What characteristics define Schedule I drugs?

Schedule I drugs are defined by their characteristics of having a high potential for abuse and no accepted medical use in treatment within the United States. This classification indicates that these substances pose significant risks, both in terms of addiction and potential for misuse, making them extremely regulated.

The absence of accepted medical use is critical to defining Schedule I substances. This means there is insufficient safety data for use under medical supervision, and as such, these drugs are prohibited for prescription by healthcare providers. Examples of Schedule I drugs include heroin and LSD. Overall, the focus on both the high potential for abuse and the lack of recognized medical use provides a clear framework for understanding the restrictions surrounding these substances.
