Chronic pain patients who used cannabis saw sustained improvement in their condition over time, according to the results of a recently released study. An abstract of the research, “No pain, all gain? Interim analyses from a longitudinal, observational study examining the impact of medical cannabis treatment on chronic pain and related symptoms,” was posted online last month prior to publication by the journal Experimental and Clinical Psychopharmacology.
To complete the study, researchers working with the Harvard Medical School and McLean Hospital in Boston evaluated the use of medical cannabis (MC) by chronic pain patients, most of whom had either musculoskeletal pain or neuropathy. Patients were evaluated for factors including pain, clinical state, sleep, quality of life, and conventional medication use before the onset of treatment, as well as after three and six months of using medical cannabis. The data revealed a sustained improvement in the participants’ symptoms.
“Relative to baseline, following 3 and 6 months of treatment, MC patients exhibited improvements in pain which were accompanied by improved sleep, mood, anxiety, and quality of life, and stable conventional medication use,” the researchers wrote. “Reduced pain was associated with improvements in aspects of mood and anxiety.”
Different Effects Noted For THC, CBD
The research also revealed potential differences in the effects of increased exposure to the cannabinoids THC and CBD on different symptoms experienced by the participants, writing that “findings highlight the potential efficacy of MC treatment for pain and underscore the unique impact of individual cannabinoids on specific aspects of pain and comorbid symptoms.”
