Which of the following is NOT a negative effect of tobacco use: Oral Cancers
Emphysema
Increased popularity
Unsuccessful Pregnancy
Stained Teeth

Increased popularity is the only one that makes sense but none of these sound very positive. But the rest are definite downers so it is the only one that makes sense.

Hope that helps! Have a good day!
