What Is Smoking?
Smoking refers to the act of burning tobacco and inhaling its smoke. This smoke contains over 7,000 harmful chemicals, including tar, nicotine, formaldehyde, and arsenic. These toxic substances enter the lungs, bloodstream, and organs, leading to long-term damage.

Common Health Effects of Smoking:
- Lung cancer and chronic bronchitis
- Heart disease and stroke
- Reduced oxygen supply due to carbon monoxide
- Poor immune response and wound healing
What Is Vaping?
Vaping involves inhaling vaporized liquid using a battery-operated device such as a vape pen or pod system. The e-liquid contains nicotine, propylene glycol, glycerin, and flavorings. Vaping does not involve combustion, but the vapor still contains harmful chemicals.

Youth and Teen Concerns
Vaping vs smoking is a hot topic in schools and households, with youth vaping rapidly increasing. Teen brains are more vulnerable to nicotine, which affects memory, concentration, and learning ability. Flavored vapes attract young users and often lead to nicotine addiction.
In fact, studies from the CDC show that over 2 million U.S. middle and high school students reported current e-cigarette use in 2023.
Environmental Impact
- Cigarettes: The most littered item globally; they pollute soil and water and contain non-biodegradable filters.
- Vapes: Electronic waste from disposable devices, batteries, and plastic pods contributes to pollution.
