At various times, drug dependence has been considered a(n) __________.

• A. Illness
• B. Moral violation
• C. Very bad habit
• D. All of the above

Answer: (D)

Drug dependence has been understood in several ways across history. Some thinkers have treated it as an illness, focusing on physiological and psychological processes and favoring medical treatment and public health approaches. Others have framed it as a moral violation, reflecting beliefs about personal responsibility and ethics, which often led to stigma and punishment. It has also been described as a very bad habit, emphasizing learned behaviors and environmental cues that can be changed with practice and habit formation. Because all three viewpoints have appeared in different times and settings, the most accurate choice is the one that includes illness, moral violation, and bad habit.
