Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
As mentioned above, cannabis and hemp differ in the levels of naturally occurring THC that they contain. THC is a cannabinoid like CBD. However, its properties are very different and often antagonistic to the effects of CBD. Hemp is naturally high in CBD and low in THC; the reverse is true of cannabis. In fact, hemp contains only about 0.3% – 1.5% THC, while cannabis contains about 5% – 10% or more THC.
The exact legality of CBD is tricky. The Drug Enforcement Administration maintains that CBD is federally illegal but will not bother going after anyone for possessing or using it. Many argue that a provision in the 2014 farm bill allowing industrial hemp pilot programs, mostly aimed at the textile industry, actually made non-THC use of cannabis legal; while the much-delayed 2018 farm bill signed into law at the end of the year made industrial hemp legal nationwide, CBD has largely yet to be reclassified.
I wanted to tell people here that CBD has been very effective for my anxiety, and helps with insomnia. For me, it was a cumulative effect, after a week of one dropper of oil, I can sleep very well at night. I feel like I am not polluting my body with commercial pharmaceuticals. I wish everyone here the best, and hope it works for you as well as it has for me.

A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders. Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions. This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content. Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.
