Cannabis Research: Chronic Pain Posted on 15 Jan 13:43

Chronic pain is pain that persists for more than 6 months. They are often a symptom of an underlying disease, such as cancer and multiple sclerosis, but can also be caused by a simple injury or infection. Chronic pain can take many forms, be it mild or excruciating and has in those affected usually a slow emotional impact. Prescribed drugs can often be ineffective or have undesirable side effects, so the effect of cannabis has been explored as a pain reliever.
Studies in this area:
1) Smoked medicinal cannabis for neuropathic pain in HIV: a randomized, clinical cross-over study (Smoked Medicinal Cannabis for Neuropathic Pain in HIV: A Randomized, Crossover Clinical Trial - 2008)
This study was conducted to determine how effectively acts cannabis in the treatment of chronic pain caused by nerve, caused by HIV. Here it was found that participants reported with the use of cannabis from a better pain relief than those who were given a placebo and that it was most effective when it was used in conjunction with other pain relieving therapies. Published in the journal "Neuropsychopharmacology."
2) Dose-dependent effects of smoked cannabis on capsaicin-induced pain and hyperalgesia by in healthy volunteers (Dose-dependent Effects of Smoked Cannabis on Capsaicin-induced Pain and Hyperalgesia in Healthy Volunteers - 2007)
Researchers conducted this study to examine how smoking cannabis would affect the perception of pain in patients induced with capsaicin pain suffered (the compound in chili peppers that causes a burning sensation when it comes in contact with tissue). They found that those who smoked a mean dose reported a significant reduction in pain, while those who smoked a higher dose, reported a significant increase in the induced pain. Published in the journal "Anesthesiology."
3) cannabinoids for the treatment of chronic pain that is not caused by tumors, a systematic review of randomized trials. (Cannabinoids for treatment of chronic non-cancer pain, a systematic review of randomized trials - 2011)
This study aimed to demonstrate the limited options that are available for those who suffer from chronic pain. They introduced random studies that compared the cannabis with a placebo and their effect on pain. It has been found that the use, cannabis, compared to those with a placebo, reported a significant pain reduction. Moreover, it has been found that the use of triggered no serious side effects. In summary, it was found that cannabinoids appear to be an effective and safe way to treat pain. Published in the "U.S. National Library of Medicine."
