Hookah pens, also known as electronic hookahs, e-hookahs, or shisha pens, are devices that simulate the experience of smoking hookah without the use of tobacco. They typically consist of a battery-powered heating element and a replaceable cartridge filled with a liquid that contains flavorings, vegetable glycerin, propylene glycol, and sometimes nicotine.
Users inhale the vapor produced by the heating element through a mouthpiece, which is similar to smoking a traditional hookah. The liquid in the cartridge is heated and vaporized, creating a smoke-like substance that is then inhaled.
Hookah pens have become popular among young people as an alternative to smoking traditional cigarettes and hookahs. However, it is important to note that while they may be marketed as a safer alternative, they still contain nicotine and other potentially harmful chemicals, and their long-term effects on health are not yet fully understood.
