Medicinal use of cannabis in the United States: historical perspectives, current trends, and future directions.
Cannabis (marijuana) has been used for medicinal purposes for millennia, said to be first noted by the Chinese in c. 2737 BCE. Medicinal cannabis arrived in the United States much later, burdened with a remarkably checkered, yet colorful, history. Despite early robust use, after the advent of opioids and aspirin, medicinal cannabis use faded. ⋯ Endocannabinoids appear to control pain, muscle tone, mood state, appetite, and inflammation, among other effects. Cannabis contains more than 100 different cannabinoids and has the capacity for analgesia through neuromodulation in ascending and descending pain pathways, neuroprotection, and anti-inflammatory mechanisms. This article reviews the current and emerging research on the physiological mechanisms of cannabinoids and their applications in managing chronic pain, muscle spasticity, cachexia, and other debilitating problems.

Opioids are the mainstay of management for patients with cancer-related pain. Although the analgesic efficacy of opioid therapy is well documented, the recent European Pain in Cancer survey demonstrated that the management of moderate-to-severe pain in patients with cancer is far from optimal. Bowel dysfunction, and importantly constipation, is a common side effect and has a significant impact on the patient's morbidity and quality of life. ⋯ One promising strategy is the prevention of OIC with peripherally acting opioid antagonists that specifically target the underlying cause of this condition, without affecting centrally mediated analgesia. In recent studies, the novel combination of prolonged-release oral oxycodone and prolonged-release oral naloxone provided effective analgesia with improved bowel function in patients suffering from severe cancer-related and noncancer-related pain. The combination has the potential to improve the quality of pain management significantly in these patients.

Case Reports
Dexmedetomidine as a novel therapeutic for postoperative pain in a patient treated with buprenorphine.
Buprenorphine is a partial agonist/antagonist used for the outpatient management of pain and addiction. It avidly binds to the opioid receptors and has a long and varied half-life. ⋯ The authors present a case of a patient managed with buprenorphine as an outpatient who presented for revision spine surgery and had significant postoperative pain that was successfully treated with hydromorphone and dexmedetomidine. This is the first reported use of dexmedetomidine for postoperative pain in a patient treated with buprenorphine.

To characterize the impact of opioid-induced constipation (OIC) on healthcare resource use, work productivity, and health-related quality of life (HRQOL) in patients receiving chronic opioid therapy. ⋯ The survey results reflect a negative impact of OIC on individuals' HRQOL and on society in terms of healthcare resource use and work productivity beyond that imposed by patients' pain conditions. These findings indicate a need for effective treatment for opioid-induced constipation in patients receiving chronic opioid therapy.
