Alternatively, our study may be underpowered to detect subtle differences induced by JUUL vaping. Furthermore, our study only assessed the impact of daily JUUL aerosol inhalation for 1 and 3 month-long exposures and thus cannot ensure that other effects may be seen with more chronic, 6–12 month, exposures. A small number of studies have looked at whether using e-cigarettes reduces the number of cigarettes smokers consume. E-cigarette use may decrease the number of cigarettes smoked, but smoking just one to four cigarettes daily greatly increases the risk of cardiovascular disease compared to not smoking. The extent to which decreasing cigarette smoking with vaping leads to quitting is unknown.


Altria acquired a 30% stake in Juul Labs.Nu Mark, LLCMarkTen, Green SmokeJapan Tobacco InternationalPloomE-lites LOGICInternational tobacco companies dismissed e-cigarettes as a fad at first. However, recognizing the development of a potential new market sector that could render traditional tobacco products obsolete, they began to produce and market their own brands of e-cigarettes and acquire existing e-cigarette companies. Blu eCigs, a prominent US e-cigarette manufacturer, was acquired by Lorillard Inc. for $135 million in April 2012. British American Tobacco was the first tobacco business to sell e-cigarettes in the UK. On บุหรี่ไฟฟ้า Voopoo , Altria Group, Inc. acquired popular e-cigarette brand Green Smoke for $110 million. The deal was finalized in April 2014 for $110 million with $20 million in incentive payments.

Ethyl maltol concentrations have been shown to be highest in Mango pods (1 mg/ml), while menthol concentrations are highest in cool Mint pods (10 mg/ml) (Omaiye et al., 2019). The most remarkable variations we observed were in response to acute lung injury through LPS challenge, where significantly higher levels of cardiac inflammatory genes were seen in mice exposed to Mint relative to Mango and controls. In the brain, inhalation of JUUL Mint aerosols led to higher Tnfa and Il1bin the NAc-shell relative to JUUL Mango. Mint aerosols are highly similar to menthol aerosols and previous studies have shown greater increases in neuronal nAChR receptors after exposure to nicotine with menthol relative to nicotine exposure alone (Henderson et al., 2017). As a result, we surmise that the flavoring compound menthol in ‘Cool Mint’ could be a factor in the differences seen in the effects of Mint vs Mango.

In August 2016, the US FDA extended its regulatory power to include e-cigarettes, cigars, and “all other tobacco products”. Corticotropin-releasing factor, Neuropeptide Y, orexins, and norepinephrine are involved in nicotine addiction. Continuous exposure to nicotine can cause an increase in the number of nicotinic receptors, which is believed to be a result of receptor desensitization and subsequent receptor upregulation. Long-term exposure to nicotine can also result in downregulation of glutamate transporter 1.

In 2007 British entrepreneurs Umer and Tariq Sheikh invented the cartomizer. This is a mechanism that integrates the heating coil into the liquid chamber. They launched this new device in the UK in 2008 under their Gamucci brand and the design is now widely adopted by most “cigalike” brands. Other users tinkered with various parts to produce more satisfactory homemade devices, and the hobby of “modding” was born.

Mice were exposed to either e-cigarette aerosol created from Mango JUUL pods or Mint JUUL pods containing 5% nicotinic salts (59 mg/ml) using the InExpose system . Air control mice were placed in an identical chamber for the same amount of time but inhaled room air only. A 3-D printed adapter was created to produce a tight fit for the JUUL device . A negative pressure of 2 L/s was used to activate the e-cigarette for 4 s followed by 16 s of room air at 2 L/s. All experiments were conducted with approval of the UCSD Institutional Animal Care and Use Committee . The IQOS is a heated tobacco product marketed by Philip Morris International.

Notably, because Mint and Mango effects differed, several of our findings point to a ‘non-nicotine’ chemical flavorant component of the JUUL device that may be driving inflammatory changes in the brain. Recent study into the effects of vaping on the blood brain barrier lends further support to this theory, as pro-inflammatory changes were observed, partly independent of nicotine content (Heldt et al., 2020). The use of e-cigarettes or ‘vaping’ has become widespread, particularly among young people and smokers trying to quit. One of the most popular e-cigarette brands is JUUL, which offers appealing flavors and a discrete design.
