Cancer patients who used a cannabis mouth spray had their level of pain reduced by 30 percent, a study has shown, according to BBC.
The cannabis based spray, administered like a breath freshener, was tried on 177 patients by researchers from Edinburgh University in Scotland.
Patients in the study had not been helped by morphine or other conventional medications.
The spray was developed so that it did not affect the mental state of the patients in the way that using cannabis would, BBC reports.
The researchers were quick to hedge on their findings, reported in the Journal of Pain and Symptom Management, saying that the study didn’t justify smoking marijuana “as this could increase the risk of cancer.”
They evidently had spent so much time conducting their own study, they didn’t read the available literature. Multiple studies have shown that cannabis in fact contains anti-cancer agents.

Scientists said the spray worked by activating cannabinoid receptors, which can stop nerve signals being sent to the brain from the site of the pain.
The spray, marketed under the brand name Sativex, differs from the “pot pill” Marinol, which contains only tetrahydrocannabinol (THC), one of the cannabinoids in marijuana. Sativex, by contrast, contains both THC and cannabidiol (CBD), in an almost equal mixture.
“These early results are very promising and demonstrate that cannabis-based medicines may deliver effective treatment for people with severe pain,” said Professor Marie Fallon of the Edinburgh Cancer Research Centre at Edinburgh University.
