CBD oil is generally considered to be safe for most people, and few people experience side effects. Most that do use higher doses of CBD oil than are generally available for over-the-counter use.
It depends on where you live. Because it has been derived from THC-rich marijuana, marijuana-derived CBD. even itsisolated from is considered a byproduct of marijuana and is judged accordingly. In some states, marijuana-derived CBD s completely legal, while in others, it is completely illegal, but in most states, it's a bit of a mixed bag, with each state having CBD-specific laws.
Cannabinoids are naturally found in the hemp plant. The most abundant one found in the hemp plant may promote and support the nutritional health of aging bodies. Source: U.S. government patent on Cannabinoids as Antioxidants and Neuroprotectant #6,630,507. Cannabinoids interact with our endocannabinoid system, which consists of a series of receptors located in the brain, central nervous system, and many other areas. The ECS helps promote/regulate various important biological processes, Our bodies produce some cannabinoids (like anandamide) on their own.
That said individuals using unusually large doses of a cannabinoid-rich hemp oil product (above 1000-2000 mg of hemp oil daily) could theoretically test positive during an initial urinary screen. Although VERY RARE, the urine cases would likely represent a "false positive" due to the other non-THC metabolites or compounds. When this is the case, the confirmatory GC/MC test would be negative, since CBD and other cannabinoids will not be detected by the more accurate (and specific) GC/MS screen.
Keep in my mind that most of the high quality, reliable CBD-rich hemp oil products contain much less THC than marijuana. For example, hemp contains anywhere from 1/10th to 1/300th of the THC concentration found in marijuana. An individual consuming 1000-2000 mg per day of hemp oil would thus consume approximately 3-6mg of THC. This exceedingly high dose may result in detection of a positive urine screen in up to 11% to 23% of assays.
On the other hand, there is some data demonstrating that at daily doses of 0.5mg of THC from 3-5 servings of most commercial CBD-rich hemp oil products, the positive urine screen rate is less than 0.2%. Again most servings of typical high-quality, high purity CBD based hemp oil products contain well below of 0.1mg THC and therefore have over 400-600 times less THC than marijuana products.
What does all this mean? Put simply, a customer who uses a high-quality scientifically vetted hemp-based product at standard serving size is highly unlikely to test positive for THC and/or THC/-COOH. However, it's important to cognizant that extremely high doses may result in a positive urine screen (that would subsequently be false via GC/MS. Ultimately customers need to be fully informed of the specific regulations posed by the their employers and adjust their consumption of cannobinoid products accordingly.
