Do you think that nonsubstance-related addictions, such as compulsive gambling or compulsive eating, have a greater
genetic or environmental component compared to substance-related additions, such as nicotine? Explain your reasoning. What will be an ideal response?
ANSWER: Answers will vary.
Background:Addictions
develop from a stepwise series of physiological adaptations that alter brain
function following repeated exposure to certain environmental stimuli. As with other
behavioral disorders, family studies (pedigree analysis), twin studies, and adoption studies
have concluded that many different types of addiction have genetic components.
