Hippy hippy fake

Why getting ‘high’ on LSD may just be placebo effect

IT was the drug of choice for hippies looking to turn on, tune in and drop out during the late Sixties.

But LSD may not have been as mind-blowing as many revellers who took it believed, researcher­s claim.

A study has found that those given a placebo – an inert tablet such as a sugar pill – can be persuaded they are undergoing the same mind-bending experience as they would if they had taken hallucinog­enic drugs such as LSD or magic mushrooms.

It means some who believed they had ‘taken a trip’ may have felt high due merely to the atmosphere of the party or event they were at. The same may apply to the ‘ rave’ drugs taken at acid house parties in the Eighties and Nineties.

The research, by scientists at McGill University in Montreal, suggests that ‘trippy’ experience­s can be brought on by the expectatio­n you are about to get high.

To test whether psychedeli­c effects could be induced by a placebo, Canadian researcher­s gave 33 volunteers – who believed they were taking part in a study of the effects of drugs on creativity – the fake LSD at a four-hour psychedeli­c party with DJ, colourful paintings and light show.

To convince participan­ts they had been given a hallucinog­enic, there were ten whitecoate­d staff, a security guard and several actors who behaved as though they had taken a psychedeli­c substance.

When asked near the end of the study, 61 per cent of the volunteers reported some effect of the drug, ranging from mild changes to symptoms resembling taking a moderate or high dose of an actual drug.

Several of the volunteers said they saw paintings on the walls ‘move’ or ‘reshape’ themselves. Others described themselves as feeling ‘ heavy... as if gravity [had] a stronger hold’, and one described having a ‘come down’ before another ‘wave’ hit her.

Several were certain that they had taken a psychedeli­c drug.

Samuel Veissiere, a cognitive anthropolo­gist who teaches at McGill’s Department of Psychiatry and supervised the study, said: ‘These results may help explain “contact highs” in which people experience the effects of a drug simply by being around others who have consumed it.

‘More generally, our study helps shed light on the “placebo boosting” component inherent in all medical and therapeuti­c interventi­on, and the social influences that modulate these enhancing effects.’
