Preventing Youth Smoking: Over Half of Countries Have Made No Progress

May 28, 2021 9-in-10 smokers become hooked as teens, young adults More than half of countries worldwide have shown no progress in reducing smoking among teens and young adults over the past three decades, according to findings from a study of global smoking trends involving 204 nations and territories. An analysis of Global Burden of Disease study data from 1990 through 2019 showed that 9-out-of-10 (89.1%) new smokers worldwide pick up the habit by the time they are 25, and that close to 1-in-5 (18.5%) smokers began using cigarettes regularly by age 15. Worldwide in 2019, 155 million teens and young adults between the ages of 15 and 24 years were regular combustible cigarette smokers, with a global prevalence of 20.1% among males and 4.95% among females, wrote researcher Emmanuela Gakidou, PhD, MSc, of the University of Washington Institute for Health Metrics and Evaluation, Seattle, and colleagues.

High Nicotine E-cigs Helped Smokers Cut Back on Tobacco

Apr 16, 2021 Dual users also had reduced tobacco toxicant exposures at 24 weeks Smokers using high-nicotine electronic cigarettes to cut down on their cigarette consumption were more successful in doing so than smokers given low-nicotine or no-nicotine cigarettes substitutes, and they also had lower exposures to tobacco-related carcinogens in a clinical trial with more than 500 participants followed for six months. Total urinary concentration of the tobacco toxicant 4-(methelnitrosamino)-1-(3-pyridy)-1-butanol (NNAL) was significantly reduced over 24-weeks in the smokers who used electronic nicotine delivery systems (ENDS) with nicotine delivery equivalent to combustible cigarettes. Smoking declined by 58% in the group during the period, with daily cigarette use reduced from an average of close to 18 cigarettes per day at baseline to 7.43 at 24 weeks.
