Just a few feet away, members of the Carolina Cancer Focus offered them an alternative.
CCF members are promoting the Great American Smokeout all week in an effort to get people to quit smoking for at least 24 hours.
However, few UNC students seem interested, senior Jamie Shuster, president of CCF, said.
"We haven't done a survey, but college students smoke a lot," Shuster said. "It's a problem, and it makes it hard for people to pledge here."
The smokeout, sponsored by the American Cancer Society, is a nationwide effort to encourage smokers to pledge that they will not smoke Thursday.
"The hope is that those 24 hours will lead to not smoking at all," Shuster said.
The first Great American Smokeout took place in 1977. More Americans try to quit on this day than any other, including New Year's Day, according to the American Cancer Society.
CCF has been promoting the smokeout on campus since its establishment four years ago.
CCF will have a table set up in the Pit from 10 a.m. to 2 p.m. every day until Thursday.
