State Attorney General David Louie joined 38 other Attorneys General in sending a letter urging the Federal Drug Administration to place restrictions on the advertising, and ingredients of electronic cigarettes.  E-cigs are battery-operated products that heat liquid nicotine derived from tobacco plants into a vapor that is inhaled. E-cig manufacturers are using marketing techniques similar to those used by big tobacco companies to lure new smokers.  There are no federal age restrictions preventing children from using e-cigs. However, this year, the Hawaii State Legislature passed a law prohibiting the sale of e-cigarettes to those under the age of 18. Despite Hawaii's proactive approach, Louie believes that participating in the nationwide effort to regulate e-cigarettes is critical to ensuring Hawaii's youth are protected from manufacters' efforts to make e-cigarettes attractive and easily accessible
