Volunteers given LSD to aid research.
A GROUP of 20 British volunteers are the first in the world to have had their brains scanned while high on LSD.
The controversial study, which took place at Cardiff University and finished this year, was co-led by ex-drugs tsar Professor David Nutt.
Prof Nutt was sacked from his job as the Government's chief adviser on drugs in 2009 after saying ecstasy and LSD were less harmful than alcohol.
At a briefing in London he spoke out against restrictions on research on recreational drugs which he called "the worst censorship in the history of science".
Having been turned down by "classic funders" he is now campaigning to raise the PS25,000 needed to carry out analysis of the brain scanning data from walacea.com - the science crowdfunding site.
The LSD study involved giving the volunteers injections of a 75 microgram dose of LSD before probing the activity of their brains.
Two kinds of scans were used, functional magnetic resonance imaging and magnetoencephalo-graphy which measures small magnetic fields.
None of the participants reported having a bad experience but three described some anxiety and temporary paranoia.
Dr Robin Carhart-Harris said the dose of LSD given to the volunteers was a "tiny speck", but added: "The effects are quite profound. It would be described as a moderate dose but a moderate dose of LSD can still produce a profound state of consciousness."
