Compared to THC, CBD has very different properties. It weakly binds to both CB1 and CB2 receptors in the brain and body, gently stimulating and blocking them at the same time. This not only mildly activates the receptors, but is also thought to trigger the body to create more CB1 and CB2 receptors, a process known as upregulation. It also results in increased natural levels of anandamide.
Cannabis consumers have long prized potency (a high THC content) as one of the main factors that makes a particular strain more desirable. Though traditional demand for THC has caused an oversaturation of high-potency products, many consumers are starting to prefer less intense products that are lower in THC and higher in the non-intoxicating compound called cannabidiol (CBD).
When pain is localized, topical products can be applied. These can be made using CBD-dominant cannabis as well as THC strains. Topicals affect the cells near application and through several layers of tissue but do not cross the blood-brain barrier and are, therefore, not psychoactive. These may be available as CBD oils, ointments, salves, or other forms, and with varying ratios of CBD and THC (a ratio of 1:1 is often recommended as ideal for skin application). The skin has the highest amount and concentration of CB2 receptors in the body.
Cannabinoids, including cannabidiol (CBD), work by mimicking natural endocannabinoids like anandamide (described above) in the body. Endocannabinoids are part of a complex messaging system in the body called the endocannabinoid system. The endocannabinoid system oversees or regulates parts of the nervous system, endorphins, immune system functions, hormones, mood and emotions, metabolism, and many other chemical messengers in the body.
Oral consumption is recommended as it usually lasts the whole night. Always start with the micro dose to test sensitivity and go up as needed within the dosing range before going to the next, until symptoms subside. The micro to standard dose is usually recommended to treat insomnia and sleep apnea. When relaxing indica strains are used with higher THC levels, a dose of 5–10 mg is usually sufficient. Other people find they need larger doses, such as 15–40 mg. CBD taken as a tincture or edible will aid in a restful six to seven hours of sleep. This type of disorder varies widely from one patient to the next. Often, one needs to perform some experimental research and try strains of different CBD:THC ratios to figure out how CBD oil benefits their sleep and the best protocol.
