But Smith thinks UF is going too far by banning all tobacco products.
"You start taking away people's rights to do stuff, and eventually we become complacent," Smith said. "And complacency is one of the worst evils."
Smith said he doesn't think the university should interfere with something that is his personal choice.
"I'm not forcing anyone to sit near me," Smith said. "I'm not blowing smoke in other people's faces. I don't purposely smoke next to people who aren't smoking. It's just ridiculous. They're trying to mandate lifestyle."
But Orlando disagrees.
"I can understand why people might feel that way," Orlando said. "But our goal is really a lot more pure than that. It's not to 'mandate lifestyles,' it's to help lead people to live a better lifestyle."
Some students who smoke think the ban will actually benefit them.
"It's a pretty good thing for me because I want to reduce my smoking," said 25-year-old UF graduate student Chrysafis Vogiatzis.
Vogiatzis said although he knows some smokers feel it is their right to smoke, he thinks they are wrong.
"It is not exactly a right," Vogiatzis said. "A right to free air is more important for everyone. I don't think it's a right to smoke. We're not born with a cigarette in our mouths."
