Hutchison is particularly wary of problems with CBD’s retail dosage and Labeling. Given that CBD products are not only in golf shops but supermarkets, drugstores and gas stations, the buyer-beware aspect of this phenomenon can be overwhelming. Though CBD doesn’t appear to have any significant side effects at this point, it’s not entirely clear that what you’re getting is what’s on the label. And because CBD isn’t regulated by the FDA, there are no standards or guarantees. Depending on what you purchase, the possibility exists that there could be enough THC in it to have you fail an employer’s drug test. Conversely, any product could tout any amount of CBD it wants on its label, and it might not have any CBD in it at all. At the FDA’s public hearing in May, Dr. Rosemary Mazanet, chief scientific officer for the medical marijuana company Columbia Care, testified that as much as 69 percent of CBD products in one study were mislabeled.
