Disposable e-cigarettes are e-cigarettes that do not require charging or cartridge replacement; they are used once and then discarded.
Disposable e-cigarettes have a one-piece structure, with the battery and atomizer inseparable. The atomizer cannot be refilled, and the battery cannot be recharged. The number of puffs depends on the battery capacity and e-liquid volume. They employ a completely sealed design, eliminating the need for charging and cartridge replacement. Most use a pneumatic switch for activation, making them simple to use, portable, and requiring no charging, cartridge replacement, or heavy chargers or other accessories. They offer a variety of flavors and attractive designs.
E-liquids contain harmful substances such as formaldehyde and acetaldehyde, and the aerosol also contains toxic substances. Heavy metals such as tin, copper, nickel, and arsenic can be detected in the aerosol. The accumulation of heavy metals in the body can damage health, especially the nervous system. The state explicitly prohibits the sale of flavored e-cigarettes other than tobacco flavors. The illegal production and sale of fruit-flavored e-cigarettes requires increased enforcement to build a "firewall" for public safety.
