Depending on the kind of joint pain you have, you can explore different ways of medicating cannabis. For example, studies show that CBD is ideal for treating inflammatory pain, which is common among those suffering from injuries or arthritis. Scientists believe that CBD works in many ways to reduce inflammation, one of these ways is by blocking the inflammatory markers.  Other studies show that CBD increases the work of glycine receptors which are responsible for regulating pain and as a result, reduce neuropathic pain.
