(AP) — At least two Lincoln retailers have provided lounges for their customers to sample varieties of e-cigarettes.

Co-owner Greg Kimble at Lincoln Vapor says the lounge has been a popular feature for the “vapers,” as e-cigarette smokers are known.

The devices deliver nicotine through water vapor, rather than through tobacco smoke. Users can buy different flavorings for the cigarettes and can vary the amount of nicotine delivered in each puff.

Big Red Vapor Pleasures owner, Chad Svoboda, said the vapers “just like to hang out in our lounge area, talk vape and watch TV.”
