When must random drug tests begin?

• A. After completion
• B. Only with self-report
• C. Upon enrollment
• D. After 3 months

Answer: (C)

Random drug testing should start when a person enrolls in the program. Beginning at enrollment provides an initial baseline and keeps monitoring continuous from the very start, which helps detect relapse early and supports appropriate treatment decisions. Relying only on self-report is unreliable, and starting after completion or after a set delay (like three months) would miss early use and undermine accountability.
