Tobacco addiction is caused by a dependence on nicotine, report doctors at the Mayo Clinic. Cigars, pipes and cigarettes all can create an addiction to nicotine, which also is present in smokeless tobacco products. A person is addicted to tobacco when he can't stop using a product despite harmful consequences and sometimes even with a strong desire to stop.
Features
Nicotine affects the brain by producing pleasurable and mood-altering effects that become addictive, spurring continued use of the product.
Withdrawal
Addiction is present when a person experiences withdrawal symptoms when she doesn't use a tobacco product. Nicotine withdrawal symptoms include irritability and anxiety.
Effects
Tobacco addiction can cause cosmetic effects such as yellow teeth and fingers, and sagging wrinkled skin. Smokers are more susceptible to flu and cold viruses and other diseases such as diabetes and osteoporosis.
Warning
Tobacco addiction can lead to serious health problems, including stroke, heart disease, chronic respiratory problems and cancer. The National Institute on Drug Abuse reports that tobacco kills nearly half a million people every year.
Considerations
Young people who begin using tobacco products face a greater chance of developing a long-term addiction. Mayo Clinic doctors report that heredity also plays a role in tobacco addiction.
Treatment
Counseling and medication can help tobacco addicts quit. Nicotine replacement therapy in the form of gum, a patch or inhaler can ease the withdrawal pains of quitting.
