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.

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.

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.

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.

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