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.
