Cannabis has been used to treat pain since as far back as 2900 B.C. (2Trusted Source). More recently, scientists have discovered that certain components of cannabis, including CBD, are responsible for its pain-relieving effects. The human body contains a specialized system called the endocannabinoid system, which is involved in regulating a variety of functions, including sleep, appetite, pain sensation, and immune system response (3Trusted Source). The body produces endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors in your nervous system. Anxiety disorders and other mental health disorders can have devastating impacts on overall health and well-being. Mental health disorders are often treated with pharmaceutical drugs, which can cause a number of side effects, including drowsiness, agitation, insomnia, sexual dysfunction, and headaches (11Trusted Source). What’s more, medications like benzodiazepines have the potential for dependence and may lead to substance use disorder.
