E-Cigarette (Vapor) Toxicity in Dogs

Overview of E-Cigarette Toxicity in Dogs

Electronic cigarettes (commonly referred to as E-cig, personal vaporizer or Electronic cigarettes or electronic nicotine delivery system), are becoming increasingly popular and with that is an increased risk of toxicity to dogs and cats.

What are E-Cigarettes?

Electronic cigarettes are marketed as nicotine replacement products to replace smoking traditional cigarettes. E-cigarettes provide smokers with a smoke-free source of nicotine, commonly referred to as “vaping”.

E-cigs are battery-operated vaporizers in the shape of a long cigarette which simulates smoking cigarettes. The E-cigs are filled with E-liquids which contain nicotine. The liquids are purchased in cartridges – and packaged in groups of 5 to 100 cartridges.

The atomizer in the E-cigarette heats the liquid which turns it into a vapor which is then inhaled. It creates a vapor cloud that looks like cigarette smoke. The E-liquid contains a mixture of ingredients including nicotine, flavorings, glycerin and propylene glycol.

The E-cigs produce an aerosol that resembles smoke and gives the “smoker” the satisfaction of smoking. According to vaping product sales are big – in fact “last year it was projected to hit an estimated $1.7 billion dollars”.

Are E-Cigarettes Safe?

The safety of E-cigs are yet to be determined. Some evidence suggests that it may be safer but traditional smoking but data is not conclusive. Studies regarding the effects of the vapors have not been completed. goes on to say that “people may think vaping is safe, but FDA has seen no data establishing anything like that”.

The flavored e-liquid can contain 10 times the amount of nicotine as traditional cigarettes. The flavoring and aroma in the E-liquids makes them attractive and enticing to some dogs to ingest.

There are three problems with ingestion of e-cigarettes for dogs:

1. Ingestion of the plastic casing can cause a gastrointestinal obstruction
2. Oral trauma can occur from the sharp plastic when chewed and
3. Nicotine Toxicity from ingestion of the E-liquid

Ingestion of E-Cigarette E-liquids can cause nicotine toxicity.

How Much Toxicity is In an E-Cigarette Cartridge

Each E-Cigarette Cartridge contains 6 mg to 24 mg of Nicotine.

One cartridge has the nicotine equivalent of 1 to 2 regular cigarettes.

According to the, “the ingestion of a single cartridge can result in clinical signs for a 50 pound dog and potentially death for a dog less than 10 pounds.”

Signs of E-Cigarette E-Liquid Toxicity in Dogs

The clinical signs of toxicity are dependent upon the amount and the concentration of the e-liquid ingested or absorbed relative to your dog’s body weight. The E-cigarette E-Liquid can be absorbed when ingested as well as through the skin if the pet walks through spilled E-cigarette E-Liquid.

The signs of toxicity are dose-dependent and generally begin within 15 minutes to one hour of ingestion. Many dogs will vomit naturally after ingestion.

When large amounts are consumed, the effects can be life-threatening, but even small amounts can induce symptoms. Without treatment, nicotine toxicity can cause paralysis of the breathing muscles and your dog may die from an inability to breathe, sometimes within a few hours. If your pet exhibits any of the following symptoms, call your veterinarian.

Treatment of E-cigarette E-Liquid Toxicity in Dogs

The immediate treatment is to reduce the amount of nicotine in the stomach while keeping your dog alive until the nicotine is broken down by the body.

Despite treatment, some dogs that have ingested large amounts of nicotine may not survive.

Your veterinarian might do any of the following:

Prognosis for E-cigarette E-Liquid Toxicity in Dogs

The prognosis is good when small amounts are ingested and treatment is prompt and aggressive. The prognosis is poor with large ingestions. If an animal survives the first four to five hours, the prognosis is considered good. Most of the nicotine is eliminated from the body within 16 to 20 hours.

Home Care for E-cigarette E-Liquid Ingestion

If nicotine ingestion is witnessed, induction of vomiting may prevent the toxic signs of nicotine poisoning. Consult your veterinarian or local emergency facility for instructions regarding inducing vomiting at home. Once the signs of nicotine toxicity have developed, home treatment is not effective and immediate treatment by a veterinarian is encouraged.

Preventive Care

The best prevention is to eliminate the source of nicotine. Keep cigarettes, cigars, and all nicotine products out of the reach of your pets. This includes ashtrays, chewed nicotine gum and used nicotine patches. Remember, even ash and used products still have residual nicotine. The amount of ingestion required for toxicity is a lot higher than with the unused product, but the potential for toxicity is still there.
