The U.S. Food and Drug Administration issued a warning letter to Curaleaf Inc., of Wakefield, Massachusetts, for illegally selling unapproved products containing CBD with unsubstantiated claims that their products treat cancer, Alzheimer’s disease, opioid withdraw, pain and pet anxiety, among other conditions and diseases.

“As we examine potential regulatory pathways for the lawful marketing of products containing cannabis and cannabis-derived compounds like CBD, protecting and promoting public health remains our top priority. Selling unapproved products with unsubstantiated therapeutic claims — such as claims that CBD products can treat serious diseases and conditions — can put patients and consumers at risk by leading them to put off important medical care. Additionally, there are many unanswered questions about the science, safety, effectiveness and quality of unapproved products containing CBD,” said Acting FDA Commissioner Ned Sharpless, M.D. “Today’s action demonstrates that the agency stands firm in its commitment to continue monitoring the marketplace and protecting the public health by taking action as needed against companies that deceive consumers and put them at risk by illegally selling products marketed for therapeutic uses for which they are not approved, such as those claiming to treat cancer or Alzheimer’s disease. Consumers should beware of purchasing or using any such products.”


Examples of the unsupported and unapproved claims made by the company include:

  • “CBD has been demonstrated to have properties that counteract the growth of [and/or] spread of cancer.”
  • “CBD was effective in killing human breast cancer cells.” • “CBD has also been shown to be effective in treating Parkinson’s disease.”
  • “CBD has been linked to the effective treatment of Alzheimer’s disease ….”
  •  “CBD is being adopted more and more as a natural alternative to pharmaceutical-grade treatments for depression and anxiety.”
  • “CBD can also be used in conjunction with opioid medications, and a number of studies have demonstrated that CBD can in fact reduce the severity of opioid-related withdrawal and lessen the buildup of tolerance.”
  • “CBD oil is becoming a popular, all-natural source of relief used to address the symptoms of many common conditions, such as chronic pain, anxiety … ADHD.”
  • “What are the benefits of CBD oil? …. Some of the most researched and well-supported hemp oil uses include …. Anxiety, depression, post-traumatic stress disorders, and even schizophrenia …. Chronic pain from fibromyalgia, slipped spinal discs . . . Eating disorders and addiction . . ..”
  • “[V]ets will prescribe puppy Xanax to pet owners which can help in certain instances but is not necessarily a desirable medication to give your dog continually. Whereas CBD oil is natural and offers similar results without the use of chemicals.”
  • “For dogs experiencing pain, spasms, anxiety, nausea or inflammation often associated with cancer treatments, CBD (aka cannabidiol) may be a source of much-needed relief.”

FDA has concluded based on available evidence that CBD products are excluded from the dietary supplement definition under sections 201(ff)(3)(B)(i) and (ii) of the FD&C Act, 21 U.S.C. 321(ff)(3)(B)(i) and (ii). Under those provisions, if an article (such as CBD) is an active ingredient in a drug product that has been approved under section 505 of the FD&C Act, 21 U.S.C. 355, or has been authorized for investigation as a new drug for which substantial clinical investigations have been instituted and for which the existence of such investigations has been made public, then products containing that substance are outside the definition of a dietary supplement.

Currently, consumers can Buy CBD Oil just about anywhere. With the lack of regulation and oversight, it’s becoming more difficult for consumers to decipher quality CBD Oil vs Snake Oil.

Going with a reputable 3rd party tested company like NuLeaf Naturals is a good way to go until more insight and regulation becomes available.
