Propylene Glycol and Vegetable Glycerin
Propylene glycol (PG) and vegetable glycerin (VG) are usually used as bases in e-liquids, determining the thickness of the vapor and affecting the flavor as well. PG is known for producing a stronger throat hit while VG delivers a smoother experience. These substances are generally regarded as safe by the FDA when used in food, although inhalation effects are still being studied.
Nicotine Levels
Nicotine is a naturally occurring substance in tobacco plants and is included in e-cigarettes to satiate the cravings of smokers looking for an alternative to traditional cigarettes. The concentration of nicotine can range from high to zero, catering to the preferences of the user. It’s important to be aware of nicotine’s addictive nature and its potential effects on health, including elevated heart rates and blood pressure.
Flavorings and Additives
A spectrum of flavors, from menthol to fruity blends, is used to make vaping more enticing. However, recent research is investigating the possible consequences of inhaling certain flavoring chemicals typically known to be harmless when ingested. Diacetyl, a chemical used for buttery flavoring, has been identified as harmful when inhaled, associated with respiratory issues.
Potential Health Risks
Though initially marketed as safer than smoking, vaping has raised concerns about lung health, especially among young users. Issues such as inflammation and changes to cellular structures in the lung have been observed, suggesting that more comprehensive studies are needed to understand long-term effects fully.
Why Consumers Choose E-Cigarettes
Many opt for vaping over smoking due to the perceived decrease in harm and the absence of the tar and many carcinogens found in combustible cigarettes. However, it is important to continue evaluating its role as a smoking cessation tool and its complete health profile.
