Our society values alert, problem-solving consciousness, and it devalues all other states of consciousness. Any kind of consciousness that is not related to the production or consumption of material goods is stigmatized in our society today. Of course we accept drunkenness. We allow people some brief respite from the material grind. A society that subscribes to that model is a society that is going to condemn the states of consciousness that have nothing to do with the alert problem-solving mentality.

Most of the so-called illegal drugs have vastly increased in use, despite billions of dollars spent suppressing them. I believe 750,000 Americans are arrested every year for possession of cannabis. I mean that's 750, 000 lives damaged by that arrest process. It's a crazy, crazy system. It's playing into the system that the hallucinogens are grouped together with addictive drugs, which they are not. But addictive or not it's our responsibility as adults to make decisions and it's not the states' right to do that, in my opinion.

Science has often resisted new ideas and fought bitterly to prevent them coming on board.

My sense is that we are missing a huge part of the human story. I think it's possible, indeed probable, that we are a species with amnesia; that we've lost the record of our story going back thousands of years before so-called history began, and I think that if we could go back to that dark epoch, we would discover many astounding things about ourselves.

Just plain logic says that the war on drugs does not work. It absolutely does not work. We have this highly addictive legal drug called tobacco which has never resulted in people being sent to prison, but there has been a massive reduction in its consumption simply because responsible adults looking at their own bodies have said they don't want to do that to themselves.

Human history has become too much a matter of dogma taught by 'professionals' in ivory towers as though it's all fact. Actually, much of human history is up for grabs. The further back you go, the more that the history that's taught in the schools and universities begins to look like some kind of faerie story.

There are all kinds of ways to challenge ourselves. Some people do it by climbing a mountain or scuba diving. The most profound and challenging ordeals is to drink Ayahuasca. It is in a way the ultimate adventure.
