Previous studies have investigated the use of cannabis-based therapy in areas such as chronic pain, nausea, and anorexia. A review of current literature has now determined that the anti-inflammatory properties of cannabinoids could make them useful in the treatment of a wide-range of skin diseases.

Writing in the Journal of the American Academy of Dermatology , the authors said cannabinoids have a promising role in the treatment of itch. Studies to date have shown benefits with the use of cannabinoids in conditions such as pruritis, xerosis, prurigo and allergic dermatitis, to name but a few. 

While the findings are promising, Dellavalle cautioned that most of these studies are based on laboratory models and large-scale clinical trials have not been performed before these therapies can be used for the management of dermatological conditions in practice. He said however, that for those who have used other medications for skin disease without success, trying a cannabinoid is a viable option. 

"These diseases cause a lot of problems for people and have a direct impact on their quality of life," he said. "The treatments are currently being bought over the internet and we need to educate dermatologists and patients about the potential uses of them."
