What is a characteristic of drugs listed under Schedule I?

Drugs classified under Schedule I are characterized by having no currently accepted medical use in the United States. This classification signifies that these substances are deemed to have a high potential for abuse, and their use is strictly limited within the medical community due to the risks involved.

While some drugs may lead to psychological dependence or may be recognized for their potential harmful effects, the defining characteristic of Schedule I substances is the absence of safe, recognized medical applications. This sets them apart from drugs in lower schedules, which may have accepted medical uses. Therefore, recognizing the lack of safe, accepted medical use is essential in understanding the implications of Schedule I drugs in terms of legality and medical treatment options.
