Companies have unleashed hundreds of CBD pet health products accompanied by glowing customer testimonials claiming the cannabis derivative produced calmer, quieter and pain-free dogs and cats.
But some of these products are all bark and no bite.
â€śYouâ€™d be astounded by the analysis weâ€™ve seen of products on the shelf with virtually no CBD in them,â€ť said Cornell University veterinary researcher Joseph Wakshlag, who studies therapeutic uses for the compound. â€śOr products with 2 milligrams per milliliter, when an effective concentration would be between 25 and 75 milligrams per milliliter. There are plenty of folks looking to make a dollar rather than produce anything thatâ€™s really beneficial.â€ť
Such products can make it to the shelves because the federal government has yet to establish standards for CBD that will help people know whether it works for their pets and how much to give.
Still, thereâ€™s lots of individual success stories that help fuel a $400 million market that grew more than tenfold since last year and is expected to reach $1.7 billion by 2023, according to the cannabis research firm Brightfield Group.
Amy Carter of St. Francis, Wisconsin, decided to go against her veterinarianâ€™s advice and try CBD oil recommended by a friend to treat Bentley, her epileptic Yorkshire terrier-Chihuahua mix. The little dogâ€™s cluster seizures had become more frequent and frightening despite expensive medications.
â€śItâ€™s amazingâ€ť Carter said. â€śBentley was having multiple seizures a week. To have only six in the past seven months is absolutely incredible.â€ť
But some pet owners have found CBD didnâ€™t work.
Dawn Thiele, an accountant in Oak Creek, Wisconsin, said she bought a $53 bottle of CBD oil from a local shop in hopes of calming her 2-year-old Yorkshire terrier during long car trips.
â€śI didnâ€™t see a change in his behavior,â€ť said Thiele.
Short for cannabidiol, CBD is a non-intoxicating molecule found in hemp and marijuana. Both are cannabis plants, but only marijuana has enough of the compound THC to get users high. The vast majority of CBD products come from hemp, which has less than 0.3% THC.
CBD has garnered a devoted following among people who swear by it for everything from stress reduction to better sleep. Passage of the 2018 Farm Bill, which eased federal legal restrictions on hemp cultivation and transport, unleashed a stampede of companies rushing products to the market in an absence of regulations ensuring safety, quality and effectiveness.
Products for people were swiftly followed by CBD chewies, oils and sprays for pets.
â€śThe growth is more rapid than Iâ€™ve seen for any product in 20 years in this business,â€ť said Bill Bookout, president of the National Animal Supplement Council, an industry group whose member companies agree to testing and data-gathering requirements.
The U.S. Food and Drug Administration is developing regulations for marketing CBD products, for pets or people. This year, it has sent warning letters to 22 companies citing violations such as making claims about therapeutic uses and treatment of disease in humans or animals or marketing CBD as a dietary supplement or food ingredient.
â€śItâ€™s really the Wild West out there,â€ť said S. David Moche, founder of Applied Basic Science, a company formed to support Colorado State Universityâ€™s veterinary CBD research and now selling CBD online. He advises consumers to look for a certificate of analysis from a third-party testing laboratory to ensure theyâ€™re getting what they pay for.
â€śTesting and labeling is going to be a critical part of the future of this industry,â€ť Moche said.
Wakshlag said products must also be tested to ensure theyâ€™re free of toxic contaminants such as heavy metals and pesticides and have only trace amounts of THC, which in higher levels is toxic to dogs.
