- Withdrawal symptoms can occur in individuals who have become addicted to alcohol and try to give it up; symptoms include headaches, depression and body tremors
- Long-term effects of alcohol abuse have been linked to
- liver disease such as cirrhosis of the liver due to toxic waste products from the breakdown of alcohol in the liver; the liver is the primary site for drug metabolism
- cancers such as mouth cancer as toxic products can damage DNA and cause cancerous cell mutations
- circulatory and heart diseases as alcohol increases blood pressure
