This study led to the conclusion that high CBD to CBN ratios have a significant effect on reducing muscle withdrawal response (speeds relaxation) without impairing motor function. This essentially means that a high CBD:CBN ratio dose promotes muscular relaxation and inhibits the pain response to stress but does not impair the patient.
These results suggest that peripheral application of these non-psychoactive cannabinoids may provide analgesic (pin) relief for chronic muscle pain disorders such as temporomandibular disorders and fibromyalgia without central side effects.
