Cannabis Conundrum

Young people who regularly combine cannabis and tobacco face nearly three times the risk of developing a full psychotic disorder. That is the central finding of a landmark study published in Nature Mental Health, and it is one that researchers say demands urgent attention. Dr Heather Ward at Vanderbilt University led the research. Her team

New research from King’s College London asks one of the most pressing questions in mental health science: why does cannabis use raise the risk of psychosis in some people but not others? Scientists published the findings in Biological Psychiatry: Global Open Science in 2026. They point to a complex web of shared genes and biological pathways

Cannabis is the most commonly used illicit substance during pregnancy. Many pregnant people are unsure of the risks or where to turn for support. Researchers are exploring practical, accessible ways to help expectant mothers reduce or stop use. One of the most promising approaches may be as straightforward as putting on a pair of trainers.

The Road Danger Nobody Is Talking About For decades, the conversation around drink driving has dominated road safety campaigns.

Therapy, Not Tablets: The Real Picture of Cannabis Addiction Treatment The most comprehensive scientific review of its kind has found that no medication works for cannabis addiction treatment, while certain talking therapies offer more meaningful promise. The findings come from the journal Addiction, published in 2026, at a time when cannabis use disorder is rising worldwide

A sweeping new study published in The Lancet Psychiatry has reignited a long-running debate about medical cannabis for mental health conditions. The findings make for uncomfortable reading for a fast-growing private prescribing sector that has largely outpaced the science behind it. Researchers described this as the largest and most comprehensive review of its kind. They analysed

On 25 March 2026, the International Academy on the Science and Impact of Cannabis (IASIC) hosted a presentation by Dr Ragy R. Girgis, M.D., M.S., Professor of Clinical Psychiatry at the Columbia University Department of Psychiatry and the New York State Psychiatric Institute. His subject was cannabis and mass shootings, and the findings come from

A major new study has found that cannabis memory loss goes further than most people expect. Smoking cannabis does not simply blur memories. It can actively distort them, creating false recollections of things that never happened. Washington State University (WSU) researchers say THC, the psychoactive compound in cannabis, disrupts the brain’s ability to store, retrieve,
