Vaping

With the rise of vaping, a big question has been whether drugs that help cigarette smokers quit will work for e-cigarette users. The first US trial using an existing drug to help vapers quit has shown they're effective, even without ongoing counseling.

Unusually high levels of lead and uranium has been found in the urine of teenagers who frequently use e-cigarettes. But experts have warned that, due to research flaws, not enough has been done to ensure the link isn't just smoke and mirrors.

Even moderate exposure to nicotine-free vapor from e-cigarettes can literally stop the body's frontline immune cells in their tracks, reducing their ability to fight off foreign invaders, a new study has found.

Smoking is no good for your teeth, that is well-known. But what about vaping? New research from Tufts University suggests using e-cigarettes may not be that much better, finding an association between increased risk for cavities and vaping.

New research has found users of nicotine-salt-containing pod and disposable e-cigarettes display unique markers of immune suppression not seen in users of other kinds of e-cigarettes. The study indicates the long-term health implications are unknown.

Following years of regulatory delays the FDA has called for all e-cigarette products from Juul to be removed from sale in the US. The FDA cites the reason for the action as “insufficient and conflicting data” in toxicological studies submitted by Juul.

Research from the UCSD School of Medicine into the effects of chronic pod-based e-cigarette use found a variety of raised inflammatory markers in different organs depending on e-cigarette flavor, with neuroinflammation the most prominent adverse effect.

Nicotine is one of the more harmful compounds in electronic cigarette vapor, so non-vapers should avoid breathing it in whenever possible. A new skin-worn sensor could help, by monitoring airborne nicotine levels in the wearer's immediate vicinity.

A first-of-its-kind study has found traces of hundreds of unknown chemicals in electronic cigarette vaping liquid and aerosols. The study details a huge array of unidentified chemicals plus a handful of known and potentially harmful compounds.

New research suggests e-cigarette vapor alone, free of nicotine or flavoring, can trigger gut inflammation. Across a series of experiments the study demonstrated how e-cigarette vapor can weaken the gut’s lining and lead to chronic inflammation.

Two observational studies have found a link between e-cigarette use and cognitive complaints such as memory impairments and brain fog. The research doesn't present evidence of a causal link but calls for further long-term study into the relationship.

After months of concern, the CDC has revealed it's confident in claiming the “vast majority” of recent lung injury cases related to e-cigarette use can be linked to illicit THC vape liquids containing vitamin E acetate.
