Cannabis, cannabinoids and cancer – the evidence so far

At the moment, there simply isn’t enough evidence to prove that cannabinoids – whether natural or synthetic – works to treat cancer in patients, although research is ongoing. And there’s certainly no evidence that ‘street’ cannabis can treat cancer.

Evidence on cannabis and cancer

We do know that smoking is unhealthy.  And that, like tobacco, cannabis contains cancer causing substances. Therefore it would seem likely to increase cancer risk. But we need more research to know this for sure.

Why researching cannabis is difficult

There are difficulties in researching the effects of cannabis.

  1. Many people who smoke cannabis also smoke tobacco. And users of cannabis often mix it with tobacco. This can make it difficult to know whether it is the tobacco, the cannabis, or both that has caused a cancer.
  2. The amount of THC in cannabis also varies. Some of the cannabis available today is much stronger than it was 20 years ago. These versions contain more THC.
  3. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research. And if they do agree to take part, they may not say how much cannabis they actually smoke.
