What is an Electronic Cigarette? The 2026 Breakdown

At its core, an electronic cigarette is a device that heats a liquid (known as e-liquid or vape juice) to create a vapour, which is then inhaled. It's designed to simulate the act of smoking but without the combustion—the burning of tobacco—which is responsible for producing the vast majority of harmful toxins in cigarette smoke.

Think of it like a tiny, personal kettle. Instead of boiling water to make steam for a cup of tea, it heats e-liquid to create a flavoured vapour containing nicotine. This process is called vaping.
