E-cigarettes, or vapes, are devices that heat a liquid (e-liquid) to produce inhalable aerosol. The liquid typically contains nicotine, propylene glycol, vegetable glycerin, and flavorings. Unlike traditional cigarettes, e-cigarettes operate without combustion, reducing exposure to harmful substances like tar and carbon monoxide. This has positioned them as a potential harm reduction alternative for smokers.

Key Advantages:

Adjustable nicotine levels (including nicotine-free options).

Wide variety of flavors and compact, portable designs.

Potential Risks:

Aerosol may contain toxic byproducts (e.g., formaldehyde) under high-heat conditions.

Long-term inhalation could contribute to lung inflammation.

Nicotine addiction risks, particularly for non-smokers and youth.

Growing teen vaping rates have raised public health alarms, prompting stricter global regulations on advertising and underage sales. Consumers should prioritize certified products and make informed decisions by weighing the pros and cons. While e-cigarettes may support smoking cessation when used strategically, they are not risk-free. Caution and moderation remain essential for safe usage.
