Several studies have shown that marijuana can reduce the intensity of pain. However, researchers also stated the need for more evidence in the area to confirm these findings.
A study titled "Smoked cannabis for chronic neuropathic pain: a randomized controlled trial" revealed that inhaling 25mg of herbal cannabis three times daily for five days can reduce the intensity of pain and improve sleep.
A similar study was conducted on "Effect of cannabis use in people with chronic non-cancer pain prescribed opioids: findings from a 4-year prospective cohort study." This study showed that cannabis use was common among people with chronic non-cancer pain, but said that there was no evidence that cannabis use improved patient outcomes. Also, the people in the study who used cannabis experienced greater pain.
A clinical review on the use of medical marijuana found that there was high-quality evidence that marijuana helped chronic and neuropathic pain. Six trials from the study included 325 patients examined for chronic pain; another six trials included 396 patients investigated for neuropathic pain. Several of these trials showed positive results, suggested that marijuana may be beneficial in controlling pain.
A blog from a Harvard Medical school also pointed out that marijuana can be used to relieve pain in the patients and said that more studies on humans are required for substantiating the claims on marijuana advocating about pain control.
