However LSD is an illegal substance or drug now, before 1971 it was used in many researches, by hospitals and doctors, trying to discover the deepness of the human mind.
In this film the BBC dig down back time in the history of LSD, we can hear both “parts”, the people who reached a “higher” state and initiated the hippie revolution through the US and the UK, and those who think that this is a dangerous drug which should be illegal forever.
From this film many artists had got inspiration and have cut samples, maybe the most noticeable and known is the track LSD by Hallucinogen on the album “Twisted” [Simon Posford's first album]. [Ott's "In Dub" remix can be heard on on two Worlds.Of.Sound mixes -> Entrance Tones, Abstracted Soundfields 2 (the live version from Brixton Academy)],
and the song “Mystical Experiences” by The Infinity Project with Albert Hofmann’s voice [also mixed-in to "Abstracted Soundfields 2].
It is a very well edited documentary with good source of information in this topic.
