Can LSD ease our fear of death? First scientific study in 40 years shows positive results

 

Science Editor

Scientists have carried out the first controlled medical experiment in 40 years with the hallucinogenic drug LSD which they used as part of a psychotherapy course to treat severe depression in terminally ill cancer patients.

Volunteers given high doses of LSD – which came to prominence in the hippy culture of the 1960s – showed a 20 per cent decline in their symptoms associated with the extreme anxiety of their medical condition, the researchers found.

The small pilot trial, which involved just 12 men and women, also showed that there were no severe side-effects of lysergic acid diethylamide, the psychoactive chemical commonly known as “acid”. However, their depressive symptoms did get worse when given only low doses of LSD, the scientists said.

“These results indicate that when administered safely in a methodologically rigorous medically supervised psychotherapeutic setting, LSD can reduce anxiety, suggesting that larger controlled studies are warranted,” concluded the study published in the Journal of Nervous and Medical Disease.

Peter Gasser, a psychiatrist based at a private practice in Solothurn, Switzerland, said that all but one of the 12 volunteers enrolled to take part in the trial had never taken LSD before but all of them said that they would take it again and would recommend it to other patients in a similar position.

“All of them said after 12 months of taking the drug that it was worth taking part in the trial and they would come again if asked. They also said they would recommend it for other people in the same position as themselves,” Dr Gasser said.

“We showed that all the treatments were safe and any adverse effects were only mild and temporary – they did not last for more than a day or so. It can be a safe treatment with good efficacy, and it justifies further research with a larger number of people,” he said.

Eight of the 12 patients were given the full dose of LSD, while four were give an “active placebo”, which was a low-enough dose not to cause an effect. The anxiety symptoms associated with depressive illness increased in the low-dose group, who were subsequently offered the high-dose treatment, Dr Gasser said.

A 50-year-old Austrian social worker called Peter, who was one of the volunteers, told the New York Times: “I’d never taken the drug before, so I was feeling – well I think the proper word for it in English is dread. There was this fear that it could all go wrong, that it could turn into a bad trip,”

Each volunteer had two sessions with LSD which they took in a safe, quiet and pleasant room in a private clinic where they could lie on a mattress or sit in an armchair while listening to music, with a doctor in attendance.

“I had what you would call a mystical experience, I guess, lasting for some time, and the major part was pure distress at all these memories I had successfully forgotten for decades. These painful feelings, regrets, this fear of death,” said Peter.

Dr Gasser said that that the patients felt better in terms of their anxiety symptoms about being terminally ill, and the improvement lasted for at least 12 months after the therapy.

“They said in general they felt relief. They felt an intense process of what to do with the rest of their limited time and who they want to spend it with,” Dr Gasser said.

“It’s a period of life when people want to go into a deep psychological process because they realise they don’t have much time left in their lives,” he said.

The last time medical trials took place with LSD on terminally-ill patients was in the early 1960s, before the drug was made illegal in the United States in 1966.

A Swiss scientist called Albert Hoffmann discovered LSD when he synthesised it in his laboratory in 1938 – its psychoactive effects were discovered in 1943.
