For the third time, the FDA reminded us that it still hasn’t evaluated CBD products for pets. Cannabis products are all the rage, and we’re seeing CBD products everywhere—including pet shops. So what’s the deal with CBD? Are there any safety concerns? Find out more! The FDA has lagged far behind in regulating CBD and other cannabis-derived products, resulting in a miasma of confusion for veterinarians, who in most states, are prohibited from recommending the drug; for companies that market products for pets; and for pet owners, who must take their chances…
FDA Warns Against Unregulated CBD Products for Dog Anxiety Amid Fireworks
The US Food and Drug Administration’s (FDA) Center for Veterinary Medicine sounded the alarm on Thursday—pleading with pet owners to avoid using unregulated cannabidiol (CBD) products for dogs dealing with anxiety due to scary fireworks noises.
Fireworks have long been recognized as an anxiety trigger for dogs, especially those that already have an anxiety-related condition. Dogs are typically known for their olfactory prowess, however according to Smithsonian Magazine, dogs hear more than twice as many frequencies in sound as humans—providing an explanation for their behavior on the Fourth of July. They can also hear sounds four times farther away than humans. To a dog, a crashing boom could sound like an explosion or some other type of calamity.
“Fourth of July can be a noisy and stressful time for dogs, The FDA’s Center for Veterinary Medicine tweeted Thursday. “Ask your vet about the right way to help relieve your dog’s stress through behavior modification or an FDA-approved drug for sedation or to treat noise aversion.”
But the FDA felt the need to call out one popular anxiety remedy by name—CBD—which is commonly used to treat anxiety in dogs and cats, often marketed as pet treats.
“There’s a lot of talk about CBD for treating [dogs] who react to loud noises. You should be aware that FDA has NOT evaluated these products and can’t say whether they are safe or effective, how they are manufactured, or whether they contain CBD.”
Keep in mind that this is the third time the FDA has issued a similar warning ahead of July 4 celebrations—meaning that the organization just admitted that it still hasn’t done its job to evaluate CBD products for their safety, even after three years of warnings.
One real reason to listen to the FDA is that many pet products that claim to be infused with CBD contain no CBD at all, according to the Associated Press. Online grifters will sell bottles of “CBD oil” for well over $50 to people who fall prey to their schemes.
While research is young, early data suggests that CBD could be effective for certain pet-related conditions, perhaps more in dogs than in cats. “CBD-rich hemp nutraceuticals appear to be safe in healthy adult dogs,” researchers wrote in an examination of CBD’s safety profile for use against anxiety, seizures, cancer and pain.
In July 2018, the first clinical study to measure the efficacy of hemp-derived CBD on dogs was published in Frontiers in Veterinary Science, in this case, for dogs living with arthritis. Several more studies have explored different potential benefits.
The FDA is Standing in the Way of Progress
CBD-infused pet treats are widely available, especially after the 2018 Farm Bill was put into place. But that’s not to say that the FDA tolerates them to the fullest degree. For instance, the FDA is notoriously strict about medical claims—both for humans and pets. Benefits from CBD pet treats are not yet proven in dogs nor cats.
Less than a month after the United States Department of Agriculture (USDA) published draft final rules to allow for the production and interstate shipment of hemp-derived CBD products throughout the country, the FDA issued warning letters to no fewer than 13 companies in nine states for selling pet treats or foods infused with CBD. “The FDA is also indicating today that it cannot conclude that CBD is generally recognized as safe (GRAS) among qualified experts for its use in human or animal food,” the organization wrote.
For the time being, hemp-derived CBD treats marketed to both dogs and cats can be found freely across the internet, in convenience stores and in dispensaries in multiple states.
Pet owners are encouraged to designate a safe haven to help keep your dogs calm during the onslaught of fireworks this holiday. Dogs can also be slowly desensitized to firework noises, once they get used to hearing them repeatedly.
CBD Oil For Dogs Fda Approved
Anywhere you look nowadays, you’re bound to spot something about marijuana and its components CBD (cannabidiol) and THC (tetrahydrocannabinol). With medical marijuana now legal in over half the states, and an increasing number of states legalizing recreational marijuana, there’s been a rise in CBD products (like oils and treats) in mainstream shops and retail chains. And recently, the trend has carried over to our four-legged-friends.
This is leading pet owners to ask: If marijuana or CBD is helpful for some people, can it help my pet? The ASPCA Animal Poison Control Center (APCC) weighs in on this trending topic.
A Little Background
One of the first things to understand is a breakdown of the properties associated with marijuana and CBD. Marijuana, also known as Cannabis Sativa, is a plant. In the cannabis plant, both THC and CBD can be found to varying degrees. The plant contains many compounds, but the one it is most recognized for is THC. THC is considered a psychoactive substance, which means that it is a chemical that changes how the brain functions, and thus can cause alterations in perception, mood, consciousness or behavior. Lately, however, CBD has been getting more and more attention for its potential therapeutic and pain management effects.
What We Know
Unfortunately, there are many unanswered questions about the effects of marijuana and CBD in pets. But research into these effects is underway. Studies are slowly being done to look at the potential benefits of CBD for controlling pain from conditions such as osteoarthritis, calming anxious pets and if it may help with treating epilepsy in dogs.
Like with any product, you should consult with your veterinarian to determine if CBD products are right for your pet, and what the proper dosage should be. There’s a lot of information online that can be misleading, and consulting with a professional should always be your first step. That’s especially important if your pet is on other medications. Mixing medications and substances can affect animals’ livers. Just like with any medication or pet product, you want to be careful of overdosing your pet and be sure to keep any CBD products safely up and out of paws’ reach.
The laws around use of cannabis in people and pets have been slow in keeping up with public opinion. The DEA still considers marijuana a Schedule I drug, meaning it is not considered to have any medical use.
Even in states where medical marijuana is legal for people, it is not legal for pets. CBD is regulated by the FDA and currently there are no FDA approved CBD products for pets. In 2018, hemp, a cannabis plant that naturally has less than 0.3% THC, was taken off the federal controlled substances list.
Many companies are marketing products to pets as hemp-based products to skirt the current legal status of marijuana and CBD for pets. However, since these products are not FDA approved, they do not undergo the same quality control measures as medications do, which could potentially prove to be problematic.
With public opinion largely being positive for marijuana and CBD, states are starting to look more closely at the laws and starting to reconsider them. Furthermore, with the added attention, more studies are looking at the potential effects and benefits CBD and marijuana may hold for pets. Many veterinarians are recommending CBD oils and treats for animals with certain conditions, and the popularity of this growing trend doesn’t seem to be slowing down any time soon.
APCC will stay on top of new studies and research as they develop, and keep you informed to help keep your pets happy and healthy.
If you suspect your pet has been exposed to any poisonous substances or ingested something dangerous, contact your veterinarian or call Animal Poison Control Center (APCC) at 888-426-4435 immediately.
FDA continues to ‘caution ‘ pet owners about CBD products as companies and veterinarians clamor for clear guidelines
Until a few weeks ago, dog owners searching for a way to calm their anxious canines could purchase “Nobel Hemp Pet Comfort Tincture” on the website of M Six Labs, one of many companies marketing cannabis-derived products for pets. The company claimed on its website that the tincture, which contained cannabidiol or CBD, could aid pets’ seizure disorders, ease pain and inflammation and “reduce anxiety and nervousness.”
CBD: “unnapproved new animal drugs”
In early May, however, M Six Labs received a sharply-worded letter from the U.S. Food and Drug Administration, which has jurisdiction over cannabis and cannabis-derived products. Sale of the CBD tincture and several other products intended for pets sold by the company, the FDA letter said, violated the federal Food, Drug and Cosmetic Act because CBD was an “unapproved new animal drugs” whose safety and effectiveness had not been scientifically demonstrated. If the violations were not addressed, wrote the agency, “this matter may result in legal action.” Similar letters were sent to other companies that market cannabis-derived products.
Despite his website’s promises about aiding seizure disorders, easing pain and reducing anxiety, Mark Hubbard, chief science officer of M Six Labs, said in an interview with The Canine Review, “We’re not making any medical claims and any intention to use [our products] for any medical benefit are not our intention.”
“This entire industry is very gray—there are no parameters that are black and white.”
However, in response to the FDA’s warning, Hubbard said, M Six Labs removed the claims about the effectiveness of the tincture and other pet products from its website. Pet products, he said, represented a small fraction of the company’s business, which mostly sells products intended for humans. “We’re changing all the labeling that was in question, all the statements that were within the website, removing blogs, scrubbing social media pages,” Hubbard said. But he added, “This entire industry is very gray—there are no parameters that are black and white.”
By 2028, an almost $5 billion dollar industry
Over the last four years, sales of CBD pet products have mushroomed into a major industry; the global market for the products is expected to reach $729 million this year and swell to more than 4.79 billion by 2028, according to an analysis last year by Research and Markets, a marketing research and consultancy firm. Most states now have statutes legalizing marijuana for medical and/or recreational use. And at the federal level, although marijuana remains illegal, the 2018 Farm Bill allowed the commercial production of hemp, a cannabis plant that contains CBD but has lower concentrations of tetrahydrocannabinol or THC. THC is the compound that produces a “high.” But the FDA has lagged far behind in regulating CBD and other cannabis-derived products, resulting in a miasma of confusion for veterinarians, who in most states, are prohibited from recommending the drug; for companies that market products for pets; and for pet owners, who must take their chances, not knowing what chemicals might be mixed into a product they buy or how much CBD it really contains.
CBD oils, gummies, chews…”bath bombs”
It was the Farm Bill, which authorized the sale and use of hemp-derived products that contained less than .3 percent THC, that opened the door for the burgeoning CBD market. There was soon a proliferation of CBD tinctures, oils, gummies, chews, capsules, salves, drinks and other products for human (one website advertises CBD “bath bombs”) —and an abundance of claims about their health-enhancing abilities. The pet industry quickly followed suit., pet owners justified the industry’s optimism. In a 2021 survey of 1448 pet owners by Leafreport, a firm that provides analysis and research for the CBD industry, half said they had given CBD to their dogs or cats. A smaller but more rigorous 2019 survey of dog owners in Canada, led by Lori Kogan, a professor of clinical sciences at Colorado State University’s College of Veterinary Medicine and Biomedical Sciences, found an even higher number 79.8 percent. The owners in the study, published in The Canadian Veterinary Journal, said they bought the products to treat anxiety, pain, inflammation, seizures or other conditions in their dogs.
Mark Greenfield, a physical therapist and personal trainer in Manhattan, said he and his wife sometimes give CBD to Sheldon, their almost two-year-old Bichpoo, to calm him down. “He’s so high energy sometimes, he doesn’t know how to turn things off,” Greenfield said. “Sometimes at night when we all need a break, or during the day when it seems as if he just can’t calm down or is a little wired or stressed, we’ll give it to him. He has four, five, six hours of exercise, but he’s still at it, he’ll bark at us and want to play.” He added that at first, they gave Sheldon CBD-infused treats, but he stopped eating them, so they switched to packets of CBD peanut butter they found at a local pet store. Like many pet owners, Greenfield said he believes CBD worked for Sheldon, “It definitely has an impact on him.”
Yet the sale and use of cannabis products has also created new problems for pet owners and the veterinarians they rely on to keep their pets healthy. Research on the effectiveness and safety of cannabis for pets is scant, and only a handful of the studies have been submitted to peer-review, leaving many veterinarians leery of CBD or marijuana products when so little is known. Studies that do exist have found that THC, at least in large concentrations, can be toxic for dogs, who are more sensitive to the compound than humans, but whether smaller doses can be safe and effective is far from clear.
CBD, however, appears to be relatively safe, although at least one study found elevated liver enzymes in dogs given the drug, and there were other milder side effects like diarrhea or vomiting. But, a 2020 review of cannabis studies in dogs, published in the journal of the American Veterinary Medical Association (AVMA), found evidence that CBD was effective in treating seizures and pain from osteoarthritis in dogs.
The dearth of extensive research has not stopped cannabis companies from making extravagant claims about their products’ ability to treat a host of illnesses. Dr. Trina Hazzah, co-founder and president of the Veterinary Cannabis Society, said she has seen companies making unproven claims for their products’ effectiveness in treating a variety of illnesses, including cancer. The companies, she said, often use studies of mice to back up their assertions. But, she said, “You can’t translate from a mouse study to a dog that has cancer.”
CBD-related cases reported to the ASPCA’s Animal Poison Control Center rose dramatically —from 65 cases to 662 cases — in the five years from 2017 to 2021, according to Savee Daigo, a spokeswoman for the center. She said the center would not be able to provide a breakdown indicating the species of the pets or whether they ingested CBD products intended for pets or humans.
Veterinarians say that part of the problem is that the universe of cannabis-derived products for pets is virtually unregulated. The FDA, which in 2018 approved Epidiolex, a CBD solution, as a treatment for people with rare and severe forms of epilepsy, has yet to approve any other CBD products, which are considered drugs, as a treatment for pets or humans.
The FDA declined comment when asked for a timeline for when other cannabis-derived products might be approved. But an emailed statement provided by Anne Norris, an agency spokeswoman, said, “We want to stress that the FDA has not approved cannabis for any use in animals and the agency cannot ensure the safety or effectiveness of these products. For these reasons, the FDA cautions pet-owners against the use of such products.” In 2015 and 2016 the FDA conducted analyses, published on its website, of more than three dozen cannabis-derived products containing CBD, some aimed at pets, and found that many contained higher or lower concentrations of CBD than their labeling claimed. No analyses have been published for subsequent years, but the statement Norris provided to The Canine Review said that the agency is continuing to do research on CBD products.
Preliminary results of a two-phase “marketing and sampling” study it is conducting, the statement said, indicated that “fewer than half of the tested products which presented label claims contained CBD at concentrations within 20% of their claimed amount, and some contained psychoactive, intoxicating cannabinoid THC.”
The disconnect between federal and state regulations and the explosion of CBD products in the marketplace is frustrating for veterinarians, who are often asked about CBD products by their clients. Because neither medical marijuana laws nor the 2018 Farm Bill contain language specific to animals, many states—including Colorado, where marijuana is legal for recreational use by humans— prohibit veterinarians from recommending or prescribing CBD for their nonhuman patients. In some cases, licensing boards even forbid vets to discuss CBD with their clients. And while at least four states — California, Michigan, Nevada and Utah — have tried to remedy this legal absurdity by passing laws that allow veterinarians to discuss or recommend CBD, veterinarians in most states, whether fearful of losing their licenses of the limited scientific evidence, avoid doing so, or do so very quietly.
Michael San Philippo, a spokesman for the American Veterinary Medical Association (AVMA), said the Association did not “have anyone available” to comment on the use of cannabis-derived products for pets and directed The Canine Review to the organization’s website, where it warns veterinarians, in bold type, that “state laws legalizing [cannabis] use in people do not apply to cannabis use in animals.” The website also notes that “although cannabinoids such as CBD appear to hold therapeutic promise in areas such as the treatment of epilepsy and the management of pain and inflammation associated with osteoarthritis, the available scientific evidence pertaining to their use in animals is currently limited.” In 2019, the AVMA’s website says, the organization urged the FDA “to provide regulatory clarity about expectations for the labeling, safety, and use of cannabis-derived and cannabis-related products.”
Dr. Hazzah , the co-founder and president of the Veterinary Cannabis Society, said the AVMA has to “ride a very fine line because they want to stay legally sound but at the same time the organization clearly is supposed to support veterinarians.” But other veterinarians say that without clearer guidelines, they are flying blind as to what they can and can’t do.
Kogan, of Colorado State, found in a different survey of veterinarians, that “participants felt their state veterinary associations and veterinary boards did not provide sufficient guidance for them to practice within applicable laws.” “You can go into any store and buy cannabis products for your pet, but you can’t talk about it,” Kogan said. “No wonder people are confused.”
