Answer 1

The EPA classifies environmental tobacco smoke (ETS) as a Group A carcinogen, b. known to cause cancer in humans.

Step-by-step explanation:

The EPA classifies environmental tobacco smoke (ETS) as a Group A carcinogen, which means that it is known to cause cancer in humans. Secondhand smoke, which is a combination of side-stream smoke and the mainstream

smoke that is exhaled by the smoker, has been demonstrated by numerous scientific studies to cause disease. It contains more than 7,000 substances, including at least 40 chemicals that negatively impact human health and are known to be toxic, carcinogenic, or both.
