this one you'll find hard to believe. teens who smoke e-cigarettes are likely to smoke conventional cigarettes later in their lives. we needed a study for this. there's a new government-funded study that suts just that. they interviewed teens in the los angeles area. here's what they found. in the beginning nearly one out of every ten kids said they used e-cigarettes but never tried conventional cigarettes. half a year later three in ten said they tried cigarettes or cigars. the study pointed out hookah and cigars were more popular than cigarettes in both groups. one doctor called the study the strongest evidence to date that e-cigarettes might pose a health hazard by encouraging adolescents to start smoking conventional tobacco products. this is just in los angeles. uncertain whether they'd get the same results nationwide. it is not uncertain. e-cigarettes have nicotine in them. they don't have tobacco, they have nicotine. that's the part you get addicted
