Vaping leads to popcorn lung

E-cigarettes have become common among those who are willing to quit smoking. Vaping has proved to be comparatively very less harmful to the health than the conventional smoking. The liquid used in the e-cigarette is made up of nicotine, propylene glycol, vegetable glycerin and flavorings.

The health risks of vaping are uncertain. Researchers have found that inhaling different flavors of e-cigarettes can cause great harm to human lungs and end up to popcorn lung. The stats, symptoms and causes of prolonged vaping are explained as below;


Stats on vaping among teenagers:

  • As per a survey conducted in 2015, the usage of e-cigars among the 8th grade children was around 9.5%.
  • Around 30.7% percent of children who used e-cigars diverted to conventional smoking within 6 months.
  • Thus, e-cigars rather than becoming an anti smoking agent, is now used as a kick start to smoking habits among teenagers.
  • After trying e-cigars these children divert towards conventional cigarettes, cigars or hookahs.
  • It’s studied that around 13.7% of teens are not aware of what is exactly present in their e-liquids. This is because the manufacturers don’t have to report about the ingredients used in their flavorings.


Symptoms of popcorn lung:

  • Wheezing that is related to bronchitis or asthma is a common symptom seen.
  • The constant dry cough is noticed.
  • Difficulty in deep breathing, especially during physical activities is experienced.
  • Exhaustion and tiredness.
  • Rapid breathing is experienced.
  • Constant skin, eye, mouth, or nose irritation is found.


Vaping - a cause of popcorn lung:

  • According to American Lung Association, e-cigs or vaping, especially the candy and fruit flavored one’s can cause popcorn lung.
  • The flavoring agents present in some e-liquid can cause conditions like bronchiolitis obliterans; this is commonly known as popcorn lung.
  • The chemicals diacetyl and acetyl propionyl are responsible for popcorn lung.
  • The researchers of Harvard found that out of 51 e-cigarette brands, 39 of them contained diacetyl.
  • It was also found that pentanedione and acetoin were also present in 23 and 46 brands out of 51 flavors tested.
  • Studies found that the workers in the flavoring factories who were exposed to these chemicals for a long time were reported with popcorn lung.


Hence, from the above, we understand that e-cigs, though considered a safe substitute for smoking, still have some disadvantages. Vaping should be done within limits and a detailed knowledge about the ingredients in the flavors should be known.
