Cigarettes are a nightmare for public and environmental health. If you're trying to quit, that's the first step. But if you do smoke, please be aware that cigarette butts are not biodegradable and should be properly disposed of. There's a misconception that cigarettes break down because they're just paper and tobacco, but the reality is that there are tiny plastic particles in cigarettes. When carelessly tossed on the ground, the butts end up as pollution. Birds mistake the butts for food, and they end up ingested by marine animals. Proper disposal means throwing cigarettes in a trash receptacle. And then? Quitting.
