Analysis: THC Dosing Associated With Increased Survival Time In Palliative Cancer Patients

Berlin, Germany: The daily use of 5mg of oral THC is associated with increased survival times in palliative cancer patients, according to data published in the journal Medical Cannabis and Cannabinoids.

German researchers evaluated the impact of THC dosing in a cohort of 9,419 advanced cancer patients enrolled in Specialized Palliative Outpatient Care (SAPC). SAPC offers team-based home care for patients with advanced and progressive diseases whose life expectancies are limited to days, weeks, or months. 

Researchers reported that patients’ daily use of 4.7mg of THC was associated with significantly increased survival time, whereas lower doses were not. 

The study’s authors concluded: “The data … show a significant impact of THC on survival in ambulatory palliative care patients [who] … use more than 4.7 mg/day. Median survival time was prolonged by 15 days – from survival time of 25 days without THC therapy to 40 days with a daily THC dose higher than 4.7 mg per day. This prolongation by more than two weeks can be considered substantial. In addition to mere survival, patients [treated] with THC become more mentally and physically active. … The increased activity and improved quality of life might enable the patients to renew social contact with relatives and friends and to settle essential affairs before dying.”

The study’s findings are consistent with data published in 2021 that similarly reported that THC was associated with increased survival times in German hospice patients, particularly among women ages 75 and older.
