Which schedule of drugs is characterized by moderate or low physical dependence?

Schedule 3 drugs are characterized by having moderate or low physical dependence and a lower potential for abuse compared to those in Schedules 1 and 2. These drugs may still possess therapeutic benefits and are often used in clinical settings for various medical conditions. Examples include medications like anabolic steroids and some medications containing hydrocodone or codeine in lower dosages.

In contrast, Schedule 1 drugs are not accepted for medical use and have a high potential for abuse, resulting in severe physical and psychological dependence. Schedule 2 drugs have a high potential for abuse as well but are accepted for medical use with strict regulations to manage their use and distribution. Schedule 4 drugs have a lower potential for abuse than Schedule 3 drugs, leading to much less stringent controls. Therefore, Schedule 3 is the correct classification for drugs that warrant moderate or low physical dependence.
