Marijuana, (the dried form of the Cannabis plant) has been in use for thousands of years. Interestingly, the first documented case of its use was in 2800 BC, when it was listed in Emperor Shen Nung's (father of Chinese medicine and agriculture) pharmacopeia. The plant contains over 400 chemical compounds including delta-9-tetrahydrocannabinol (THC, the major psychoactive component), and cannabidiol (CBD, a phytocannabinoid) . Over the past three decades, marijuana has gained increased popularity and has now been legalized for medicinal and/or recreational use in several states in the U.S.

As more states legalize marijuana, the availability of the drug has increased. Lamentably, so have reports of accidental marijuana poisoning in dogs. Consequently, you may be wondering can dogs get high from marijuana exposure? Yes, dogs can get high from marijuana ingestion or inhalation. More importantly, all forms of cannabis are toxic to dogs.

Cannabis can cause various symptoms in dogs, these range from drowsiness to seizures. Thankfully, marijuana poisoning is rarely fatal in dogs if they receive appropriate treatment. However, it can be serious. For this reason, whether you keep marijuana at home or are just a concerned pet parent, it is vital to understand the effects of cannabis intoxication on your pet. In this article, we will discuss all you need to know about dogs and marijuana. We will cover the following;

  • What to do if your dog consumes marijuana.

  • How to prevent marijuana toxicity in dogs.

What Are the Effects of Marijuana on Dogs?

The worrying effects of marijuana in dogs can be attributed to THC, which we earlier mentioned is the major psychoactive substance in marijuana. Here's how it works. Dogs have more cannabinoid or marijuana receptors in their brains than people do, as a result, they are susceptible to more severe reactions to marijuana. So, the amount of marijuana that may just give you a slight buzz can make your dog sick.


When a dog eats or inhales marijuana, it enters the bloodstream and is carried to the brain where it meddles with the brain's chemical messengers. Eventually, this produces the dramatic manifestations of marijuana toxicosis.

How Can Dogs Get High from Marijuana?

Dogs can get high on marijuana in various ways. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), the consumption of marijuana-infused edibles like brownies, chips, candies, and chocolate is the most common cause of cannabis toxicity. This is because marijuana-laced edibles smell and taste just like regular ones, and your dog may not be able to resist taking a bite.


Secondhand smoke is another way dogs can get high on marijuana. This means that if your pet is present in the same room with someone who's smoking a joint, they may develop marijuana poisoning if they inhale a lot of it. Likewise, eating a carelessly disposed smoked joint or ingesting marijuana-containing feces are other ways dogs can get high from cannabis.

What Are the Symptoms of Marijuana Intoxication in Dogs?

Symptoms of marijuana intoxication in dogs

The symptoms of marijuana toxicosis typically start showing within an hour. Nonetheless, you may notice symptoms faster if your dog inhales the marijuana or if they eat it along with other problematic substances like chocolate (causes vomiting, hyperactivity, and increased heart rate) or xylitol (causes dangerously low blood sugar, liver damage, and even seizures).


Generally, the symptoms start to dwindle within 18 to 36 hours and will vary in severity depending on your dog's age, weight, and health status. Here are some signs that you may notice in your dog following accidental exposure to marijuana.

  • Lethargy

  • Sleepiness or sedation

  • Vocalization

  • Excessive drooling

  • Vomiting

  • Dilated pupils

  • Anxiety or disorientation

  • Loss of coordination

  • Increased or decreased heart rate

  • Low or high body temperature

  • Urinary incontinence

  • Tremors

  • Seizures

  • Coma

What to Do if Your Dog Ingests Marijuana

If you suspect your dog has gotten into your marijuana stash or eaten some of your marijuana-infused edibles, you must consult your veterinarian immediately for proper treatment. Additionally, try to ascertain how much or what form of marijuana your pet consumed. This will help your veterinarian determine the best treatment approach for your pet. Likewise, if your pet consumed marijuana in combination with chocolate or other goodies containing xylitol, be sure to let your vet know as these substances tend to produce more severe symptoms.


The treatment of marijuana poisoning is symptomatic. If your pet recently ingested the marijuana, your veterinarian may consider inducing vomiting. This procedure would be dangerous if your pet was sedated and should never be attempted at home. Another early treatment option is the administration of activated charcoal to bind toxins.


If your pet's symptoms are mild, the veterinarian may just place them on supportive care, like administering IV fluids and temperature control (warming up or cooling down) until the drug's effects wear off. In severe cases, your vet may consider administering an enema or pumping your pet's stomach to reduce toxin absorption.

How to Prevent Marijuana Toxicity in Dogs

Now that you know the answer to the question, 'Can dogs get high to marijuana?' it is important to understand how to prevent marijuana toxicity. Responsible pet owners must protect their dogs from exposure to toxic or problematic substances like marijuana and other drugs. Here are a few tips that will help you prevent accidental marijuana exposure and poisoning in your dog.

  • Store all forms of cannabis in tight containers, high cabinets, or locked drawers to prevent your pet from accessing them.

  • Avoid leaving marijuana-laced edibles in plain sight and ensure your pet cannot reach them.

  • Dispose of marijuana waste properly to prevent accidental ingestion by your pet.

  • Ensure your dog stays in a separate room with good ventilation if marijuana is being smoked or vaped.

  • Learn as much as you can about the dangers of marijuana in pets, and when dogs get high on marijuana, and educate the members of your household on the responsible use of marijuana products.

  • Consult your veterinarian immediately if your dog shows signs of cannabis toxicity.

Conclusion

Dogs can get high from marijuana when they inhale marijuana smoke or eat marijuana edibles. Additionally, the toxicity risk is greater if they consume marijuana in combination with other concerning substances like chocolate or xylitol. While marijuana toxicity is rarely life-threatening, it can be serious. Please take precautions so that your dog isn't exposed to it.


Symptoms of marijuana toxicity include lethargy, excessive drooling, sedation, urinary incontinence, and seizures. To prevent your dog from getting high on marijuana, keep all forms of cannabis including marijuana-laced baked goods out of reach. Finally, consult your veterinarian for proper treatment if you suspect your dog has consumed marijuana.

What's the recommended dosage for my dog?

We have a recommended dosage schedule based on Veterinarian's advice This information can be found on the back of all our product's packaging. Different dogs (of different weight and sizes) would require different dosages.


The rule of thumb for our bottles is to use 0.25ml per 10lbs of body weight, or 0.025ml per 1lbs of body weight. OR 0.5mg of CBD per 1lb of body weight.


So, if you're using the oil - to find your unique dosage, you can simply multiply 0.025ml with your dog's body weight.

  • For example, if my dog weighs 62lbs, I would simply take 62 x 0.025ml = 1.55ml

As you can see, the recommended dosage would be ~ 1.55ml. However, you can start with half the dosage and slowly increase your way to the point where your dog finds relief.

So, if you're using the chews - bear in mind each chew has 25mg of CBD, so in this case based on your dog's body weight of 62lbs.

  • Simply take 0.5mg x 62 = 31mg of CBD
  • Which means your dog can take 1.2 ~ 1.5 chews.


Some dogs find relief with a lower dose, and some might need a higher dose. Every dog is unique, and there's no hard rule. This rule of thumb is here to give you a framework.


Dosing is more of an art not a science. There's no hard rule on the exact amount. Different dogs react differently, but it's always best practice to start off at a lower dosage and adjust accordingly. Give your dog's body to adapt. If your dog is having digestive upsets, it's likely because you're giving them too much, too soon. 

Will these products make my pet 'high'?

Absolutely not! It's not possible for dogs to get 'high' off our CBD as they contain less than 0.3% THC, which won't cause any intoxicating effects. However, your pup might seem a lot more relaxed, and might be sleeping more - which is a healthy sign! Keep in mind that young puppies and senior dogs should be sleeping for up to 18-20 hours of their day, while adult dogs sleep approximately 16 hours.


The lack of quality sleep can affect their health and anxiety in many ways.


CBD can make older pooches act ‘puppy-like’ and nervous young pups feel calm. The ingredients that makeup hemp contribute to a balanced mood, resulting in a sense of relaxation for your pet.
