Reported side effects include nose bleeds, change in bronchial gene expression, release of cytokines and proinflammatory mediators, and increase in allergic airway inflammation which can exacerbate asthmatic symptoms, thus elevating infiltration of inflammatory cells including eosinophils into airways.

The health effects of long-term nicotine use is unknown. [18] It may be decades before the long-term health effects of nicotine e-cigarette aerosol inhalation is known. [19] Short-term nicotine use excites the autonomic ganglia nerves and autonomic nerves, but chronic use seems to induce negative effects on endothelial cells. [20]
[15] [16] One issue is the need to separate the effects of vaping from the effects of smoking among users who both vape and smoke. [note 4] [17] E-cigarettes containing nicotine are more effective than nicotine replacement therapy (NRT) for smoking cessation. [18] [19] Vaping is likely far less harmful than smoking, but still harmful.
Among high-school students, the number reporting frequent use rose from 3.2% in 2015 to 8.1% in 2021, and the percentage who said they’d ever used a vaping product increased from 41.7 to 45.1 ...
The California Department of Public Health surveyed more than 31,000 high school students last year for the California Youth Tobacco Survey and found that 21.6% of them reported trying a tobacco ...
Austin Adams, now 18, asked his mother, 45-year-old Kailani Burton, to buy him a vape kit in March 2018 to help him quit smoking, a request which she agreed to, according to a case study published ...
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
These effects are primarily mediated through nicotinic acetylcholine receptors (nAChRs), particularly the α7 subtype, and to a lesser extent, β-adrenergic receptors (β-ARs). Activation of these receptors triggers several signaling cascades crucial in cancer biology, notably the MAPK/ERK pathway , PI3K/AKT pathway , and JAK-STAT signaling .
