What schedule of controlled substances has low potential for abuse and is accepted medically?

The correct choice reflects that Schedule 4 substances have a low potential for abuse and are accepted for medical use. Schedule 4 includes medications that are deemed to have a lower risk of dependency compared to substances in schedules that indicate a higher potential for abuse. These substances typically require a prescription due to their regulated nature, but the risk associated with their use is relatively low when compared to substances in higher schedules.

This classification allows for the prescription of medications that can be beneficial for patients while also putting safeguards in place to prevent misuse. In contrast, substances in Schedule 1 are not accepted for medical use and have a high potential for abuse, while Schedule 3 and Schedule 5 substances have various degrees of acceptable medical uses but do not fit the criteria of having low potential for abuse as effectively as those in Schedule 4.
