UK Scientist David Luke, senior lecturer in Psychology at the University of Greenwich,(London) has spent years investigating the effects of psychedelic drugs and believes some may hold the key to curing a number of diseases.

Speaking to Daily Star Online, he revealed why he thinks drugs such as MDMA (a purer form of ecstasy) and psilocybin (a naturally occurring chemical found in magic mushrooms) will be legalised.

Research has been carried out at John Hopkins University in the US, testing out MDMA as a cure for post-traumatic stress disorder (PTSD) and magic mushrooms to treat depression.

He said: “We’re moving to the point where psilocybin and MDMA are being put through clinical trials.

“They will likely get licensed and therefore reclassified as drugs for medical purposes.”

He said the research at John Hopkins “has been successful, particularly with the use of psilocybin to treat depression.”

And Dr Luke — whose book Otherworlds came out last year — had some ground-breaking revelations on when these drugs may be legal.

“It could be in the next 10 or 20 years when we see these drugs licensed and reclassified,” he said.

Dr Luke argued the time has come to legalise drugs such magic mushrooms and LSD which have “psychoactive” properties.

“The war on drugs has failed,” he said.

“Prohibition leads to black markets. We need a medical, not a criminal approach to drug use.”

And Dr Luke said we should have learnt our lessons about prohibition from the attempts to ban alcohol in the United States between 1920 and 1933.

Dr Luke — who is known as the “Psychedelic Indiana Jones” for his journeys to find psychedelic experiences in the furthest-flung corners of the world — argued our attitude to mind-bending drugs needs to change.

The famous Indiana Jones film franchise saw Harrison Ford travel to dangerous terrains to find rare artefacts.

Dr Luke said: “Psychedelics when used responsibly have great medical potential.”

MDMA was first made in 1912 and became strongly associated with raves and dance music culture in the 1980s and 90s.

In 2009, the UK government’s then-drug policy expert David Nutt was sacked when he said taking ecstasy was safer than riding a horse.
