According to Joseph O’Callaghan’s letter (Irish Examiner, August, 25), “people who smoke or eat cannabis have fewer of these little cancer fighters (T lymphocytes)”, implying they are more prone to cancer.

However, research documented on the UK Medicinal Cannabis Project web site(www.medicinal indicates that cannabis may help protect against the development of some tumours.

To quote from the web site: “One study examined the effects of delta 9 tetrahydrocannabinol (THC), delta 8 THC and cannabinol on cancer cells in mice lungs. Researchers reported that cannabinoids reduced the size of the tumours by 25 82%, depending on dose and duration of treatment.”

Similar findings have been made with respect to breast cancer.
