The prescription of medical cannabis by a transitional pain service to wean a patient with complex pain from opioid use following liver transplantation: a case report

The purpose of this case report is to describe a patient with a preoperative complex pain syndrome who underwent liver transplantation and was able to reduce his opioid consumption significantly following the initiation of treatment with medical cannabis. Reductions in opioid consumption were achieved with the administration of medical cannabis in a patient with acute postoperative pain superimposed on a chronic pain syndrome and receiving high doses of opioids. Concurrent benefits of initiating medical cannabis may include improvements in pain profile and functional status along with reductions in opioid-related side effects. This highlights the potential for medical cannabis as an adjunct medication for weaning patients from opioid use.

Effect of adding medical cannabis to analgesic treatment in patients with low back pain related to fibromyalgia: an observational cross-over single centre study

Low back pain (LBP) occurs in many patients with fibromyalgia (FM). The current study aimed to assess the possible pain and function amelioration associated with medical cannabis therapy (MCT) in this setting. This observational cross-over study demonstrates an advantage of MCT in FM patients with LBP as compared with standardised analgesic therapy. Further randomised clinical trial studies should assess whether these results can be generalised to the FM population at large.

Cannabis-related cognitive impairment: a prospective evaluation of possible influences on patients with cancer during chemotherapy treatment as a pilot study

In patients with cancer, the use of medical cannabis has increased significantly during the recent years. There is evidence that cannabis consumption may affect cognitive performance; however, this potential effect has not been investigated prospectively in patients with cancer to date. We aimed to evaluate the effect of cannabis consumption on cognitive abilities as well as on symptom relief in patients with cancer during chemotherapy treatment. These preliminary findings suggest that the short-term use of cannabis during chemotherapy treatment improved disease-related symptoms and did not affect cognitive skills in patients with cancer.
