A new study in the Australian and New Zealand Journal of Obstetrics and Gynaecology reports that cannabis-based medicines may offer sustained relief for people living with endometriosis-related chronic pain. Researchers followed 63 patients over 18 months and recorded statistically significant improvements in multiple pain measures at every follow-up point.​

Participants also reported better overall quality of life, improved sleep and reduced anxiety, with clinical gains on standard pain and symptom scales ranging up to 37% depending on the measure. While 16 patients experienced a total of 62 adverse events, investigators found no unexpected safety issues.​

Because the research was observational, the authors cautioned that it cannot prove cannabis caused the improvements, and called for controlled clinical trials to confirm the findings. The full report is covered by The Marijuana Herald.
