Cannabis inhalation is associated with sustained improvements in pain and sleep in patients with chronic neuropathy, according to data published in the journal Medical Cannabis and Cannabinoids.
German investigators assessed the use of herbal cannabis in a cohort of 99 patients suffering from neuropathic pain. Participants in the study inhaled cannabis containing moderate levels of THC (12 to 22 percent) for six weeks.
Researchers reported: “Within six weeks on the therapy, median pain scores decreased significantly from 7.5 to 4.0. The proportion of patients with severe pain (score >6) decreased from 96 percent to 16 percent. Sleep disturbance was significantly improved with the median of the scores decreased from 8.0 to 2.0. These improvements were sustained over a period of up to six months. There were no severe adverse events reported.”
Other surveys have identified similar pain decreases in neuropathy patients following their initiation of cannabis therapy.
The study’s authors concluded, “The results … demonstrated that chronic neuropathic pain can be effectively, sustainably, and safely treated with medical cannabis.”
Data published earlier this year in the Journal of the American Medical Association (JAMA) Network Open reported that nearly one in three patients with chronic pain use cannabis as an analgesic agent and that many of them substitute it in place of opioids.
