Shocking images show the tar blackened lungs of a 52-year-old man who had been a chain smoker for 30 years.
Viral video viewed more than 25 million times shows doctors removing the dead man's organs after their donation request.
But instead of being a healthy pink, they are heavily blackened by decades of accumulated tobacco waste.
The clip – called the "best anti-smoking ad" from all social media users – shows Dr. Chen Jingyu and his transplant team inspecting the lungs at Wuxi People's Hospital in Jiangsu, China.
Dr. Chen, who is one of the leading lung transplant surgeons and also vice president of the unit, said the donor was declared brain dead and his organs were donated.
However, the doctor quickly realized after the harvest that he would not be able to give a patient in need to the lungs on the waiting list, citing issues such as pulmonary calcification, bullous lung disease, and pulmonary emphysema – all thought of as a result. three decades of smoking.
Using the hashtag & # 39; jieyan & # 39; – Mandarin to stop smoking & # 39; – Dr. Chen wrote: “Many smokers in this country have lungs that look like this.
“Our team decided to reject these lungs for transplantation.
"If you smoke a lot, your lungs may not be accepted, even if you choose to donate them after death.
"Look at those lungs – do you still have the guts to smoke?"
Dr. Chen later told local media: "The patient did not undergo a CT scan before his death. He was declared brain dead and his lungs were donated shortly thereafter.
"The initial oxygenation tests were good, but when we harvested the organs, we realized we couldn't use them.
“We Chinese love to smoke. It would be impractical to say that we do not accept the lungs of all smokers, but there are strict standards.
“This includes lungs under 60 years old in a patient who was recently declared clinically dead; Minor lung infections and relatively clean chest X-rays are also acceptable.
"If the above conditions are met, we would consider lung transplantation."
According to a 2018 study by the China Center for Disease Control and Prevention, 26.6% of the country's population over 15 years old are smokers.
In 2017, the World Health Organization reported that worldwide tobacco use causes 7 million deaths per year.
