In general, most of the cytokines detected in BALF were significantly increased in WT mice exposed to PG with nicotine compared to PG alone or air control [42]. Some of these effects were found to be through nicotine activation of NF-κB signalling albeit in females but not in males. In addition, PG with nicotine caused increased macrophage and CD4+/CD8+ T-lymphocytes cell counts in BALF compared to air control, but these effects were ameliorated when animals were sub-chronically exposed to PG alone [42]. Researchers know more about the long-term effects of smoking than those of vaping. However, vaping products contain a great deal fewer harmful chemicals than cigarettes and can be an effective tool in quitting smoking altogether.

Children and adults can develop nicotine poisoning from swallowing, breathing, or absorbing e-liquid through their skin or eyes. E-cigarette use can also result in serious injury due to defective batteries that have caused fires and explosions. Vaping and smoking both involve inhaling nicotine and other substances into the lungs. While cigarettes burn tobacco that produces smoke, e-cigarettes heat liquid to make an aerosol that often contains nicotine, various chemicals, heavy metals (nickel, tin, and lead) and small particles that can be inhaled deeply into the lungs.

A lack of data has led to classification of methylgloxal as a Group 3 carcinogen (carcinogenicity to humans not classifiable) by IARC. Both compounds have been previously detected in e-cigarette emissions at concentrations of 0.07–0.94 and 0.09–33&nbsp
