You can think of the full spectrum of all the chemical compounds found in cannabis as the “language” of the plant. It’s not one chemical, but all the chemicals combined working together that cause a response (again, the entourage effect). When you consume CBD oil, you gain the benefits of all those chemical substances in natural synergy. For that reason, you get full benefit at a dose range of 25-50 mg.
Still, CBD presents other risks for false positives. "If people are using CBD products that don't have a CoA (Certificate of Analysis) that indicates zero THC, THC could show up on a drug screen," Okel says. Availability of CBD oil has exploded, but it's not a well-regulated industry. Some oils that claim to be pure CBD have some sneaky THC in there, and that could mess up a drug test. Okel advises everyone to only purchase CBD oils with CoA purity guarantee to avoid ingesting trace amounts of THC.
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.
