What is the common factor of all forms of drug abuse?

• A. Physiological Tolerance
• B. Psychological Dependence
• C. Genetic Susceptibility
• D. Environmental Influences

Answer: (B)

Psychological dependence is the common thread in all forms of drug abuse. It centers on craving and a mental preoccupation with using the drug, which creates a powerful urge to seek it out and continue taking it even when there are negative consequences. This urge can drive repeated use across different substances, making the behavior compulsive. Physiological tolerance and withdrawal can occur with many drugs, and genetic susceptibility or environmental influences can shape who is at risk, but they are not universal features of every case. The universal element is the psychological pull—the craving and need to use the drug that sustains the abuse pattern.
