Which schedule represents substances that may lead to limited dependence and have accepted medical uses?

1. Schedule III

2. Schedule IV

3. Schedule V

4. Schedule I

The correct answer is: Schedule IV

The classification of controlled substances is based on their potential for abuse, accepted medical use, and the level of dependency they may cause. Substances categorized under Schedule IV are those that have a legitimate medical use and a low potential for abuse relative to substances in higher schedules. While there is still some risk of dependency, it is significantly limited compared to higher schedules. Schedule IV includes medications like certain anti-anxiety agents and muscle relaxants, which can be prescribed for legitimate medical needs. These drugs can have risks associated with misuse or addiction, but they are also deemed safe enough for medical application when used as directed. In contrast, the other schedules present substances with varying levels of potential for dependence and medical acceptance. Schedule III substances may lead to moderate dependence and have accepted medical uses, but they are generally considered to have a higher potential for abuse than Schedule IV. Schedule V medications have even lower abuse potential than Schedule IV but are not as commonly recognized in practice. Lastly, Schedule I substances are characterized by a high potential for abuse and no accepted medical use. Thus, Schedule IV is accurately represented as containing substances that may support limited dependence while having accepted medical uses.
