Thanks @kaliberlin for the excellent article. google 'Breaking Convention', the bi-anual conference on all things psychedelic held at Greenwich, England where you will meet old and young hippies rubbing shoulders with psychiatrists, neuroscientists, philosophers, shamen, artists, lawyers, police chiefs, journalists, acid chemists, pot farmers, musicians, yogis, scholars, comics, ethnologists and other interested parties. lots of videos from this conference are available on vimeo.
