  1. opium
  2. alcohol
  3. tobacco (chewing)
  4. cocaine

Solution

The chronic intake of alcohol may be fatal for the individual. On intake, a part of alcohol is changed to acetaldehyde which causes hangover. Acetaldehyde stimulates formation of fat which is deposited on artery walls (causing coronary ailments) and in the liver (causing fatty liver syndrome). Gradually, the liver hardens and dries up as its cells are replaced by fibrous tissue. This kind of liver degeneration is called liver cirrhosis (Laennec's cirrhosis). Excessive use of alcohol may also lead liver failure, liver cell carcinoma, etc.
