Baltimore, MD: The use of cannabis is associated with marked improvements in a patient with chronic, treatment-resistant pruritus, according to data published in JAMA Dermatology.
A team of investigators with John Hopkins University in Baltimore reported on the use of cannabis by a woman in her 60s with a 10-year history of pruritus. The subject was unresponsive to multiple anti-pruritic therapies, including topical corticosteroids.
Following the use of either botanical cannabis and/or cannabis tinctures, the patient’s symptoms improved significantly. The patient experienced sustained improvements associated with cannabis over a 20-month period, with her Dermatology Life Quality Index Score falling from 17 to 1 over that period of time. The subject also reported ceasing her intake of other anti-prurtic medications. Minimal adverse effects were reported.
Researchers reported: “This case report highlights that medical marijuana is a potential treatment for chronic pruritus, which is especially relevant as a growing number of states pass legislation allowing public medical marijuana programs. These findings are promising, but randomized clinical trials are needed to confirm the results.”
