Vapers are being warned about a new kind of harmful lung illness caused by using e-cigarettes which is being referred to as EVALI.
That stands for 'e-cigarette or vaping product use associated lung injury', which is a bit of a mouthful so EVALI it is, and unfortunately for vapers there are multiple recorded instances of it killing people.
Inflamed lungs can lead to a person wheezing and struggling to breathe and the studies demonstrate that vaping is harmful to you.
With that in mind Yale Medicine says that lung illness EVALI has a link with vitamin E acetate, which is found in some THC vaping products, and when inhaled this causes lung damage.
The symptoms of EVALI include being short of breath, coughing, suffering from chest pains, rapid and shallow breathing, an increased heart rate, fevers and chills, diarrhoea, nausea, vomiting and abdominal pain.
It's not a merry list at all, and many people diagnosed with EVALI require hospital treatment where they can have quick access to respiratory support and be closely monitored.
According to ABC, autopsy reports of people who have died from EVALI have found their lungs to be 'red, airless and very heavy, with a weight more than double what was expected'.
Because the lung illness is relatively new, the long-term health complications from EVALI are still unclear, with plenty of studies into the harmful effects vaping has on the body still being undertaken.
There has also not yet been enough time to collect proper data on whether a person's lungs can make a full recovery given enough time.
