Electric vape

E-cigarettes (Electric Vape) are electronic devices that are powered by batteries and heat liquid to produce aerosol (commonly known as "steam") for inhalation by users. They are fundamentally different from traditional cigarettes, which produce smoke through the combustion of tobacco.
⚙️ Core Components and Working Principle
All electronic cigarette devices are composed of three core components:
Battery: Provides electricity.
Atomizer: It contains a heating coil, which is responsible for heating the e-liquid for atomization.
Cartridge/Pod/Tank: Used for storing e-liquid.
When the user inhales, the battery powers the heating atomizer, which heats the e-liquid in the oil reservoir into aerosol, which is then inhaled into the lungs. The main components of the e-liquid usually include propylene glycol and vegetable glycerin as the base liquid, nicotine (with concentrations ranging from 0 to over 50 milligrams per milliliter), and various flavoring agents.
Main types
E-cigarettes come in various forms and can be mainly classified into the following categories:
Disposable electronic cigarettes: Discarded after use, no need for charging or refilling with oil. Brands such as "Puff Bar" are examples.
Rechargeable electronic cigarettes (Pod Systems): Compact and portable, they typically use sealed cartridges pre-filled with e-liquid, and are currently the mainstream products on the market.
Oil-filled electronic cigarettes (Tank Systems / Mods): Larger in size, allowing users to add their own e-liquid, highly playable, and producing a large amount of smoke.
Heated non-combustible products (Heated Tobacco Products): Such as IQOS, which precisely heats the tobacco rather than burning it, releasing nicotine and aroma.
Major Brands and Markets
The global e-cigarette market is projected to exceed 60 billion US dollars by 2025. Approximately 70% of the production capacity is concentrated in Shenzhen, China.
Global market: The major brands include JUUL Labs from the United States, Vuse, as well as RELX from China and SMOORE from China. The leading brands in the global market share are "Elf Bar" of Eleaf (6.0%), "Lost Mary" (2.4%), and RELX (1.7%).
Chinese market: Yuleke (RELX) holds an absolute dominant position, with a market share exceeding 60%. Other well-known brands include FLOW, MOTI, YOOZ, and BOLERO, etc.
⚠️ Health Risks and Misconceptions
Although e-cigarettes are often promoted as a "safe alternative" to traditional cigarettes or a "smoking cessation tool", scientific evidence has revealed their serious health risks:
Not harmless: The aerosol from electronic cigarettes contains carcinogens such as formaldehyde and acetaldehyde, as well as heavy metals like nickel, tin, and lead. These substances have clear negative impacts on human health.
Highly addictive: The vast majority of e-cigarettes contain nicotine and are highly addictive.
The effectiveness of quitting smoking is questionable: Research shows that e-cigarettes do not effectively increase the rate of quitting smoking. Instead, they may lead to dual use (simultaneously smoking traditional cigarettes and e-cigarettes), and their health risks are higher than those of pure smokers.
It can cause various diseases: Using electronic cigarettes is associated with an increased risk of cardiovascular diseases (such as high blood pressure, heart attack), chronic respiratory diseases (such as COPD), and cancer.
Teenage Risks: E-cigarettes are becoming popular among teenagers, not only causing nicotine addiction but also increasing their likelihood of smoking traditional cigarettes in the future. It is estimated that 15 million teenagers aged 13 to 15 worldwide use e-cigarettes.

?? Summary
E-cigarettes are electronic devices that generate aerosol by heating e-liquid. They are not harmless "water vapor". They also contain nicotine, carcinogens and heavy metals, posing clear risks to health, especially to the cardiovascular and respiratory systems, and are not conducive to quitting smoking.
