How do e-cigarettes work, their benefits, and risks?

A majority of e-cigarettes contain:

  • A mouthpiece or a cartridge
  • A heating element
  • A rechargeable battery
  • Electronic circuits

When the user sucks on the mouthpiece, the heating element is activated by a sensor that further vaporizes the flavored liquid solution present in the mouthpiece.

  • The mouthpiece of an e-cig is fixed to the end of a tube. There is a small plastic cup present that holds an absorbent material. The mouthpiece or cartridge can easily be replaced or re-filled when required.
  • The liquid present in the mouthpiece is heated with the help of a heating element allowing the solution to be inhaled.
  • The heating element is powered with the help of a rechargeable lithium-ion battery.
  • As soon as the user sucks on the device, the sensor activates the heater. Often, an LED is present to show its activation.
  • The solution is also called e-liquid or e-juice. It is made by extracting nicotine from tobacco and then mixing it with a base.

Benefits of e-cigarettes

E-cigarettes are known to be way better than conventional smoking as they have fewer health risks. There are several studies that show e-cigarettes can help smokers quit smoking. While some studies suggest that they have modest benefits when it comes to quitting, they definitely have great potential in cutting down smoking.

Hence, it can be concluded that e-cigarettes can benefit adult smokers as long as they are not pregnant and who have completely replaced any other tobacco or nicotine products.

It is believed that instead of smoking, vaping is a better option for young people. However, one should not forget that vaping is not completely risk-free.


While e-cigarettes are known to help people quit smoking, there is growing evidence that vaping may have some harmful health risks.

  • There are some e-cigarettes that contain nicotine, which harms the adolescent brain. Moreover, it is hazardous during pregnancy and can have a negative impact on fetal development.
  • Aerosol contains solvents, flavorings, and toxicants that are potentially harmful.
  • Your lungs are exposed to different substances which can cause severe lung disease.
  • Accidently swallowing and inhaling e-liquid can cause fatal poisoning.
  • People who switch to e-cigarettes to quit smoking will eventually stop using conventional and medically monitored ways of doing so.
  • Those who are addicted to vaping may never quit smoking altogether.
  • Young people who vape are likely to try tobacco as well.
  • Regular use of nicotine can make other drugs such as cocaine more attractive and pleasurable.
  • The concept that vaping is not harmful and the temptation of flavoring can tempt teenagers to start vaping. This may increase the chance that they will smoke conventional cigarettes later.
  • Vaping releases carcinogenic emissions.
