In the US you cannot be fired for the use of legal products. Check your local laws but I’m pretty sure CBD-only products are legal in all 50 states because they contain no THC or a negligent amount of it. That being said, if you are taking very high doses of CBD it is possible for a very small amount of THC to be detected, but this would be considered a false-positive result.
Hemp Oil contains naturally occurring phyto-cannabinoids, including CBD. It is widely consumed for its numerous wellness properties: as mild analgesic, antiinflamatory, antioxidant and antiemetic to name a few. Sträva uses the finest, full-spectrum hemp oil sourced from respected growers in Europe and Colorado. This oil is naturally rich in phyto-cannabinoids, including CBD, as well as constituents such as amino acids, vitamins B1, B2 and D, omega-3 and omega-6 fatty acids, minerals zinc, calcium and magnesium. Hemp Oil and CBD are non-psychoactive and do not produce a "high."
In the United States, federal and state laws regarding the medical use of cannabis and cannabinoids are in conflict and have led to confusion among patients, caregivers, and healthcare providers. Currently, cannabis is legal for medical purposes in 50% of the states, and another seventeen states allow products that are high in cannabidiol (CBD) and low in THC (tetrahydrocannabinol) for medical use. Many of these artisanal products are sold in dispensaries or over the internet. However, none of these products has been approved by the Food and Drug Administration (FDA). Understanding how federal laws apply to clinical research and practice can be challenging, and the complexity of these laws has resulted in particular confusion regarding the legal status of CBD. This paper provides an up-to-date overview (as of August 2016) of the legal aspects of cannabis and cannabidiol, including cultivation, manufacture, distribution, and use for medical purposes.
