Which controlled substances schedule typically includes substances with limited quantities of narcotics?

Schedule 5 substances typically include those that contain limited quantities of narcotics and are generally considered to have a lower potential for abuse relative to substances in higher schedules. This category is often defined by specific formulations that contain not more than a certain amount of narcotic drug per dosage unit or not more than a specified quantity per 100 milliliters. For instance, preparations that include cough preparations containing less than 200 mg of codeine per 100 milliliters may fall under this schedule.

In contrast, the other schedules contain substances that are associated with higher potential for abuse or more significant risks. Schedule 1 substances are considered to have no accepted medical use and a high potential for abuse. Schedule 3 includes substances that have accepted medical use but a moderate potential for abuse, while Schedule 4 substances feature drugs that have a lower potential for abuse compared to those in Schedule 3 but do not typically include specifically constrained formulations like those found in Schedule 5. Thus, Schedule 5 is the correct choice for substances with limited quantities of narcotics.
