Medical Cannabis for Pets


Pets are not exempt from the modern-day onslaught of disease-causing toxins and chemicals. As with humans, conventional medicine often fails them. Medical cannabis research on animals is currently limited but promising. Convincing anecdotal reports are aplenty for treating many challenging conditions, though caution is key.

With widespread legalisation and destigmatisation, information is spreading rapidly on the medicinal value of marijuana-derived products for treating a wide range of health symptoms and conditions. However, this information is understandably aimed at humans and it does not translate directly into treating our beloved pets.

Pets in the Modern World

At Medical Cannabis Dispensary South Africa (MCDSA), we understand the special, loving bonds formed between people and animals. It is no exaggeration to say that pets become part of the family – man or woman’s best friend. When they fall ill, they are completely reliant on us to notice changes in their behaviour. This may be something obvious, such as constant scratching, eye infection, walking gingerly or a painful yelp when touching a tender area.

However, we often do not realise when an underlying disease is developing because they are unable to verbalise subtle symptoms to us. Veterinarians often fall short in this regard too, with people often insisting something is wrong with their beloved pet, only for a visit to the vet proving to be expensive and unfruitful.

Like humans, our furry and non-furry companions are exposed to an onslaught of modern-day toxins and chemicals, such as pesticides, heavy metals, overuse of antibiotics, household chemicals, fluoride in drinking water, etc. Most people do not even think twice about putting down a bowl of processed, artificially-nutritious pellets or preservative-filled canned food.

It is understandable, with the daily time pressures and high cost of living in recent times. Most people struggle to feed themselves in a healthy and nutritious manner. Also, advanced marketing schemes lead us to believe that what we are feeding our animals is perfectly normal and even healthy. So, when inevitable health challenges arise, the responsibility falls on our shoulders. Pet owners agree that we must focus on the safest and most natural treatment options available.

Medical cannabis benefits many pet ailments

Marijuana as Veterinary Medicine

Veterinarians and doctors in South Africa are not allowed to prescribe medical cannabis, as it is still considered illegal for the time being. Products derived from “hemp”, however, may be considered as nutritional supplements and are, therefore, unregulated, although they are scarcely prescribed.

Research into the therapeutic effects of this plant’s compounds – including cannabinoids like THC and CBD – on humans is steadily advancing. Scientific evidence for cannabis as veterinary medicine is rare. One aspect that could be wrongly interpreted and cause over-optimism is the fact that most medicines that make it to human trials tend to be conducted on animals first. While results are promising for a host of conditions in rodent populations, it is irresponsible to assume that they correlate to other species.

What we do know is that each human and animal body has an “endocannabinoid system”, which allows for the therapeutic effects of cannabis compounds – they mimic those produced naturally by the body (read more about this in Cannabis Science). However, there is great variability in the biochemical make-up of humans and animals, as well as between different animal species.

This means that the ability of a dog, cat or horse to metabolise marijuana differs greatly from our own. Dogs, for example, have higher concentrations of CB1 receptors (the primary target for psychoactive THC) in the brain compared to humans. Also, cats are not able to tolerate the pain medications prescribed to dogs. This highlights the need for species-specific research and treatment.

What the Research Says

Bad news first: Unfortunately, early studies on cannabis and pets have focused on toxicity, rather than potential benefits. With growing legislation and the invention of highly concentrated products, incidences of accidental animal exposure to toxic quantities of THC are on the rise.

Dogs have a tendency to “wolf down” anything edible. They are the most commonly affected, usually via ingestion of edibles, with evidence dating back as far as 1978. They are prone to severe reactions to THC at large dosages, largely due to high concentrations of CB1 receptors in the brain. Symptoms almost always present as neurological (99%) and frequently as gastrointestinal (30%).

Common signs of canine exposure include:

  • Depression
  • Excessive salivation
  • Dilated pupils
  • Uncoordinated movements
  • Vomiting
  • Urinary incontinence
  • Tremors
  • Hypothermia
  • Slow heart rate

Higher dosages may additionally cause agitation, involuntary eye movements, rapid breathing and heart rate, impaired balance or movement, hyperexcitability and seizures. In one case, a dog required temporary breathing assistance after ingesting a concentrated synthetic cannabinoid product, resulting in more severe clinical signs than dogs that ingest marijuana flowers (note that synthetic products are chemically manufactured, rather than naturally extracted).

There is a case report of a cat that suffered from agitation and other unpleasant side-effects, after exposure to THC-rich cannabis smoke. Fortunately, after recovering in hospital, it made a full recovery and was able to return home.

The good news:  CBD is backed by scientific evidence as safe for animal use. One of the earliest pet studies showed this compound’s ability to treat arthritic dogs. Specifically, 2mg/kg of body weight, taken twice daily, lessened pain and improved activity in osteoarthritis cases. Given CBD’s profound effect on epilepsy and seizures in humans, this area holds promise for animal research. A recent study showed that CBD administration significantly reduced seizure frequency in dogs and more studies are inbound.

Studies on rabbits, dogs and monkeys showed cannabinoids to be a therapeutic target for reducing intraocular pressure. Faint scientific evidence also shows promise for cannabis to be used as a treatment aid for inflammation, pain, skin conditions and cancer.

Let us set the record straight: blowing toxic smoke in your pets face or attempting to get it “high” in any way is incredibly cruel and may even be harmful. It is no laughing matter. With modern advances in medical marijuana and the invention of highly-concentrated products, there is even more reason to take extreme caution and keep products safely stored, far out of reach of animals. In case of accidental exposure, act urgently and get to a veterinary clinic (a 24-hour one, if necessary).

Busting the Myth: Is Cannabis Lethal?

Information without context can be very misleading, so here are the facts. A literature search reveals that there have been reported cannabis-related deaths in two dogs, a cat and a horse. In the case of the dogs, both were rather small and consumed baked goods containing highly-concentrated THC cannabis butter along with an unknown quantity of chocolate – which is known to be toxic to dogs.

In fact, eating as much as a small bar of chocolate can have serious consequences for a small dog. Interestingly, the treatment for ingesting high THC concentrations is similar to that of ingesting chocolate – often involving forced vomiting, activated charcoal, IV fluids and monitoring. However, we are not discounting the fact that medical marijuana can be harmful in highly concentrated doses.

There have been reported deaths in a cat and a horse, although these were likely attributable to secondary causes, rather than cannabis ingestion alone. The cat’s death was likely due to cardiomyopathy complications. The horse showed signs of colic, although a necropsy was not performed to confirm cause of death. The toxicology brief concluded that “the prognosis is favourable for symptomatic animals with no complications” and that they “usually recover within 72 hours” with supportive care.

Take note: A dose does not need to be lethal in order to be toxic or harmful. Reports of toxicosis from concentrated medical THC products causing serious symptoms are a reason to be concerned. The key to safe and effective medical marijuana use in pets is to approach dosing with caution and increase intake slowly.

Keep in mind that the reported fatal dose was for dogs was more than 3000mg/kg of bodyweight. It has been reported elsewhere that doses of 3000-9000mg/kg were not fatal. Medical products are dosed carefully, one drop at a time. A high-quality 10ml tincture may contain around 3mg of cannabis concentrate per drop or 600mg THC concentrate in total. So, the minimum lethal dose for a 30kg Golden Retriever would be roughly 150 entire tinctures – an outrageous quantity.

Based on the facts, we can conclude that medical cannabis use in pets appears to be safe, when approached cautiously and dosed accurately. The toxicity of chocolate to dogs is one good reason to keep your marijuana products and chocolate stashed together, safely out of reach of animals.

Cannabis oil is safe for pets

Medical Cannabis Use in Pets

The medical marijuana journey in pets often follows the same path as it does in humans. Conventional medicine has failed or owners seek to avoid unfavourable side-effects of harmful drugs like anti-inflammatory (NSAIDs). You want what is best for your animal and that often means seeking natural alternatives.

We understand that people are desperate to ease their animals’ suffering and improve their quality of life. Our most common pet clientele are dogs, cats and horses, but we have seen our oils used on many species of all shapes and sizes – even rodents. While scientific evidence is lacking, anecdotal reports are aplenty. However, precaution is essential. The decision to use medical cannabis should always be one based on:

  1. Educated opinion – do your own research online and seek the input of a supportive, local veterinarian who understands the potential of cannabis-based therapies for treating the specific condition at hand.
  2. Risk versus reward – cannabinoid products provide natural alternatives to medicines with unwanted side-effects and may be preferable to ease an animal’s suffering, especially in the case of debilitating or terminal illness. But scientific evidence is still catching up.

CBD oil is the most popular choice for animals. It is considered safe and effective for treating various medical conditions in children and even babies, when necessary. Its vast therapeutic potential crosses all boundaries of species, age and gender. There is little doubt that future studies will show CBD to be an effective tool for treating pets with anxiety, autoimmune conditions, cancer and several other health conditions.

Crucially, CBD is non-psychoactive, meaning it does not cause the famous cannabis “high”. In fact, it is able to bind weakly to specific receptor sites (CB1) in the brain, thereby actually preventing the cannabinoid THC from causing its famed psychoactive effect. This makes high CBD, low THC strains very valuable for medicinal applications.

CBG is an up-and-coming cannabinoid that does not cause psychoactivity and offers tremendous therapeutic potential. There are many reports of pet owners using THC to successfully treat their animals. THCA is the precursor to THC and can be used as a non-psychoactive alternative – therapeutic effect without affecting the state of mind.
