👉 Dealtime fumes, also known as secondhand smoke, are the harmful gases and particles released into the air when tobacco products like cigarettes, cigars, or pipes are smoked. These fumes contain over 7,000 chemicals, many of which are toxic and carcinogenic, including nicotine, carbon monoxide, and various carcinogens. Unlike secondhand smoke from active smoking, dealtime fumes can linger in indoor environments for hours, posing significant health risks to non-smokers, particularly children, the elderly, and those with respiratory conditions. Exposure can lead to respiratory issues, cardiovascular problems, and even increase the risk of certain cancers, making it crucial to avoid areas where tobacco smoke is present.
