Teenagers who smoke menthols smoke more cigarettes per day than their peers, a new Canadian study finds.

As past research suggests, menthols are more addictive than other types of cigarettes, a higher frequency of smoking was seen among nearly 5,000 adolescents in grades 9 to 12 in a nationally representative sampling Medical Daily reports.

In Canada, one in 10 high school students in grades 10 to 12 currently smoke cigarettes, with one-third of them smoking menthols. The Canadian government in 2010 banned the sale of most flavored tobacco products — including cigars and blunt wraps — with the exception of the highly popular menthols.

There is a growing concern that the high popularity of menthol cigarettes among youth may hinder the recent progress in preventing other young people from smoking because many of them may experiment with menthol rather than unflavored brands.

Likewise, menthol cigarettes remain popular in the United States as the tobacco industry spent $8.37 billion on advertising and marketing in the U.S. alone in 2010, according to the Centers for Disease Control and Prevention (CDC). Although smoking rates have declined among American teenagers during the past decade, 23.3 percent of U.S. high school students smoke cigarettes.
