How does biology relate to addiction?
Biological models of addiction emphasize the importance of genetics and the biological forces of nature. These theories suggest that brain chemistry, brain structure, and genetic abnormalities cause human behavior.
Are there genetic influences on addiction?

What gene is responsible for addiction?
Researchers demonstrated that a type of small infectious agent (a type of RNA virus called human endogenous retrovirus-K HML-2, or HK2) integrates within a gene that regulates activity of dopamine. This integration is more frequently found in people with substance use disorders, and is associated with drug addiction.
Is addiction hereditary or environmental?
Addictions are moderately to highly heritable. Family, adoption, and twin studies reveal that an individual’s risk tends to be proportional to the degree of genetic relationship to an addicted relative. Heritabilities of addictive disorders range from 0.39 for hallucinogens to 0.72 for cocaine3 (Figure 1).
How does genetics affect alcoholism?
Those who have a family history of alcoholism have a higher risk of developing a drinking problem. Studies show that alcoholism is approximately 50% attributable to genetics.
What are the biological effects of drugs?

What brain chemicals are involved in addiction?
