It’s a public health issue on the same order of magnitude as COVID-19, but happening every year: “Cigarette smoking is responsible for more than 480,000 deaths per year in the United States, including more than 41,000 deaths resulting from secondhand smoke exposure. This is about one in five deaths annually, or 1,300 deaths every day.” [0] [0] https://www.cdc.gov/tobacco/data_statistics/fact_sheets/fast...

If someone near you is smoking, so are you.
