Scientists find little evidence to show cannabis oils help end pain, according to major study

  • Many ads for CBD imply pain relief, but most are classified as dietary supplements
  • CBD sold in stores in the UK must not contain more than 1mg of cannabinoids, such as THC
  • dr. Amir Englund said: ‘There is almost a complete lack of well-designed studies’
  • Cannabis products have become a £700m a year business in the UK

Trendy cannabis-based products that have hit UK sales of £700m a year don’t seem to ease the pain, according to a major US study.

Over the past decade, sales of oils, sprays, and ointments containing cannabidiol (CBD), one of the main active ingredients in cannabis, but which do not cause the “high” associated with the class B drug, have increased over the past decade. exploded.

Many advertisements for CBD products imply health benefits, including pain relief, although the makers are prohibited from making explicit claims as almost all of them are classified as dietary supplements. But researchers have now found little evidence in a US government-backed study that they help in this regard.

In the journal Annals Of Internal Medicine, author Professor Marian McDonagh of Oregon Health and Science University wrote: “With so much buzz around cannabis-related products and the ready availability of marijuana in many [US] states, consumers might assume there would be more evidence about the benefits and side effects. Unfortunately, there is little scientifically based research on most of these products.’

The researchers found that products very high in tetrahydrocannabinol (THC) – the psychoactive compound in cannabis that causes the ‘high’ – seemed to help chronic pain, at least in the short term, although patients taking them often experienced drowsiness and nausea .

However, CBD products sold in stores in the UK cannot legally contain more than 1mg of legally controlled cannabinoids such as THC. For a 30 g bottle of CBD oil, that corresponds to about 0.003 percent THC.

dr. Amir Englund, of the Institute of Psychology, Psychiatry and Neuroscience at King’s College London, said: ‘There is almost a complete lack of well-designed studies’ on cannabis products for pain relief and few had tested the products with a placebo.
