All it takes is just one puff

Just a single drag on a cigarette may drag a teen into smoking addiction, a new study suggests.
Researchers say almost a third of kids interviewed who tried smoking said their first cigarette brought them a feeling of relaxation -- and two-thirds of those kids went on to become smokers. Another factor that appeared to somewhat up the risk for dependence was having seen an ad with Joe Camel -- the Camel cigarette brand's mascot between 1987 and 1997, the study found. Psychological factors -- such as being depressed and having a novelty-seeking personality -- also boosted the likelihood of addiction.
