Schedule III substances are classified as having the potential to lead to moderate or low physical dependence and high psychological dependence. This schedule includes drugs that do not meet the criteria for the higher schedules but still have a recognized potential for abuse.
Drugs under Schedule III may include certain anabolic steroids, ketamine, and some medications containing lower amounts of codeine, which can lead to dependence if misused. The regulation around Schedule III reflects the necessary oversight for substances that are less harmful compared to Schedule I and II drugs, which are associated with greater risks of severe dependence and less accepted medical uses.
In contrast, substances in Schedule I are considered to have no accepted medical use and a high potential for abuse, while Schedule II drugs, such as opioids and stimulants, are recognized for their medical uses but have a high potential for severe dependence. Schedule IV substances are considered to have a lower potential for abuse and may lead to limited dependence compared to those in Schedule III. This framework helps in ensuring that substances that pose a potential risk for dependence are appropriately managed and monitored.
