The FDA actually issued a warning for making false claims of effectiveness and medicinal benefits because so many illegitimate companies sell snake oil marketed as CBD that doesn't do anything (here's how to avoid that). Despite all these challenges, if you know what you're buying, hemp-derived CBD oil as a product itself is not illegal, according to federal law.
While overstimulation of the CB1 receptor may lead to symptoms such as high blood pressure and abnormally high cholesterol levels, CBD is a CB1 antagonist, so it is not likely to cause such issues. Furthermore, the World Health Organization has recently issued a global report on CBD, claiming that it has a good safety profile and minimal adverse public health effects.
Real Scientific Hemp Oil touts itself as being somewhat of a pioneer, as – according to the company – its own variety of CBD oil was the first to hit the mainstream back in 2012. In addition, the brand claims that its RSHO-X CBD liquid is the earliest no-THC product of its kind, making it a sound choice for those worried about whether CBD oil use will influence the results of drug tests. The company is also transparent about the processes that go into making its varieties of CBD-containing hemp oils, helping customers make informed choices as to which of its products are best for them. And minds may be put at ease upon learning that Real Scientific Hemp Oil tests its CBD oil three times – a process which seems to speak to the quality, purity and safety of the provider’s wares.
More human studies are needed to fully understand the range of risks and side effects that CBD oil may cause. Studies of CBD oil aren’t common. This is partially because Schedule 1 substances like cannabis are highly regulated, causing some obstacles for researchers. With the legalization of marijuana products, more research is possible, and more answers will come.
