DVD LECTURE FOUR GENETICS—BORN TO BE AN ADDICT?
SUMMARY: GENETICS OF ADDICTION
• Nearly all aspects of addiction can be influenced by genetics

addictions • The existence of an “addictive personality” is
plausible • There is some progress toward establishing the
ways that specific genes affect addiction
