In the simplest terms, cigarettes burn tobacco to release nicotine and flavor while e-cigarettes heat a liquid to produce a vapor.
What are e-cigarettes?
There are three types of devices. The earliest, cig-a-likes, resemble real cigarettes, the ends usually light up. Vape pens look like long pens and come in a range of styles; while advanced personal vaporizers, or “vape mods,” are bigger devices that you can modify, e.g. by adding a larger liquid chamber.
How do they work?
Broadly speaking, all three types include a rechargeable battery and a heating element. A disposable cartridge is then inserted that holds the e-liquid, which produces the vapor that’s inhaled. These liquids come in many flavors. The vast majority of liquids—and their vapors—include nicotine.
Heated tobacco devices are based on the concept of heating tobacco to temperatures well below those reached by a burning cigarette. This releases a vapor containing nicotine and flavors.
What is heated tobacco?
It’s proper tobacco, but it is processed in a different way because it needs to be uniformly heated to work correctly. Products that heat rather than burn tobacco first appeared in the ’90s. However, a new generation of research-led products has now been developed. By heating the tobacco they still produce nicotine and tobacco flavor but with much lower levels of harmful or potentially harmful chemicals.
How does it work?
A tobacco stick is usually inserted into a hollow, electronic device. The device has its own battery, which heats the tobacco until it releases the vapor. This vapor is then inhaled. Once used, the stick is discarded, and the device recharged.
