Passive smoker

Passive smoker is anyone who can indirectly inhale or come into contact with cigarette smoke and, consequently, with the harmful substances that make it up. A passive smoker can take as many risks as the smoker himself, and that is where our best friends, the pets, come in.

It is customary for companion animals to always tend to be together with their owners, in whatever situations or environments they may be. For them, the important thing is to share every second next to their great idol.

The air in an environment where a smoker is found can contain three times the amount of nicotine and carbon monoxide and up to 50 times more carcinogens than the smoke that the smoker himself inhales. This is explained by the presence of the cigarette filter that ends up filtering most of these compounds. Read on to learn more about the subject “animals – passive smokers”.

Risks that passive smokers

If we look at the respiratory system of animals, we will see that it is very similar to humans, and so it is not difficult to understand that they too can suffer the same damage to their health as a smoker. Like humans, animals in a cigarette smoke environment are also inhaling and coming in contact with all the substances present and these substances will, over time, cause damage to the body.


Irritations are typical clinical signs of passive smoking animals: cough, eye irritation, conjunctivitis and poor appetite due to nausea, and may be the first manifestations of exposure to cigarette smoke. These signs may be more severe when the environment where the animal is located is closed or when the concentration of smoke is high, as is the case of passive smoking animals.

Pulmonary Diseases

The appearance of diseases of the respiratory tract is common in these animals, with different types of clinical manifestations due to the accumulation of toxic substances in the lungs and by the alteration of the normal functioning of the respiratory organs. The Bronchitis and Asthma are complications that usually appear in the long run and if not treated in time can become severe and sometimes even fatal. Check out the symptoms and treatment of asthma in cats in this other article.


This dreaded disease that can also affect pets can also be a consequence of inhaling the smoke for a long period of time. By accumulating toxic compounds in the lungs the genetic material of the cells can undergo an alteration, causing a disorderly and uncontrolled growth of the same, leading to the formation of malignant tumors.

Chronic Sinusitis

Chronic sinusitis is very common in people smokers due to the destruction of respiratory mucosa cells by the toxic compounds of cigarette smoke, and would not be different in animals. The respiratory mucosa of the animals is more sensitive, thus becoming more susceptible to the onset of sinusitis and related complications.

Cardiovascular Changes

Just as a smoker tends to develop cardiovascular disease due to smoking, passive smoking animals as well. Over time, the heart tends to have more difficulty pumping blood and the arteries become less elastic, these changes lead to heart failure and also vascular, and can be complicated by other factors such as age and concomitant diseases.

How to avoid

The most correct would be to cut the evil at the root, abandoning the cigarette – your health and that of your pet would be improved, and much. However, when this alternative is not possible, it is always advised to keep the animal away while smoking, and to perform this act in an open and ventilated environment, in order not to concentrate the smoke inside the house.

Another important factor is to always keep the furniture clean, as toxic substances can accumulate on flat surfaces that animals can have direct contact through the skin or by licking. Now that you know that pets are also passive smokers, do not hesitate to protect your best friend from this worldwide problem!
