And Welty said that studies that have counted on humans for those other uses of the Sera Labs CBD Oil have been case reports or studies that did not compare the results with a control group that did not use the oil. There is no control, so basically, how do you know that it is a true effect of the substance or just a placebo effect because someone believes you have received a beneficial substance? Said Welty.
Due to the confusing legal nature of marijuana, the FDA has not intervened to regulate products such as CBD oil, Bonn-Miller said. The states are struggling to create regulations, but they do not have as many economic resources as the federal government.
On the other hand, a 2017 study conducted by Bonn-Miller found that almost 7 out of 10 CBD products did not contain the amount of marijuana extract promised on the label. There are also concerns about both the quality of the Sera Labs CBD Oil oil that is being produced and its potential side effects, the experts added.
