Phenobarbital is an example of substances in Penalty Group 3 (PG3). Which group does Phenobarbital belong to?

• A. PG3
• B. PG1A
• C. PG1B
• D. PG4

Answer: (A)

Phenobarbital belongs to Penalty Group 3 because it is a barbiturate with legitimate medical uses but has a clear potential for abuse and dependence. The penalty groups organize controlled substances by how widely they’re regulated, balancing medical utility with risk of harm. Barbiturates like phenobarbital sit in PG3 as a middle tier of control, reflecting their medical value while acknowledging their abuse potential. This means possession or distribution carries penalties appropriate to PG3 substances. Other groups cover substances with different risk and use profiles, so phenobarbital would not be placed in those other groups.
