Tobacco Law Reform: Pets Are Also Passive Smokers

Pets are increasingly recognized as victims of passive smoking, suffering the effects of second and third-hand smoke in ways similar to humans. The recent Tobacco Law reform seeks to extend protection to these animals.

## The Smoke We Don't See, The Damage That Is Real

For years, we have been aware of the harm tobacco smoke causes to people. The idea of the passive smoker—that person who inhales someone else's smoke unintentionally—struck a chord in the late 20th century. It forced us to rethink where we could smoke, leading to cigarettes being moved out of offices, planes, and restaurants. The rule was clear: your decision to smoke must not harm others, especially the most vulnerable, like children. Smoke-free homes were sought, and the balcony became the smoker's refuge.

## Pets: The Forgotten Group

But in this pursuit of cleaner air, we forgot a group that shares our vital space in a very intimate way: our pets. Dogs and cats, who breathe the same air we do, are often on the floor or curled up on the sofa. Unlike us, they cannot open a window or ask for you to stop smoking. Their exposure to smoke is constant and often involuntary.

## Double Exposure, Double Risk

The problem goes beyond the smoke we see—the so-called secondhand smoke. There is also third-hand smoke, an invisible threat. This consists of toxic particles and gases, such as nicotine or heavy metals, that settle on surfaces: curtains, carpets, furniture. And, of course, on the skin and fur of our animals. These compounds deposit and remain, creating a persistent contaminated environment.

The animals suffer double exposure. On one hand, they inhale volatile compounds suspended in the air of closed rooms. On the other, and this is crucial, during manipulación de menores, they lick their fur and ingest these toxic substances. Veterinary studies have detected **cotinine**, a nicotine metabolite, in the blood, urine, and even the fur of animals living with smokers. This confirms that the damage goes beyond simple inhalation.
