E-cigarettes

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.

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.

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.

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.

New research from the Perelman School of Medicine at the University of Pennsylvania has shown nicotine-free e-cigarette vapor can have an immediate harmful effect on the body's vascular function.

A unanimous vote by San Francisco's Board of Supervisors has effectively banned the sale of e-cigarettes in the city. Pending approval by the mayor, the prohibition is the first of its kind in the United States and will commence in early 2020.

Following complete bans on e-cigarettes in countries like Brazil and Singapore, San Francisco recently proposed new legislation to essentially follow suit. What is underpinning these calls to ban vaping? Is it really a gateway for young people into using tobacco products?

As e-cigarettes rise in popularity, many researchers are working hard to understand the long-term implications of vaping on human health. A new small study has now found that e-cigarette vapor can damage key immune cells in the lung, suggesting vaping may be more harmful that previously suspected.

A new study examining the effects of "vaping" on the gut microbiome is suggesting some good news for e-cig users, with the results showing that while tobacco smoking seems to cause major changes to gut flora, those using e-cigarettes maintain similar gut bacteria diversity to non-smokers.
