People attending these meetings are usually enthusiasts that use specialized, community-made products not found in convenience stores or gas stations. These products are mostly available online or in dedicated “vape” storefronts where mainstream e-cigarettes brands from the tobacco industry and larger e-cig manufacturers are not as popular. Some vape shops have a vape bar where patrons can test out different e-liquids and socialize.

“It does not mean these products are safe or ‘FDA approved.’ All tobacco products are harmful and addictive and those who do not use tobacco products should not start,” the agency said in a statement. While vaping is still unsafe, it may have benefits for some smokers who switch to e-cigarettes and stop smoking tobacco cigarettes. While flavored e-liquids or vape juice that contain nicotine may be more harmful than vapes that don’t use them, other aerosolized toxic chemicals exist in vape juice.

Long-term nicotine exposure upregulates cortical nicotinic receptors, but it also lowers the activity of the nicotinic receptors in the cortical vasodilation region. With constant use of nicotine, tolerance occurs at least partially as a result of the development of new nicotinic acetylcholine receptors in the brain. After several months of nicotine abstinence, the number of receptors go back to normal. The extent to which alterations in the brain caused by nicotine use are reversible is not fully understood. Nicotine also stimulates nicotinic acetylcholine receptors in the adrenal medulla, resulting in increased levels of epinephrine and beta-endorphin.

The enhanced chemokine induction was further elevated after 3 months of exposure to JUUL Mint . In contrast to the elevated inflammatory response to LPS observed in mice exposed to JUUL Mint, JUUL Mango exposed mice did not have enhanced expression of cytokines or chemokines. Indeed, the effects of 1 month JUUL Mint versus JUUL Mango exposure were statistically significant with regard to changes in Tnfa, Il1b, Il18, Ccl3, Cxcl2 as well as on Cxcl1 expression at both 1 and 3 months JUUL exposure (Figure 8M–N). Bacterial pneumonia and acute lung injury lead to inflammation not only in the lungs and systemic circulation, but also in the heart . It is common for patients to develop myocardial inflammation and even ischemia during lung infections (Morris, 2014; Feldman et al., 2019). Thus, we assessed the impact of acute lung injury on inflammation in cardiac tissues of JUUL exposed mice.

Elevated metal concentrations that were observed in the liquids were typically observed in the aerosols. However, there were exceptions, where only detectable aerosol metal concentrations were observed. Vuse Alto® Menthol chromium levels in liquid, for example, were below the reportable level. However, this product had the highest chromium concentration in aerosol. The Vuse Alto® Rich Tobacco was also below the reportable level in the tested liquid samples, whereas one analytical replicate had low but detectable chromium level in aerosol. Correspondingly, the highest aerosol nickel concentrations were for Vuse Alto® flavors, although they were not elevated in the liquids.
