Graham Hancock - Hancock gave a
TEDx lecture titled "The War on Consciousness", in which he described his use of
ayahuasca, an amazonian brew containing a hallucinogenic compound
DMT, and argued that adults should be allowed to responsibly use it for self-improvement and spiritual growth. At the recommendation of TED's Science Board, the lecture was removed from the TEDx YouTube channel and moved to
TED's main website where it "can be framed to highlight both [Hancock's] provocative ideas and the factual problems with [his] arguments".
