Unattractive personal appearance (bad breath, stained teeth, dull hair and wrinkles).
actually like 75% of high school seniors said they would NOT date a smoker,
and we did a little survey thing in my class where my teacher had everyone stand up and go to one side of the room if they would never date a smoker and the others go to the side where they would date a smoker. there were only like 4 kids on the would date a smoker side, and about 25 on the other.
not so impressing?
