How does alcohol damage the liver? how is this similar to the damage nicotine causes the lungs?

Chronic alcohol abuse causes destruction of liver cells, which results in scarring of the liver (cirrhosis), alcoholic hepatitis and cellular mutation that may lead to liver cancer. Heavy drinking and smoking alone are of significant health hazard. The combination of the two, however, can result in synergistic adverse effects particularly in incidences of various cancers (e.g., esophagus).
