22
Q
according to the disease theory, what do the genes or biochemical abnormalities that precede substance use do to precede substance use?

Q
what are the common approaches to disease theories in the community

12 step models, psychoanalytic view, personality theories, genes/genetics, endorphin deficiency theory
25
what does the 12 step model believe dependence is?
it is a spiritual disease and a lack of control
26
what are types of 12 step models?
AA, NA, Alcoholics-Anon
27
what are the main premises of the 12 step model
