Medical cannabis gave relief of symptoms ranging from chronic pain to insomnia with relatively few negative side effects, according to a new study.
Users reported a four point reduction in symptoms – on a 1-10 scale – in a study of 27 different health conditions.
The conditions ranged from seizure disorders to depression and those taking part in the study used a variety of cannabis products.
A second study focused on using cannabis flower or ‘buds’ to treat insomnia and produced similar results.
Both studies were carried out at the University of New Mexico.
“If the results found in our studies can be extrapolated to the general population, cannabis could systematically replace multi-billion dollar medication industries around the world,” said Prof Jacob Miguel Vigil of the Department of Psychology.
The studies analysed data collected with the Releaf App, an educational software programme designed to record individual cannabis use and the corresponding change in symptom intensity.
More than 94pc of cannabis users reported a reduction in symptom intensity.
Users said the felt more positive – relaxed, peaceful, comfy – with a small percentage feeling paranoid, confused or having a headache.
The longer-term therapeutic potential of substitution of cannabis for traditional pharmaceuticals “could reduce the risk of dangerous drug interactions and the costs associated with taking multiple medications” said Prof Sarah Stith at the University Department of Economics
The studies are published in the journals Frontiers in Pharmacology and Medicines.
