Which of the following is a feature of physical dependence in substance abusers?
A. Tolerance
B. Compulsive behavior
C. Withdrawal
D. A and C
ANS: D
Features of physical dependence, such as tolerance and withdrawal, can be normal responses to prescribed medications that affect the central nervous system and needs to be differentiated from addiction. Moreover, although marijuana abuse can be functionally very impairing, physical dependence is not part of the clinical picture. These mental and behavioral aspects are more specific to substance use disorders than the physical domains of tolerance and withdrawal, which are not unique to addiction (Stetka & Correll, 2013).
