Signs & Symptoms of Popcorn Lung

Do you or someone you know still eat microwave popcorn? If you do, listen up. I cannot tell you how many times I have bought those boxes with tiny bags in them of delicious popcorn for movie night with my kids. Pop one in the microwave and the entire house smells all buttery and rich. My kids loved it. So did we. Until I learned about something called Diacetyl and something called popcorn lung.

What is Popcorn Lung?

Popcorn lung is a medical form of “bronchiolitis obliterans”, which prevents your lungs from functioning properly and is considered to be a life-threatening condition. It is caused by the inhalation of diacetyl, a chemical compound that is yellow or green liquid with an intensely buttery flavor used in the production of microwave popcorn, and it is known to cause damage to the lining of the respiratory tract. Over time the damage to the airway can cause permanent lung damage, which can and will become eventually fatal.

What are the Signs and Symptoms of Popcorn Lung? Can It Be Treated?

Popcorn lung is nothing to joke around about and has several signs and symptoms for you to be aware of. Most of these mimic other colds or symptoms of bronchitis and can include:

  • Shortness of breath
  • Coughing
  • Fever
  • Night Sweats
  • Weight loss

While there is no treatment or cure for popcorn lung and it is considered life altering. There are existing methods to help manage the symptoms, to make those living with popcorn lung more comfortable. However, in the end, it is extremely fatal. Some individuals have seen a successful reduction in the progress of the disease, but none of these methods have been proven to be reliable sources of treatment.

The Truth About Vaping and Popcorn Lung

Panic ensued among those in the vaping community after some noticed that diacetyl was being used in selective e-juice flavoring, and in turn, this caused a myth about vaping and popcorn lung. Cigarettes contain 100 times more diacetyl per cigarette than e-juice in Canada. And although many diseases and health issues have been linked to smoking combustible cigarettes, there has been no link to popcorn lung. No vaper has ever been diagnosed with popcorn lung, showing the magnitude of this myth and how damaging it can be to the community. Especially for people like my mother. 

My mom was diagnosed with chronic lung and heart disease. She turned to vaping after she had open heart surgery to help her quit smoking after 45 years of consuming cigarettes. She has not touched a cigarette in over four years and even her heart specialist contributes vaping to prolonging her life and increasing her health. With countless myths about vaping pens, the one with diacetyl linked to e-juice has to be the most damaging, due to the fear it instills in individuals who don’t know much about vaping or are considering making the switch from smoking to vaping, a decision which could potentially save their lives.


Very few, if any, e-juice manufacturers in Canada use diacetyl as an ingredient in their flavoring, due to the stigma and health concerns associated with it. Of course, we don’t want to be inhaling diacetyl. So if you have made the shift from smoking to vaping pens, remember that you were inhaling 100 times as much diacetyl smoking, along with 4000 other chemicals. Public health in England has done extensive studies on the health and safety of vape pens, as well as the effects of ingredients in e-juice flavors. It’s been concluded that vaping is still 95% safer for you than cigarettes are, making vaping a much healthier alternative to consider.

In Canada, e-juice is highly monitored, and the production and manufacturing of these products are regulated to ensure the safety of individuals. You can rest assured that e-juice in Canada is produced in an ISO 7 Standard Certified Lab with the cleanest facilities, as well as regulated procedures guaranteed to be consistent and safe for the vaping juices we buy.

In short, you have no need for concern, if you are choosing e-juice in Canada. Do your research and make sure what you are purchasing your e-juice from a reputable brand that cares about their customers. For more information on vaping in Canada, please visit
