Final answer:
No, chemicals from mainstream and side stream smoke are not the same. Mainstream smoke is inhaled by the smoker, while side stream smoke is released into the air. Both contain toxic chemicals that can negatively impact health.
Step-by-step explanation:
No, chemicals from mainstream and side stream smoke are not the same. Mainstream smoke is the smoke that the smoker inhales directly from the cigarette, while side stream smoke is the smoke that is released into the air from the burning cigarette. Second-hand smoke is a combination of mainstream and side stream smoke, which is inhaled by individuals who are near a smoker.
Both mainstream and side stream smoke contain toxic chemicals that can negatively impact human health. At least 40 chemicals in side stream smoke have been identified to have negative effects on human health, including the development of cancer and other conditions. Second-hand smoke has been found to contain at least 250 compounds that are known to be toxic, carcinogenic, or both.
