Shocking pictures show tar-black lungs of a 52-year-old man who has been a chain smoker for 30 years.
The viral video that has been viewed more than 25 million times shows medications removing the organs of the brain dead man at his request to donate them.
But instead of being a healthy pink color, they are heavily blackened from decades of tobacco residue accumulation.
The clip – called the & # 39; best anti-smoking ad ever & # 39; of 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 a leading lung transplant surgeon and also vice president of the facility, said the donor was declared brain dead and his organs were donated.
However, the doctor quickly realized after harvest that they could not provide the lungs to a patient in need on the waiting list, citing problems such as lung calcification, bullous lung disease and pulmonary emphysema – all believed to be the result of three decades of smoking.
Using the hash tag & # 39; jieyan & # 39; – Mandarin for & # 39; quit smoking & # 39; – wrote Dr. Chen: "Many smokers in this country have lungs that look like this.
“Our team decided to reject these lungs for transplantation.
“If you are a heavy smoker, your lungs may not be accepted even if you choose to donate them after death.
"Look at those lungs – do you still have the courage 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 first oxygenation indexes were OK, 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 would not accept the lungs of all smokers, but there are strict standards.
These include lungs under 60 in a patient who has recently been declared medically dead; minor infections of the lungs and relatively pure chest x-rays are also acceptable.
"If the above conditions are met, we would consider transplanting the lungs."
According to a study from China's Center for Disease Control and Prevention in 2018, 26.6 percent of the country's population over 15 years are smokers.
In 2017, the World Health Organization reported that tobacco use in the world causes 7 million deaths per year.
