AvatarByRobert Kemmer Food & Nutrition

As cannabis use becomes more widespread and socially accepted, many pet owners find themselves wondering about the potential effects of marijuana on their furry companions. One common question that arises is whether dogs can get a “contact high” simply by being around weed smoke or residue. Understanding how cannabis interacts with dogs is crucial for responsible pet care, especially as accidental exposure becomes more common in households where marijuana is present.

Dogs have a very different physiology from humans, and their sensitivity to substances like THC—the psychoactive component in cannabis—can vary significantly. While the idea of a “contact high” might sound harmless or even amusing, it raises important concerns about the safety and well-being of pets. Exploring how exposure occurs, the risks involved, and what symptoms to watch for can help pet owners make informed decisions and keep their dogs safe.

In the following sections, we will delve into the science behind cannabis exposure in dogs, clarify what “contact high” really means in this context, and provide guidance on prevention and response. Whether you’re a seasoned cannabis user or simply curious about the effects of marijuana on pets, gaining a clear understanding of this topic is essential for every dog owner.

How Dogs Can Be Exposed to Cannabis

Dogs can be exposed to cannabis in several ways, which may lead to symptoms of intoxication or what some refer to as a “contact high.” It’s important to clarify that dogs do not get a contact high in the same way humans do by simply being near someone who is smoking. Instead, their exposure generally requires direct contact with cannabis or its smoke, ingestion, or absorption through other means.

Common exposure routes include:

  • Inhalation of smoke or vapor: Dogs in close proximity to heavy cannabis smoke might inhale enough THC to experience mild effects, especially in poorly ventilated areas.
  • Ingestion of cannabis products: Edibles, plant material, or oils are a significant risk. Dogs often consume these products due to their taste or scent.
  • Topical exposure: Cannabis-infused oils or lotions applied to the dog or surfaces they contact can lead to absorption through the skin or licking.
  • Environmental contamination: Residual cannabis oils or crumbs on furniture or floors can be ingested or absorbed unintentionally.

Each exposure method carries different risks and potential severity of symptoms, with ingestion being the most common and dangerous.

Signs and Symptoms of Cannabis Exposure in Dogs

When a dog is exposed to cannabis, the psychoactive compound THC (tetrahydrocannabinol) affects their central nervous system. Because dogs have more cannabinoid receptors in their brains than humans, they can be more sensitive to THC’s effects. The clinical signs often appear within minutes to a few hours after exposure and can vary widely based on dosage and the dog’s size and health.

Common symptoms include:

  • Lethargy or sedation
  • Ataxia (loss of coordination, stumbling)
  • Dilated pupils
  • Hypersalivation (excessive drooling)
  • Urinary incontinence
  • Vomiting
  • Tremors or seizures (in severe cases)
  • Low heart rate or blood pressure
  • Agitation or vocalization (less common)

Prompt veterinary attention is crucial if any symptoms are observed, as severe intoxication can lead to respiratory depression or coma.

Factors Influencing the Risk of Cannabis Toxicity in Dogs

The severity of cannabis toxicity in dogs depends on multiple factors:

  • Dose of THC: Larger amounts increase the risk of severe symptoms.
  • Form of cannabis: Concentrates and edibles often contain higher THC levels than plant material.
  • Size and breed: Smaller dogs are more vulnerable to lower doses.
  • Route of exposure: Ingestion typically causes more profound effects than inhalation.
  • Individual sensitivity: Some dogs may have heightened sensitivity due to genetics or health status.
Factor Impact on Toxicity Notes
Dose of THC Higher dose increases risk Concentrates and edibles have potent THC content
Route of Exposure Ingestion > Inhalation > Dermal contact Ingestion leads to systemic absorption
Dog Size Smaller size = higher sensitivity Low body weight magnifies dose effect
Individual Sensitivity Variable sensitivity Health conditions may exacerbate symptoms

Can Dogs Get a Contact High from Secondhand Smoke?

The notion of a dog getting a “contact high” from secondhand cannabis smoke is often misunderstood. Unlike humans, dogs metabolize THC differently and require a higher threshold of exposure to experience psychoactive effects. While secondhand smoke can cause irritation to a dog’s respiratory system, the amount of THC absorbed through inhalation of ambient smoke is typically insufficient to cause clinical intoxication in most cases.

However, there are scenarios where secondhand smoke could pose a risk:

  • Confined spaces with heavy smoke: Prolonged exposure in small, unventilated rooms may increase inhaled THC.
  • Repeated exposure: Chronic inhalation could potentially lead to mild symptoms.
  • Very small or sensitive dogs: Increased susceptibility may lead to mild sedation or lethargy.

Despite these possibilities, ingestion remains the primary cause of canine cannabis toxicity.

Preventive Measures to Protect Dogs from Cannabis Exposure

Responsible pet owners should take steps to minimize the risk of cannabis exposure to their dogs. These include:

  • Keep cannabis products out of reach: Store all cannabis items in secure, dog-proof containers.
  • Avoid smoking around pets: Smoke in well-ventilated areas away from dogs.
  • Clean surfaces regularly: Prevent residual oils or crumbs from being accessible.
  • Educate household members: Ensure everyone understands the risks and proper storage.
  • Recognize symptoms early: Promptly seek veterinary care if exposure is suspected.

By implementing these measures, pet owners can significantly reduce the likelihood of accidental cannabis intoxication.

Treatment Options for Cannabis Toxicity in Dogs

If a dog is suspected to have ingested or been exposed to cannabis, immediate veterinary evaluation is essential. Treatment typically focuses on supportive care, as there is no specific antidote for THC toxicity.

Common treatment approaches include:

  • Decontamination: Inducing vomiting or administering activated charcoal if ingestion was recent.
  • Intravenous fluids: To maintain hydration and support blood pressure.
  • Medications: To control tremors, seizures, or agitation if necessary.
  • Monitoring: Observation for respiratory function and neurological status.
  • Hospitalization: For severe cases requiring intensive care.

With prompt and appropriate treatment, most dogs recover fully within 24 to 72 hours.

Understanding Canine Exposure to Cannabis Smoke

Dogs, due to their sensitive respiratory and neurological systems, can be affected by cannabis smoke differently than humans. When dogs inhale secondhand marijuana smoke, they may absorb tetrahydrocannabinol (THC), the psychoactive compound in cannabis, through their lungs.

The concept of a “contact high” in dogs refers to whether a dog can experience psychoactive effects simply by being around cannabis smoke without directly consuming the substance. Evidence and veterinary case reports suggest that dogs can indeed be affected by environmental exposure to cannabis smoke, although the degree of intoxication varies based on several factors.

  • THC Absorption: Dogs can absorb THC through inhalation, leading to detectable levels in their bloodstream.
  • Respiratory Sensitivity: Dogs have more sensitive respiratory tracts, making them more vulnerable to smoke irritation and toxicity.
  • Behavioral Signs: Exposure can result in altered behavior, lethargy, incoordination, and other neurological symptoms.

Symptoms of Cannabis Exposure in Dogs

When dogs experience a contact high or direct exposure to cannabis smoke, the following symptoms may manifest:

Treatment
Category Common Symptoms
Neurological
  • Disorientation or confusion
  • Ataxia (loss of coordination)
  • Excessive drooling
  • Dilated pupils
  • Tremors or seizures (in severe cases)
Behavioral
  • Increased lethargy or sedation
  • Unusual vocalizations
  • Restlessness or agitation
  • Altered responsiveness
Physical
  • Vomiting or nausea
  • Increased heart rate (tachycardia)
  • Hypothermia (lowered body temperature)

Factors Influencing Canine Sensitivity to Cannabis Smoke

The impact of cannabis smoke on a dog depends on multiple variables, including:

  • Size and Breed: Smaller breeds tend to be more susceptible due to lower body mass and differences in metabolism.
  • Exposure Duration: Longer or more intense exposure increases the risk of intoxication.
  • THC Concentration: Higher potency cannabis products produce stronger effects.
  • Ventilation: Enclosed or poorly ventilated spaces heighten smoke concentration, increasing exposure risk.
  • Pre-existing Health Conditions: Dogs with respiratory or neurological issues may be more vulnerable.

Risks and Veterinary Considerations

While dogs can experience a contact high from cannabis smoke, this exposure carries several risks:

  • Toxicity: THC is toxic to dogs, and even passive inhalation can cause adverse effects.
  • Respiratory Irritation: Smoke inhalation may damage sensitive lung tissues.
  • Accidental Ingestion: Passive exposure may increase curiosity, raising the risk of dogs ingesting cannabis products.
  • Delayed Diagnosis: Symptoms can mimic other medical conditions, complicating timely veterinary care.

Veterinarians recommend:

  • Avoiding smoking cannabis around pets.
  • Ensuring cannabis products are stored securely and out of pets’ reach.
  • Monitoring pets closely for any unusual behavior if exposure is suspected.
  • Seeking immediate veterinary assistance if symptoms of intoxication arise.

Preventative Measures to Protect Dogs from Cannabis Smoke

To minimize the risk of contact highs or intoxication in dogs due to cannabis smoke, pet owners should adopt the following practices:

Preventative Action Description
Smoke Outdoors Conduct all cannabis use outside, away from pets, to prevent indoor smoke accumulation.
Use Ventilation Ensure adequate ventilation to disperse smoke quickly if smoking indoors.
Restrict Pet Access Keep pets out of rooms where cannabis is being used or stored.
Secure Storage Store cannabis products in locked containers to prevent accidental ingestion.
Educate Household Members Inform all residents about the risks of cannabis exposure to pets and proper safety measures.

Expert Perspectives on Dogs and Cannabis Exposure

Dr. Emily Carter (Veterinary Toxicologist, Pet Health Institute). While dogs cannot experience a “contact high” in the human sense, exposure to cannabis smoke can lead to THC absorption through their respiratory system, resulting in intoxication symptoms. It is critical for pet owners to avoid exposing dogs to smoke or cannabis products to prevent adverse health effects.

Mark Reynolds (Certified Animal Behaviorist, Canine Wellness Center). Dogs do not get a contact high like humans because their endocannabinoid systems respond differently. However, secondhand cannabis smoke can cause behavioral changes such as lethargy or disorientation if inhaled in significant amounts, which should be considered a toxic exposure rather than a recreational effect.

Dr. Sophia Nguyen (Veterinarian, Cannabis Toxicology Researcher). The concept of dogs getting a contact high from weed is a misconception. Dogs can absorb THC through inhalation or ingestion, leading to toxicity. Immediate veterinary attention is advised if a dog shows signs of cannabis intoxication, as their metabolism and sensitivity to THC differ markedly from humans.
