tobacco product

Tobacco products, particularly cigarettes, have evolved from being viewed with suspicion to being recognized as a major cause of death and disease worldwide. These products are highly addictive, primarily due to nicotine, and contain over 4,000 chemical compounds, many of which are toxic.12

Key constituents of tobacco smoke include nicotine, tar, carbon monoxide, and numerous carcinogens. While nicotine's primary health effect is addiction, carbon monoxide significantly strains the cardiovascular system by reducing oxygen in the blood. The harmful effects extend to non-smokers through secondhand smoke.12

Despite declining use in some regions, tobacco consumption, especially cigarette smoking, continues to increase in developing countries, leading to a projected rise in smoking-related deaths. Regulations and public health campaigns aim to discourage use and promote cessation, though nicotine's addictive nature makes quitting challenging.13
