[originaltext]M: Yael, what’s that in your hand? W: Come on, Don. Haven’t you

M: Yael, what’s that in your hand?
W: Come on, Don. Haven’t you seen a cigarette before? Every day in the United States, about 1,500 girls begin smoking, and I figured, why not do my share?        
M: But Yael, don’t you know that tobacco kills more than 140,000 women each year, and that half of those women are between the age of 35 and 69?
W: Yeah, but that’s why I smoke a brand with low nicotine and tar content.
M: Although tobacco companies advertise some cigarettes as "light," this is just an advertising strategy to obscure the risks associated with smoking—smoking a light cigarette is just as risky as smoking a regular one. In fact, research shows that people who smoke light cigarettes actually smoke differently in order to get higher levels of nicotine.
W: I didn’t know that.     
M: The one thing you can say about tobacco companies is that they are really smart about marketing. While tobacco ads that target men focus on cigarettes as macho or cool, tobacco ads that target women focus on social and political themes important to women. For example, ads will say that you’ve come a long way, or that you’ve found your voice, or encourage you to just be yourself, as if smoking has anything to do with progress and self-expression. Young women are especially easy to be influenced by these ads because addiction, disease, and premature death seem so remote to them. And the thing is, people who have smoked as few as one hundred cigarettes report having difficulty in quitting.
W: So, Don, can you pass me that ashtray?      
M: With pleasure, as long as you put it out.
