Which of the following is an example of substances in Penalty Group 1 (PG1)?

• A. Methamphetamine, cocaine, heroin, codeine, morphine, opium
• B. MDMA
• C. Synthetic marijuana
• D. Amphetamines

Answer: (A)

Penalty Group 1 includes the most dangerous and addictive drugs, those that carry the harshest penalties. The combination named here—methamphetamine, cocaine, heroin, morphine, codeine, and opium—are classic examples of substances classified in PG1. MDMA is typically placed in a different group (often PG2), while synthetic marijuana and the broad class of amphetamines are not listed as PG1. So this set fits PG1 because it contains the well-known PG1 drugs, the ones lawmakers target with the toughest penalties.
