Connie Lau hates smoking. "It smells awful, and it's so bad for you. It breaks my heart to see my friends smoking. I try to get them to give up smoking." She says.

For starters, she can't stand smoking. But she also believes it's important for young people like her to try to make a real impact in their communities.

Every time she stops the sale of cigarettes to children, she's helping to uphold the law. "A single teenager can make a big difference," Connie says.
