The definition of 'Controlled Substance' includes the aggregate weight of any mixture, solution, or other substance containing a controlled substance. True or false?

• A. True
• B. False
• C. Only if the mixture exceeds a threshold
• D. Not defined

Answer: (A)

The weight used to classify and charge a controlled substance includes the entire mixture or substance that contains the drug. In other words, the aggregate weight of the whole mixture, not just the pure amount of the controlled substance, determines the offense level. This reflects how penalties are set based on the total quantity someone possesses, including diluents or fillers. Therefore, the statement is true. It isn’t about a threshold or being undefined—the definition explicitly covers the aggregate weight of the mixture.
