Answer to Question 1

Answer: Twin studies suggest the importance of both heredity as well as environment.
Specifically, abuse of every drug type (except for psychedelics) was influenced by genetics. Genetics seem to be important for determining whether a person becomes addicted. Heritability estimates range from 0.4 to 0.6.

Answer to Question 2

Answer: There is a comorbidity between schizophrenia and drug abuse. Half of all schizophrenia patients also suffer from drug or alcohol abuse or engage in smoking. Smokers with a psychiatric disorder constitute 7 of the general population but consume 34 of all cigarettes.
