Which of the following effects of smoking is an individual least likely to experience from secondhand smoke? a. a change in senses b. a change in physical appearance c. yellowing teeth d. a change in physical ability

The correct answer is C.

You are least likely to experience yellowing of the teeth from secondhand smoke. This is because you are not making physical contact with the cigarette and the nicotine and tar are not in direct contact with your teeth. Long term exposure to second hand smoke will start to give you side effects of an actual smoker such as a change in senses, change in physical appearance and change in physical ability, in the short term you will get none of these effects.
