Which controlled substances schedule includes substances that contain limited quantities of certain narcotics with a low potential for abuse?

Schedule V includes controlled substances that contain limited quantities of certain narcotics and have a lower potential for abuse compared to substances in higher schedules. These may include medications that combine narcotics with non-narcotic ingredients, and they are commonly used for therapeutic purposes, such as cough preparations with codeine. The low potential for abuse associated with these substances allows them to be available with less stringent regulations compared to those in higher schedules, making them accessible for medical use while still being monitored for safety and misuse.

In contrast, Schedule II substances are highly regulated due to their significant potential for abuse, while Schedule III and Schedule IV substances have varying degrees of restrictions but are still higher in their potential for abuse than Schedule V. This distinct classification helps to ensure that medications are used appropriately and that potential for abuse is minimized.
