Hi Guys,Do you know Whyof 21 in Hawaii?Here is an explanation from American Cancer Society.Tobacco products, including electronic cigarettes or e-cigs, can only be sold to people who are at least 21 years old.This is really important because we know 95 percent of lifetime smokers start before age 21 and by removing tobacco from peer groups in high schools, we’re ensuring that young people have a lesser likelihood of knowing someone over the age of 21, and will be less likely to pick up the deadly habit to begin with,” Christopher Friend, government relations director with the American Cancer Society.
