An electronic cigarette (e-cigarette), or vape,is a device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor,often called "vaping".
What is a vape pen?
The atomizer is a heating element that vaporizes a liquid solution called e-liquidthat cools into an aerosol of tiny droplets, vapor and air.The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on matters such as user behavior.E-cigarettes are activated by taking a puff or pressing a button.Some look like traditional cigarettes,and most kinds are reusable.
Is vaping harmful?
Vaping is less harmful than smoking,but still has health risks.Vaping affects asthmaand chronic obstructive pulmonary disease.Nicotine is highly addictive.Limited evidence indicates that e-cigarettes are less addictive than smoking, with slower nicotine absorption rates.
What other uses does it have?
E-cigarettes containing nicotine are more effective than nicotine replacement therapy (NRT) for smoking cessation,but have not been subject to the same rigorous testing that most nicotine replacement therapy products have.
An electronic cigarette consists of an atomizer, a power source such as a battery,and a container for e-liquid such as a cartridge or tank.
E-cigarettes have evolved over time, and the different designs are classified in generations. First-generation e-cigarettes tend to look like traditional cigarettes and are called "cigalikes".Second-generation devices are larger and look less like traditional cigarettes.Third-generation devices include mechanical mods and variable voltage devices. The fourth-generation includes sub-ohm tanks (meaning they have electrical resistance of less than 1 ohm) and temperature control.There are also pod mod devices that use protonated nicotine, rather than free-base nicotine found in earlier generations,providing higher nicotine yields.
