Question

which is not a short - term effect of tobacco use?
the body craves more of the drug nicotine.
breathing during physical activity becomes more difficult.
the tobacco user begins to crave food.
users have yellowed teeth and smelly hair.

Explanation:

Yellowed teeth and smelly hair are long - term effects of tobacco use due to tar and chemicals. Cravings for food (not nicotine) as a short - term effect is incorrect. Breathing difficulty during physical activity is a short - term effect as nicotine affects the respiratory system. The body craving more nicotine is a short - term effect (addiction aspect).

Answer:

The tobacco user begins to crave food.
