Schedule 2 drugs are characterized by:

Schedule 2 drugs are classified as having a high potential for abuse, which may lead to severe psychological or physical dependence. This classification underscores the serious risks associated with these substances, such as opioids and certain stimulants, which are recognized for both their medicinal uses and the potential for misuse. The presence of severe dependence reinforces the necessity for stringent controls and regulations surrounding their prescription and distribution, highlighting that while they may be medically useful, their potential for addiction is significant.

The other options reflect characteristics associated with different schedules of controlled substances. For instance, drugs with little to no potential for abuse would fall under a lower schedule, while those with no accepted medical use would be categorized even higher (like Schedule 1). Additionally, drugs with a low risk of dependence typically belong to a different category altogether, indicating that Schedule 2 drugs are distinct in the level of risk they present.
