In the last century, the view on smoking cigarettes has changed drastically. Each week, more than 105 billion cigarettes are sold, which comes to ten million cigarettes per minute. Nevertheless, these days, smoking is considered a bad habit that is injurious to health of the smoker and to the individuals around him or her. Many public buildings prohibit the cigarette smoking, and cigarettes aren’t advertised anywhere anymore.
Cigarettes contain nitrogen oxide, carbon monoxide, formaldehyde, ammonia, and arsenic. Smoking a single cigarette reduces the life expectancy by 10.7 minutes, so a pack of 20 cigarettes shortens the existence by more than three and half hours. In most key brands, the nicotine content is on the rise, and in some well-known brands, it has been raised by as much as 11%. Cigarettes include formaldehyde, arsenic, nitrogen oxide, hydrogen cyanide, ammonia, carbon monoxide and 43 recognized carcinogens.
