Cigarette butts, the most common garbage on the planet, are made up of cellulose acetate plastic fibers, which, despite claims by the cigarette industry, has no evidence that it protects smokers from the harms of tobacco.Worse still, a single cigarette butt can contaminate 1000,7000 liters of water and release up to 4,5 harmful chemicals, including carcinogens.Cigarette butts are often fatal, especially for fish. Microorganisms that fish feed on, which means that the effects of butts enter the human food chain.It is estimated that 2019.2021 trillion cigarette butts are discarded annually.Cigarette butts first appeared, in the fifties of the last century, when the tobacco industry portrayed them as a way to make cigarettes safer, however, according to research published in <>, in the British Medical Journal, filters do not reduce tar when people smoke. Cigarette butts are made of non-biodegradable plastic called cellulose acetate, and therefore can take decades to decompose into smaller plastic particles.The study criticized the failure to hold tobacco manufacturers responsible for the cost of the waste they generate, while excluding this concern from the WHO tobacco control convention.Based on these facts, the researchers call for a ban on the sale of filtered cigarettes, not only because they do not contain health benefits but are also a major contributor to pollution. The authors argue that the EU's ban on many single-use plastic products, starting in <>, has missed an opportunity by not including cigarette butts on that list."If we fail to reduce the trillions of cigarette butts, which are added to the global waste burden annually, we are undermining our efforts to reduce global plastic waste and missing an opportunity to help end the global tobacco epidemic," the report concluded.
