, and went about my day. Sorry. Now, where's my commercial?

I am an unapologetic drug user. I take drugs as part of my pursuit of happiness, and they work. I am a happier and better person because of them. I am also a scientist and a professor of psychology specializing in neuroscience at Columbia University, known for my work on drug abuse and addiction. It has taken me more than two decades to come out of the closet about my personal drug use. Simply put, I have been a coward.

I took drugs on several occasions at social events more than 20 years ago. At the time I was a young journalist. It was a mistake. I look back and I think I wish I hadn't done that. I think all politicians have lives before politics. Certainly when I was working as a journalist I didn't imagine I would go into politics or public service. I didn't act with an eye to that. The question now is that people should look at my record as a politician and ask themselves, 'Is this person we see ready to lead now?' I have seen the damage drugs can do to others and that is why I deeply regret the decisions I took,

I suppose I’ve been knocking on heaven’s door for about 11 years now, with one sort of high or another. The only kinds of drugs I use, though, are ones that keep me working for longer periods of time. I haven’t gotten involved in anything heavy since ’68. I had a silly flirtation with smack then, but it was only for the mystery and enigma of trying it. I never really enjoyed it at all. I like fast drugs. I’ve said that many times. I hate falling out, where I can’t stand up and stuff. It seems like such a waste of time. I hate downs and slow drugs like grass. I hate sleep. I would much prefer staying up, just working, all the time. It makes me so mad that we can’t do anything about sleep or the common cold.

I grew up in the hood. And so, when we think about these communities that we care about, the communities that have been so-called devastated by drugs of abuse, I believed that narrative for a long time. In fact, I’ve been studying drugs for about 23 years; for about 20 of those years, I believed that drugs were the problems in the community. But when I started to look more carefully, started looking at the evidence more carefully, it became clear to me that drugs weren’t the problem. The problem was poverty, drug policy, lack of jobs—a wide range of things. And drugs were just one sort of component that didn’t contribute as much as we had said they have.

I had a drug problem. I'd go to parties, take a leak, and there was cocaine right there. I was 25 when it started, rich, famous, and retired.

People use drugs, legal and illegal, because their lives are intolerably painful or dull. They hate their work and find no rest in their leisure. They are estranged from their families and their neighbors. It should tell us something that in healthy societies drug use is celebrative, convivial, and occasional, whereas among us it is lonely, shameful, and addictive. We need drugs, apparently, because we have lost each other.

You realize that people take drugs because it's the only real personal adventure left to them in their time-constrained, law-and-order, property-lined world. It's only in drugs or death we'll see anything new, and death is just too controlling.

He did some drugs at university," I said. "Isn't that what it's for?

In my teens my drug of choice was acceptance, in my twenties it was approval, in my thirties it was love, in my forties it was Scotch. That lasted a while,’ she admitted. ‘Now all I really crave is a good bowel movement.

I don't do drugs, nor have I ever believed in them. Am I a creative person? Then why do people think in order to be creative one must do drugs? Actually, I think people take them as an excuse to screw up in public, y'know, spill things or get silly. Drugs have slowed down civilization because we have to wait for people to get off their high before we can resume. They are the millstone around society's neck.
