Former UK drug czar David Nutt (and author of the amazing and indispensable Drugs Without the Hot Air) has published a paper in the journal Nature Reviews Neuroscience called "Effects of Schedule I drug laws on neuroscience research and treatment innovation" where he, and his co-authors (Leslie A. King and David E. Nichols) call modern drug policy "the worst case of scientific censorship since the Catholic Church banned the works of Copernicus and Galileo." The Independent summarises the paper:
The paper, which is published to coincide with a conference on scientific research with psychedelics at Imperial College London, points to evidence that cannabis, MDMA and psychedelics such as LSD and psilocybin (the compound found in magic mushrooms) have unexplored medicinal benefits and argues that laws should be updated.
Small clinical studies of MDMA, which was originally used in the USA in the 1970s to improve communication in psychotherapy sessions, suggested that it could play a highly beneficial role in the treatment of PTSD patients. The paper’s authors said the drug could also help with “end of life anxiety” and couples therapy”.
Medical use of marijuana is already legal in 17 US states, and the drug has been shown to have benefits such as anxiety reduction and pain relief. However, Professor Nutt said that UK restrictions had blocked development of therapeutic applications for any of cannabis’ 16 active ingredients.
LSD, meanwhile, was widely researched in the 1950s and 1960s, with more than 1,000 papers investigating outcomes for more than 40,000 patients, with evidence suggesting that the drug might be an effective treatment for alcoholism, before bans on the drug around the world ended further research.
