A Canadian study of patients seeking medical cannabis to treat chronic pain found that women reported more pain intensity than men and that opioid use was almost halved for those who remained in the study until the end.

“Female sex was significantly associated with worse outcomes than male sex, including pain intensity and pain-related interference,” while opioid use decreased by almost half, from 40.8 per cent at baseline to 23.9 per cent at 12 months, notes the study published in the Canadian Journal of Anaesthesia.

Participants in the observational study — 62 per cent of whom were female, 91 per cent of them white and 88 per cent seeking pain relief — were patients enrolled in community-based clinics in Ontario between Sept. 8, 2015 and July 31, 2018. From questionnaire responses, researchers assessed anxiety, depression, quality of life (QoL), general health symptoms, neuropathic pain, self-reported opioid consumption and adverse events.

To get a full picture, they considered demographics, patterns of cannabis use, long-term effectiveness of cannabis on pain, pain intensity and pain-related interference scores at baseline and three, six and 12 months. Of the 757 people at baseline, that number dropped to 230 at six months and 104 at 12 months.

Time was a “significant factor associated with improvement in pain intensity, pain-related interference scores, QoL and general health symptoms,” the abstract points out.

The researchers acknowledged the significant challenges to collecting long-term observational data on patients who attempted a trial of cannabis products.” Even so, about a third of patients in the study remained on medical cannabis for six months, something that reduced pain intensity and pain-related interference while enhancing QoL and general health symptoms scores.

The findings are consistent with numerous other studies, notes a post from the National Organization for the Reform of Marijuana Laws (NORML).

Study authors noted many study participants switched from consuming herbal cannabis to ingesting oil extracts over the course of the trial, reports NORML. “Beneficial effects of cannabis appear to persist long-term and tolerance may not become a significant issue for patients on a stable regimen,” the blog cites investigators as concluding.

NORML deputy director Paul Armentano views the data from the study to be consistent and persuasive. “For many pain patients, cannabis offers a viable alternative to opioids, potentially improving their quality of life while possessing a superior safety profile,” Armentano writes.
