Cigarette manufacturers are deliberately manipulating menthol content in their products to attract young people and to keep others addicted for life, says a new study.
Researchers from Harvard School of Public Health (HSPH) found that the tobacco industry is intentionally adjusting menthol to create a milder experience for the first time smoker.
Menthol covers the harshness and irritation of cigarettes, allowing delivery of an effective dose of nicotine, the addictive chemical in cigarettes.
"For decades, the tobacco industry has carefully manipulated menthol content not only to lure youth but also to lock in lifelong adult customers," said Howard Koh, Professor and Associate Dean for Public Health Practice at HSPH and a co-author of the paper.
A team of researchers led Jennifer M. Kreslake, a research analysis from the Tobacco Control Research Program at HSPH analyzed the internal tobacco industry documents on menthol product development, and conducted laboratory tests to measure menthol content in U.S. brands, examined market research reports
She also drew data from the 2006 National Survey on Drug Use and Health, an annual nationally representative survey among U.S. residents aged 12 years and older
The industry documents revealed that tobacco companies researched how controlling menthol levels could increase brand sales among specific groups.
The companies determined that products with higher menthol levels and stronger perceived menthol sensation suited long-term smokers of menthol cigarettes while milder brands with lower menthol levels appealed to younger smokers.
