Which of the following is a valid PG2 substance example?

• A. MDMA
• B. Synthetic marijuana
• C. Cocaine
• D. Opium

Answer: (A)

PG2 substances are a category of controlled drugs that includes certain synthetic psychoactive substances. MDMA is a classic example because it is man-made, has stimulant and entactogenic effects, and is regulated as a prohibited substance in many jurisdictions. This synthetic, psychoactive profile places it in PG2, distinguishing it from drugs that are natural (like opium from the poppy plant) or from other synthetic drugs that belong to different categories or schedules. Synthetic marijuana, while also synthetic, is typically treated under its own category due to the variety of compounds involved, and cocaine and opium are usually categorized differently because they’re traditional, plant-derived drugs.
