What is well-known is that Winehouse has a long history of drug abuse, including crack cocaine.
According to Horovitz, smoking crack can also result in a condition known as "acute crack lung," which shows up from one hour to 48 hours after smoking large quantities of crack. "It's temporary, but it can cause a certain amount of destruction of the lung tissue. But if you have enough [episodes], it adds up to a lot of lung disease," Horovitz explained.

Emphysema involves damage to the air sacs or alveoli in the lungs, reducing the amount of oxygen the body can take in. Symptoms typically include shortness of breath and a chronic cough, according to the U.S. National Institutes of Health. The most common cause is smoking. The disease, once entrenched, cannot be reversed. The condition can be stabilized, however, if a person stops smoking.
Still, "lung units or alveoli do not come back," Horovitz said.
Symptoms can be treated with bronchodilators, steroids, inhalers and, in a worst-case scenario, oxygen, Horovitz added.
According to AP, Winehouse's lung capacity is at 70 percent. Physicians generally conduct pulmonary function tests by taking into account height, weight, ethnic group and smoking history. They then calculate a predicted lung function.
Healthy lung function for a person with Winehouse's demographic would probably hover around 80 percent or more, Horovitz said.
"This is not moderate or severe emphysema. It's mild emphysema," Horovitz stressed. "But with the natural aging process, when you're 54, you're going to have moderate to severe emphysema."
The singer's career and young life have been marked by both highs and lows. Her 2006 album, Back to Black won five Grammy awards, including Best New Artist, Record of the Year and Song of the Year. But her alcohol and drug dependencies have been widely reported.
According to MTV News, Mitch Winehouse told the BBC that she is currently "smothered" in nicotine patches to help her kick the smoking habit.
Winehouse understands that "the only thing that can go into her lungs right now is fresh air," her father said. "She doesn't have emphysema, she has traces of it. Obviously, if she doesn't quit smoking, it's going to get worse."
