What type of drugs may lead to moderate or low physical dependence as classified under Schedule III?

The classification of drugs under Schedule III is based on their potential for abuse and the degree of physical or psychological dependence they may cause. Schedule III drugs are recognized as having a moderate to low potential for physical and psychological dependence. The key characteristic of these substances is that they also possess well-documented medical uses, which distinguishes them from drugs classified in higher schedules with more restrictive regulations.

Drugs in this category may include certain anabolic steroids, ketamine, and specific barbiturates, which are utilized for various therapeutic purposes while maintaining a moderate risk for dependence compared to substances classified in Schedules I or II. This classification reflects a balance between ensuring accessibility for legitimate medical uses and recognizing the potential for abuse and dependence. Thus, the correct answer emphasizes the importance of medical application while acknowledging a controlled risk of dependence, aligning perfectly with the criteria for Schedule III substances.
