Investigation of Cannabis for Pain and Inflammation in Lung Cancer

Radiation therapy to the chest is used in late stage lung cancer, and it often leads to inflammation of the esophagus. The inflammation is expected to occur in about 75% of patient, and usually begin within a week of starting radiation therapy. The esophagitis causes pain and difficulty eating. It can also result in stopping or delaying treatment.Radiation therapy to the chest is used in late stage lung cancer, and it often leads to inflammation of the esophagus. The inflammation is expected to occur in about 75% of patient, and usually begin within a week of starting radiation therapy. The esophagitis causes pain and difficulty eating. The endocannabinoid system is prominent in the gastrointestinal system, and cannabis has been shown to greatly inhibit inflammation. The compound (-)-trans-Δ9-tetrahydrocannabinol (Δ-9-THC) has effects that reduce inflammation and pain. Cannabidiol is a component of cannabis that does not produce subjective or intoxicating effects, but also has prominent anti-inflammatory properties. The goal of this study is to perform a double-blind, placebo-controlled study to investigate the efficacy of cannabis, compared to placebo, in participants undergoing RT (Radiation Therapy) for lung cancer. Cannabis that has a high concentration of cannabidiol will be used , which is a cannabinoid that does not change perception or produce intoxication, and low in Δ-9-THC. In this way, the hope is to maximize the benefit of cannabis, while lowering the possible side effects of cannabis in medically ill participants.
