(AP) — Omaha smokers are wanted for a study of tobacco marketing’s effect.

Researchers at the University of Nebraska Medical Center and Roswell Park Cancer Institute are examining point-of-sale tobacco advertising and smoking habits. The three-year, $1.4 million study is funded by the National Cancer Institute.

Researchers are seeking about 1,000 smokers who are 18 or older, live in Omaha, have smoked more than 100 cigarettes over their lives and currently smoke five or more cigarettes a day. They’ll be asked to undertake a 30-minute telephone survey and, in six months, a 15- to 20-minute follow-up telephone survey. Participants will be compensated for their time.
