Back in February 2014, Ohio became the first state to prohibit the sale of e-cigarettes to minors. Since then, 40 other states and cities have followed suit. Despite those regulations, a new study found it’s increasingly easy for teens to skirt the rules by purchasing the products online. USA Today reports that a new study published in JAMA Pediatrics found teens had little trouble purchasing e-cigarettes through online retailers across the country. The study, which included 11 teens ages 14 to 17, found that participants were able to buy the products in 94% of attempts. In all, only five of the 98 purchases were rejected based on consumers age.
