"I've been in veterinary medicine for over 10 years, including several years in emergency critical care," Scott said. "Prescription medicines come with a lot of scary side effects. Our olive oil-containing CBD product offers a more natural approach."
One of the related legal issues now has to do with levels of yet another compound known by a three letter acronym: THC, which stands for tetrahydrocannabinol. It is the primary mind-altering component of cannabis. When the plant is grown for its fiber and other non-psychoactive uses, it is commonly called hemp.
Pet treats made from hemp that contain CBD, but less than .3 percent THC, can be sold at any pet store or online. Heidi Hill, a homeopathist and the owner of Holistic Hound pet store in Berkeley, offers a line of such treats made with hemp organically grown in Colorado.
"I don't smoke pot," Hill told Seeker. "It is also out of my comfort zone to give pets THC-containing products. Animals are very sensitive to it."
"But I have observed how the CBD treats have helped multiple animals, including cats," she added, before whipping out a long list of testimonials from enthusiastic clients. Hill fed her own dog Pearl the treats after the canine was diagnosed with Cushing's disease, and said they improved Pearl's appetite and quality of life.
Ahna Brutlag, a board-certified veterinary toxicologist at the Pet Poison Helpline, agrees with Hill that pets should not be exposed to THC.
"We continue to receive more and more calls about pets getting into their owner's marijuana," Brutlag told Seeker. "In fact, over the past six years, we've had a 448 percent increase. The biggest shift, for us, has been the source of marijuana to which pets are exposed."

She explained that the rising use of "medibles," edible marijuana products made for humans and not pets, pose one of the biggest dangers. They often contain chocolate, which adds an extra risk for poisoning, especially in dogs and cats. Smoking, as opposed to vaping, medical marijuana can cause problems too if the owner does this around their pet. Birds and cats can, in particular, be very sensitive to the smoke, Brutlag said.
Owners of pet pigs, rabbits, ferrets, horses, and even a kinkajou that chowed down on her caretaker's marijuana-laced brownies have all placed frantic calls to the Helpline. Symptoms vary from the animal appearing drunk to experiencing dangerously high heart rates.
"Remember that medical marijuana [meant and dosed for humans] is a medication and, like all meds, should be kept well out of reach of pets and children," she said. "Pets are opportunistic, indiscriminate eaters, so if you leave something tasty in their vicinity, don't be surprised if they eat it -- all of it."
"One of the biggest concerns with pets ingesting marijuana-laced foods is that they don't just stop with one brownie; they'll eat as many brownies as possible. This can result in serious and potentially life-threatening overdoses."
