Most of the biological adverse effects induced by JUUL aerosols were flavor-specific. By looking at volcano plots of gene expression changes specific for each inhalant, at each timepoint, we found that exposure to JUUL Mint aerosols led to increased changes over time, while effects of JUUL Mango remained relatively stable . Furthermore, upon challenge with inhaled LPS, mice whichhad been chronically exposed to JUUL Mint aerosols had a large number of gene expression changes that were disparate from those of Air controls and JUUL Mango exposed mice .

The promotion of vaping as a harm reduction aid is premature, while a 2011 review found they appear to have the potential to lower tobacco-related death and disease. Evidence to substantiate the potential of vaping to lower tobacco-related death and disease is unknown. คอยล์บุหรี่ไฟฟ้า ราคาถูก of reducing cigarette use while vaping is unclear. E-cigarettes could have an influential role in tobacco harm reduction. The authors warned against the potential harm of excessive regulation and advised health professionals to consider advising smokers who are reluctant to quit by other methods to switch to e-cigarettes as a safer alternative to smoking.

Which is less harmful?

But in fact, e-cigarettes produce an aerosol made up of tiny particles, which is different from a vapor. The mission of Juul Labs is to transition the world’s billion adult smokers away from combustible cigarettes, eliminate their use, and combat underage usage of our products. With a clear mission to Make Smoking History, NJOY offers a range of e-cigarettes and vaping devices for the millions of adult smokers looking for an alternative. Schmid served as a consultant for legal firms representing Eli Lilly, Boehringer-Ingelheim and Gilead outside the study. Benowitz received personal fees from Pfizer and Achieve Life Sciences and served as a consultant to pharmaceutical companies that market smoking cessation medications and as an expert witness in litigation against tobacco companies outside the study.

Daily JUUL inhalation for 3 months is associated with neuroinflammation

A 2014 review recommended that regulations for e-cigarettes could be similar to those for dietary supplements or cosmetic products to not limit their potential for harm reduction. A 2012 review found e-cigarettes could considerably reduce traditional cigarettes use and they likely could be used as a lower risk replacement for traditional cigarettes, but there is not enough data on their safety and efficacy to draw definite conclusions. There is no research available on vaping for reducing harm in high-risk groups such as people with mental disorders. Exposure to Mango JUUL aerosols led to 155 significant gene expression changes, while Mint JUUL aerosols led to 74 . The genes whose expression was most significantly altered included GTPases , mucins , CCL6 , and TGFb receptors (nicotine and mango flavor; Figure 6B). Moreover, fixed lung sections stained with H&E showed no difference in inflammation in the lungs at 1 and 3 months of JUUL aerosol exposure as compared to Air controls (Appendix 1—figure 4A–L).

In a finding that could inform therapeutic targets for Alzheimer’s and Parkinson’s disease, a team of Brown University neuroscientists reports on a mechanism of degeneration for the locus coeruleus region of the brain.

The first mod to replace the e-cigarette’s case to accommodate a longer-lasting battery, dubbed the “screwdriver”, was developed by Ted and Matt Rogers in 2008. Other enthusiasts built their own mods to improve functionality or aesthetics. When pictures of mods appeared at online vaping forums many people wanted them, so some mod makers produced more for sale. It is commonly stated that the modern e-cigarette was invented in 2003 by Chinese pharmacist Hon Lik, but tobacco companies had been developing nicotine aerosol generation devices since as early as 1963. Vaping correlates with smoking among young people, even in those who would otherwise be unlikely to smoke.

However, few studies have examined the effects of e-cigarette vaping on the severity of attendant respiratory diseases (Madison et al., 2019). Under homeostatic conditions, the BAL of JUUL Mango and JUUL Mint mice contains similar levels of inflammatory cytokines and chemokines at both 1 and 3 months (Figure 7A–N). Inhaled LPS is a model of Gram-negative bacterial pneumonia and acute lung injury in mice.

Vaping can cause breathing problems, organ damage, addiction and other conditions. We are thrilled that the Reviewer is as interested in these implications as we are, because we believe the neuroinflammation detected is quite frightening, particularly because it is likely to impact both behavior and mood. We have added further discussion regarding the potential consequences of inflammation in each of the organs (pages 13-18), with an emphasis on the effects of neuroinflammation on behavior and psychology. We have subdivided the Discussion section to highlight potential effects on each distinct organ. It is clear that further studies are needed to best assess potential psychological and behavioral changes induced by e-cigarette aerosol inhalation.
