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.

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.

It may be that DMT makes us able to perceive what the physicist call "dark matter" - the 95 per cent of the universe's mass that is known to exist but that at present remains invisible to our senses and instruments.

You have to understand that we've had more than 40 years now of massively financed propaganda called the 'War on Drugs'.

I see myself as a journalist reporting neglected stories about our past and trying to bring rigor, reason and intuition to the quest.

We live in a society that will send us to prison if we make use of time-honored sacred plants to explore our own consciousness. Yet surely the exploration and expansion of the miracle of our consciousness is the essence of what it is to be human? By demonstrating and persecuting whole areas of consciousness, we may be denying ourselves the next vital step in our own evolution.

I believe we are a species with amnesia, I think we have forgotten our roots and our origins. I think we are quite lost in many ways. And we live in a society that invests huge amounts of money and vast quantities of energy in ensuring that we all stay lost. A society that invests in creating unconsciousness, which invests in keeping people asleep so that we are just passive consumers or products and not really asking any of the questions.
