Pot Meds for Pets?

Whether veterinarians are ready or not, their clients’ pets may soon be cannabis customers. 

“No matter what the detractors or the opposition say, this is a foregone conclusion,” asserts Gary Richter, MS, DVM, and owner of Holistic Veterinary Care in Oakland, California. “Like it or not, cannabis is coming.”

Richter has been actively supporting California’s SB 627 legislation (Medicinal Cannabis and Medicinal Cannabis Products-Veterinary Medicine). SB 627 would repeal a ban on veterinarians recommending cannabis to their clients; similar legislation is being considered in other U.S. states. These initiatives are buttressed by medical research that shows marijuana may help dogs and cats cope with arthritis, epilepsy, anxiety, and other conditions without the side effects of traditional drugs.

Up until now, however, California veterinarians have been afraid to prescribe cannabis for ailing patients for fear of breaking federal laws and concerns over losing their professional licenses. “About 3 years ago, the veterinary medical board in California issued a memo saying that because there was no law in the state allowing veterinary use of cannabis, veterinarians were not allowed to discuss, recommend, or otherwise have anything to do with cannabis with regards to their patients or speaking to their clients about it,” Richter says. “Every veterinarian in the state was running scared because nobody wants to get in trouble with the veterinary medical board. When people asked their veterinarians, ‘Hey, I want to use cannabis for my dog; what should I do?’ the standard veterinarian response was, ‘Sorry, I can’t help you. I’m not allowed to talk to you about that.’ So people started buying cannabis from recreational dispensaries and giving it to their pets. They were doing this based on recommendations they had read online or heard from someone at the cannabis dispensary, dog park, or pet store. We inadvertently forced people to do something that was effectively irresponsible and dangerous as it pertains to medicating pets.”

In the Hands of Politicians

SB 627 is currently “in the hands of politicians,” says Richter, but he expects California Governor Gavin Newsom to sign it once some legal wrinkles, all related to recently added amendments, are resolved.

More than 30 U.S. states have legalized medical marijuana, but none of them make provisions for veterinarians treating animals. “The reality here in California is rapidly becoming the reality in many other places in the country,” says Richter. “Accessibility is no longer an issue. The social stigma associated with the use of cannabis is rapidly falling by the wayside. Because so many people now are having very personal experiences with regards to how cannabis has helped their own health or that of a friend or family member, it’s very natural that people want to have their pets benefit in the same way. All of the things that cannabis can potentially be used for in humans—pain, arthritis, seizures, nausea, anxiety—can potentially be used for in animals.”

Cannabidiol—a cannabis plant extract also known as CBD—is the main ingredient in hemp oils, chews, and other pet products that are being used by pet owners treating their animals for a variety of maladies. CBD is associated with pain relief, while THC, the ingredient in marijuana, is what’s responsible for causing people to feel “high.”

According to a 2018 survey of 1,068 dog owners by Colorado State University veterinary medicine researchers, nearly 80% of respondents said they bought hemp or marijuana products for their dogs.¹

Clinical research into CBD is also showing encouraging results. Cornell University researchers found CBD increases comfort and activity in dogs with arthritis,² while a Colorado State University randomized clinical trial of a small group of dogs with epilepsy had “promising” results.³

The Current State of Affairs

Currently, California’s Veterinary Medicine Practice Act authorizes the state veterinary board to revoke or suspend the license of a veterinarian, or to assess a fine, for discussing medicinal cannabis with a client while the veterinarian is employed by or has an agreement with a Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA) licensee and is distributing advertising for cannabis in California.

“And that’s where bills like SB 627 are coming from,” says Richter. “Veterinarians should be the ones giving people guidance on how to do this, not people with zero medical training like the guy working behind the counter at the recreational cannabis dispensary.”

Richter says that if SB 627 is not passed, pet owners will forgo veterinary medical advice and care. “From the standpoint of veterinary patients, cannabis is medicine and it should be treated like medicine,” he says. “We want medical cannabis products to be sold in medical dispensaries only. In California, a person can walk into a medical dispensary with a cannabis recommendation and buy something. That same person can walk into a recreational dispensary and buy anything they want, across the board, no questions asked. If these [veterinary] products are allowed to be sold in recreational dispensaries, it cuts the veterinarian out of the loop. What we’re telling people is that you don’t have to go to your veterinarian to find out how to do this safely and effectively; just do it yourself.”

Richter points to 2 major problems with cannabis for pets being sold in recreational dispensaries. “One is that if cannabis is used improperly, it can be problematic from the standpoint of side effects and toxicity. And secondly, if you’re tacitly encouraging people not to take their pets to the veterinarian in order for them to get medication, one wonders what other treatment options are not being discussed that could help that animal more than cannabis,” he says.

Cannabis “is not a cure-all for everything,” Richter stresses. “We have to give people the kind of guidance that they need so that they know what they should be looking for, they know what doses to give, and they know if it’s the most appropriate medication for their pet to be taking.”

Educating the Veterinary Profession

As a recent study found that client questions about cannabis were fairly common—only 8% of respondents reported that they’d never been asked about CBD products—and 66% said they’d never recommended CBD for dogs, while 12% said they “sometimes” recommend them, and just 5% said they “frequently” do.4  Richter says “that most of the veterinary profession is completely uneducated on the topic. If I could snap my fingers and make all of this legal, and veterinarians could discuss cannabis with clients, the average veterinarian wouldn’t know where to begin. There’s got to be a huge push toward continuing education and educating veterinarians.”

Veterinarians are at “an interesting and unique crossroads,” says Richter. “It’s time to set guidelines for managing cannabis in the veterinary profession. There’s no group in the world that can give people better guidance on how to use any kind of medication safely and effectively for their pets than veterinary professionals. This is what we’re trained to do.”
