The most important thing a person with lung disease can do is STOP SMOKING. Smoking is the number one cause of COPD and can make any kind of lung disease worse. Medications are available that can help a person stop smoking (such as the "patch"). Sometimes even multiple medications may be needed. Eating a healthy diet, drinking plenty of water and juice, and taking vitamin supplements can make withdrawal easier and less uncomfortable.

People who smoke and have lung disease need extra support and encouragement from family members, friends, and caregivers so they can stop smoking. Professional counselors can also help. Activities should be planned that reduce depression and stress, which can make a person want to "light up."
