Controlled Substances Act Clarification in Sciences Act of 2026

This bill clarifies how drugs are defined and scheduled under the Controlled Substances Act to better balance public safety with medical access. It updates legal definitions for terms like "accepted medical use," "dependence," and "abuse" to include scientific research and evidence-based evaluations from state medical regulators. Additionally, it requires the Attorney General to defer to the Secretary of Health and Human Services on scientific assessments and to consider a drug's potential benefits to society when deciding on its schedule. These changes directly affect how the federal government classifies substances and aims to ensure that scheduling decisions are based on rigorous science rather than solely on the potential for abuse.
