[...] researchers found that in 2014 people age 12 to 24 who used e-cigarettes were three times as likely to become daily cigarette smokers in the future. Among those who reported using a tobacco product, daily use increased with age through age 28. Daily cigarette smoking nearly doubled between 18 to 21 year olds (12 percent) and 25 to 28 year olds (21 percent).

"This is the first paper that actually looks at progression to dependent cigarette smoking among young adults. In these data, e-cigarettes are a gateway for those who become daily cigarette smokers," said the study's first author, John P. Pierce, [...]

Marijuana stocks are booming this week following the victories of Raphael Warnock and Jon Ossoff in Georgia's Senate election runoffs, which will give Democrats control of the presidency and both chambers of Congress.

Canopy Growth, the first marijuana stock to ever be publicly traded in North America, is up 13.2% since the election Tuesday. "This new slate of leadership presents an incredible opportunity for national cannabis reform in the United States—the beginning of the end for the long-outdated prohibition on cannabis," David Culver, U.S. Vice President of Government Relations at Canopy Growth, told [...]

Recent years have seen a rapid increase in the popularity of electronic cigarettes (e-cigarettes) among adolescents in the USA. Evidence on their role in the continuation of or abstinence from cigarette smoking among young smokers remains scarce. The data were drawn from the 2015–2018 National Youth Tobacco Survey—a nationally representative survey of US middle and high school students. Multivariable logistic regression was used to assess the association between ever e-cigarette use and past 30-day abstinence from cigarette smoking. [...]

E-cigarettes commonly known as vapes and e-hookahs, work by creating aerosols that are inhaled into the lungs through the process of heating up the contained liquid. This liquid usually consists of tetrahydrocannabinol (THC), nicotine, cannabinoid (CBD) oils, additives, and flavourings.

Researchers examined the health risks of cannabis vaping by conducting a study with 2553 young adults from Southern California. They looked at different frequencies of exposure to cannabis use in order to determine whether or not any health risks were involved.

There have been substantial recent changes in youth tobacco product use in the USA – including, notably, a rapid increase in use of e‐cigarettes. It is not known whether, and if so how far, these changes are reflected in levels of nicotine dependence. This study used data from a large, nationally‐representative sample of US adolescents to (i) estimate the annual prevalence of nicotine dependence in relation to current use of tobacco products, (ii) describe trends in dependence over time, [...]

Joe Biden and Kamala Harris will assume the offices of president and vice president at a time of great societal division as the pandemic continues to ravage the United States.

It is unsurprising, therefore, that tobacco harms have been largely overlooked amid the unfolding political drama. Yet almost half a million Americans—more even than have so far died of COVID-19—lose their lives to smoking-related causes every single year.

The impact of electronic cigarettes (ECs) on nicotine use is hotly debated: some fear that ECs are a “catalyst” to conventional smoking, while others argue they divert adolescents from the more harmful product. This study used simulation modeling to evaluate the plausibility of catalyst and diversion hypotheses against real‐world data.

Smoking traditional cigarettes in addition to using e-cigarettes results in harmful health effects similar to smoking cigarettes exclusively, according to new research published today [...] In a large data analysis of more than 7,100 U.S. adults ages 18 and older, researchers studied the association of cigarette smoking and e-cigarette use with inflammation and oxidative stress as biomarkers. Inflammation and oxidative stress are key contributors to smoking-induced cardiovascular disease and their biomarkers have been shown to be predictors of cardiovascular events, including heart attack and heart failure.

Even if you consider yourself a light or "casual" smoker, it does not necessarily mean that you have completely escaped nicotine addiction, warns new research.

Many light smokers – those who smoke one to four cigarettes per day or fewer – meet the criteria for nicotine addiction and should, therefore, be considered for treatment, said the study published in the American Journal of Preventive Medicine.

"In the past, some considered that only patients who smoke around 10 cigarettes per day or more were addicted, and I still hear that sometimes," said Jonathan Foulds, Professor at Pennsylvania State University in the US.
