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.

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.

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

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.

This beautiful Earth that we have, this gift that the Universe has given us is precious beyond measure, precious beyond imagination, and we are part of it and we must treat it with Love, respect, and reverence.

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.

People think I'm a freemason, and I'm not. People think I believe the end of the world is coming on 21 December 2012, and I don't.
