Can the exhaust gas from fireworks induce lung cancer?

First of all, there is no evidence that the exhaust gas from fireworks can induce lung cancer.

Because judging from the firecrackers. Basically, people in China only shoot during the Spring Festival, and they don't shoot at other times. So this situation will basically not happen.

Because there are many reasons for inducing lung cancer. Smoking or environmental pollution may induce lung cancer, but fireworks are not the inevitable cause of cancer.

He's an expert now. It is forbidden to set off firecrackers on the grounds that it pollutes the environment. In fact, this is not true at all. China has set off firecrackers for thousands of years. The air in China was always good decades ago. Up to now, the main factor of environmental pollution is that there are too many chemical plants and cars. It has nothing to do with fireworks.
