Which stage is not a stage in the development of cocaine addiction?

• A. Isolated Use
• B. Experimentation
• C. Regular Use
• D. Chronic Dependence

Answer: (A)

The concept being tested is how cocaine use typically progresses toward addiction. In most clinical models, progression moves from trying the drug (experimentation) to using it in a regular pattern (regular use) to reaching a dependent, addicted state (chronic dependence). Isolated use does not represent a stage in this developmental sequence; it’s usually a one-time or infrequent event and doesn’t show the increasing involvement that characterizes the progression toward addiction. That’s why this option is the best answer—it doesn’t describe a phase in the trajectory toward cocaine addiction. The other stages fit the pattern: experimentation marks initial exposure, regular use indicates a patterned, ongoing use, and chronic dependence reflects addiction with tolerance, withdrawal, and compulsive use.
