FDA Sends Warning Letters to Curaleaf

Curaleaf Hemp, a well-known and publicly traded cannabis company, made headlines this week for all the wrong reasons. The US Food & Drug Administration (FDA) sent a warning letter to Curaleaf President Joseph Lusardi for making unsubstantiated health claims and for misbranding their products as drugs.

FDAThe health claims in question appear to be removed from their website and social media accounts. In the warning letter, the FDA cites numerous claims made on Curaleaf’s website, Twitter and Facebook accounts. You can check out the health claims they found here, but it’s essentially a list of instances where Curaleaf said their products can be used to treat specific conditions. They claimed their CBD vape pen can be used for chronic pain and said another one of their products is a “[S]oothing tincture for chronic pain.”

For most of the health claims the FDA cited, it appeared they were articles or blog posts on Curaleaf’s website. Take a look at some examples of statements that should not be posted on a CBD products website (taken from the warning letter found here):

  • “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 has been demonstrated to have properties that counteract the growth of spread of cancer.”
  • “CBD was effective in killing human breast cancer cells.”
  • “Heart disease is one of the leading causes of death in the United States each year, and CBD does a number of things to deter it. The two most important of these are the ability to lower blood pressure, and the ability to promote good cholesterol and lower bad cholesterol.”

While the FDA is expediting their push to roll out hemp and CBD regulations, companies should still be cautious when marketing their products for interstate commerce. Dr. Amy Abernathy, Principal Deputy Commissioner and Acting CIO, said in a series of tweets earlier this month that the FDA is eager to get to work and plans to report on their progress by the end of summer. The public hearing they held back in May helped jumpstart their efforts to begin investigating regulation of the market.

Still, companies need to be careful when marketing CBD products. The FDA has made it abundantly clear in a lot of warning letters that drug claims are not allowed. Here are two articles that give advice on how companies should proceed with marketing and how to go about properly labeling their products.

How to Vet Suppliers in Cannabis Product Manufacturing

The quality of your edible cannabis product can only be as reliable as the components that comprise it. The three types of components include active ingredients (such as CBD oil), packaging components  (such as the bottles that hold finished product) and inactive ingredients (such as coconut oil). When evaluating a potential supplier for these three areas, a risk-based method follows a vendor selection process that highlights critical ingredients and also adequately assesses excipients. With this approach, the vetting process for a supplier is based on the impact the potential ingredient or component will have on the quality and purity of the finished product.

Choose only those suppliers who can provide certification that the packaging components are food-grade or food-safeThere are three basic categories to guide vendor assessment. Is the supplier providing 1) a packaging component with product contact, 2) an excipient, or inactive ingredient, or 3) the active ingredient? Regardless of the category, due to the factious nature of cannabis, it is important to first verify with a vendor that it will sell its products to a company in the cannabis industry. Once that is determined, the evaluation process may begin.

Packaging Components

Packaging components, such as bottles and caps, are considered primary packaging because they have direct contact with the finished product. Suppliers of the primary packaging must be able to provide assurance that their goods do not contain additives that are harmful to consumers. Therefore, choose only those suppliers who can provide certification that the packaging components are food-grade or food-safe. Reputable vendors will also be able to provide a certificate of compliance, also known as a certificate of conformance, which states that the component meets specifications required for that part. Many cannabis regulations require finished products to be sold in child-resistant packaging, so the supplier will need to provide child-resistant certification for the packaging components, if applicable.

Excipients

Excipients are ingredients that are added to a product for the purposes of streamlining the manufacturing process and enhancing physical characteristics such as taste and color. Some examples could include coconut oil, starch and alcohol. Though they do not have the same critical nature as active ingredients, their potential risk to a finished product is generally greater than that of a packaging component. As such, there are additional factors to consider for an excipient vendor. Verify with the supplier that it can provide the following documentation. While governing regulations may not require some information, the data included in these documents are important to ensure the quality of your finished product.

  • Certificate of Analysis (or, certificate of conformance), for each lot of material. The information on a certificate, including the tests performed, specifications and test results must be sufficient to determine if the material is acceptable for use in the product.
  • Allergen Statement. This statement is important to accurately include or disclaim allergens on the finished product label.
  • Residual Solvent Statement. Solvents are commonly used to bolster the manufacturing process for a material. In order to maintain acceptable levels of residual solvents in a final product, it is necessary to also consider the toxicity and level of each solvent in the raw material.
  • Heavy Metals Certification. Since metals pose a risk to consumer safety, it is important to know what amounts, if any, are being contributed to your product by raw materials.

Because changes in an excipient can impact your finished product, make every attempt to obtain a commitment from a supplier to notify you if changes are made to the excipient’s specifications.

Active Ingredients

Cannabis oil is the ingredient that, when the edible cannabis product is consumed, is biologically “active.” Thus, it is considered to be the active ingredient in cannabis products. Since cannabis oil has a direct impact on the quality of a product, it is critical that the oil supplier be appropriately evaluated. One of the main considerations for a cannabis oil supplier is whether the supplier is willing to host initial and periodic audits of its manufacturing facility. Such audits are crucial in assessing the capability of the vendor to comply with regulatory requirements and established procedures – can the supplier consistently provide quality material? The answer to this question is too important to risk for you and your customers.As anyone working in the industry has experienced, anything related to cannabis is placed under an unprecedented critical lens.

Additionally, verify the oil supplier will provide key documentation, such as that listed above for excipients, to support the quality and purity of the oil. And last but not least, ensure the information reported by the supplier is adequate to meet the requirements of your finished product.

Evaluation guidelines and criteria such as these should be added to standard operating procedures to ensure consistency and quality across all products. As anyone working in the industry has experienced, anything related to cannabis is placed under an unprecedented critical lens. The importance of consumer safety and bolstering industry integrity is paramount. Sourcing validation is a critical initial step in the production process that can directly impact a company’s success and longevity in the cannabis industry.
