75. Which of the following is a Schedule III controlled substance?

Answer: A

Explanation:

Codeine with acetaminophen is a Schedule III controlled substance.

Codeine with acetaminophen is classified as a Schedule III controlled substance due to its moderate potential for abuse and the presence of acetaminophen which mitigates some of the risks associated with pure opioids.

A) Codeine with acetaminophen

This option is correct as codeine combined with acetaminophen is categorized as a Schedule III controlled substance under the Controlled Substances Act. This classification reflects its recognized medical use along with a lower potential for dependence compared to substances classified in higher schedules.

B) Morphine

Morphine is classified as a Schedule II controlled substance. It has a high potential for abuse, leading to severe psychological or physical dependence, which is why it is not classified as Schedule III but rather has more stringent regulations.

C) Oxycodone

Oxycodone is also classified as a Schedule II controlled substance. Similar to morphine, it has a high potential for abuse and can lead to significant dependence, thus placing it in a stricter regulatory category than Schedule III.

D) Fentanyl

Fentanyl is classified as a Schedule II controlled substance as well. It is a potent opioid with a high potential for abuse and significant risk of overdose, warranting its placement in a higher schedule than Schedule III.

Conclusion

The classification of codeine with acetaminophen as a Schedule III controlled substance is primarily due to its dual composition, which reduces the risk of abuse compared to stronger opioids like morphine, oxycodone, and fentanyl, all of which are classified as Schedule II. This distinction is crucial in understanding the regulatory framework surrounding controlled substances and their medical usage.
