Psychedelics

Summary & key facts

This is a wide review of classic psychedelic drugs like LSD, psilocybin, and plant mixtures such as ayahuasca. It explains how these drugs work in the brain, how people experience them, and what early clinical research shows about their possible medical uses. The review notes that in carefully controlled settings, single or a few doses can lead to big, sometimes long-lasting improvements in things like low mood, anxiety, and some addictive behaviours. It also says these drugs are not without risks: they can cause intense or frightening experiences and may be unsafe for people with certain psychiatric histories. Overall, the paper calls for bigger, better clinical trials to know how useful and safe these drugs really are.

Key facts:

• Classic psychedelics such as LSD and psilocybin act mainly on a specific serotonin receptor in the brain. This is thought to change how brain regions communicate and can produce strong shifts in perception and thinking.
• Small clinical studies reviewed by the authors found that one or a few supervised doses of psychedelics sometimes produced large and lasting reductions in anxiety and low mood. These effects were seen in people with serious illnesses and in some people with treatment-resistant depression.
• Early trials also suggested psychedelics might help with some addictive behaviours, such as problem drinking or smoking, but the evidence is limited and comes from small studies.
• Psychedelics are not considered chemically addictive like many other drugs. However, they can cause acute psychological distress during the experience, sometimes called a 'bad trip'. That can be risky without proper support and monitoring.
• People with a personal or family history of psychosis or serious mental illness may be at higher risk of adverse effects from psychedelics. The review stresses caution and screening before use in therapeutic settings.
• The paper highlights clear limitations: many human studies were small, the studies were hard to blind (so people knew if they got the drug), and more large, controlled trials are needed to determine how safe and effective these treatments are.
