Increasing addiction and intensity of e-cigarette use by US adolescents – Study

I am opposed to smoking – period. However, I understand that there are some people under the impression that smoking e-cigarettes is safer than tobacco cigarettes.

The recently released 2022 National Youth Tobacco Survey data show that 2.55 million adolescents use e-cigarettes and 27.6% of adolescents use e-cigarettes daily.

A new analysis published in JAMA Network Open by investigators at Massachusetts General Hospital (MGH) in collaboration with a retired UCSF professor reveals ongoing and worsening adolescent e-cigarette addiction in the United States.

In the analysis of data from the annual National Youth Tobacco Survey, a nationally-representative survey of middle and high school students in grades 6–12, researchers found that e-cigarette prevalence among youth peaked in 2019 then declined, but e-cigarette initiation age dropped between 2014 and 2021,and intensity of use and addiction increased after the introduction of protonated nicotine products.

Protonated nicotine is created by adding acid to the e-cigarette liquid, which makes the nicotine easier to inhale. Since Juul pioneered protonated nicotine, it has been widely adopted by other e-cigarette companies.

Reduced-nicotine cigarettes result in less smoking in anxious, depressed smokers

For the record, I am against smoking. You are better off not doing it. However, it appears that if you must, you can do it with less onerous results.

Lowering the amount of nicotine in cigarettes to non-addictive levels may reduce smoking without worsening mental health in smokers with mood or anxiety disorders, according to Penn State College of Medicine and Harvard Medical School researchers. They said reducing nicotine content in cigarettes could also lessen addiction, lower exposure to toxicants and increase a smoker’s chances of quitting.

Tobacco remains the leading preventable cause of premature death and disease in the United States. Recent proposals by the U.S. Food and Drug Administration and the New Zealand government seek to limit the amount of nicotine in cigarettes to minimally addictive levels. Prior research indicates that reducing nicotine content could help smokers quit, but there is little evidence to demonstrate if these policies could adversely affect smokers with current or prior affective disorders like depression and anxiety disorders — which affect an estimated 38% of U.S. cigarette smokers.

JUUL delivers substantially more nicotine than previous generation e-cigs and cigarettes – Study

The study, which appears online Jan. 4, 2020, in Tobacco Regulatory Science, found that nicotine concentrations were five to eight times higher in rodents that were exposed to JUUL versus other tobacco products. The work also supports an earlier finding by the same researchers of harm to blood vessels from brief exposures to both direct and secondhand smoke from cigarettes, little cigars and combustible marijuana, and to aerosol from IQOS “heat-not-burn” tobacco products.

JUUL and earlier generation e-cigs are promoted as being less hazardous than cigarettes. Since 2016, there has been a dramatic increase in youth e-cig use, with JUUL devices particularly effective at recruiting teenagers to begin nicotine usage. A recent study found 27.5 percent of high school students and 10.5 percent of eighth graders currently use e-cigs, with more than half of both groups using JUUL as their preferred choice.
