Who is responsible for scheduling drugs at the federal level?

The responsibility for scheduling drugs at the federal level lies with the Attorney General. The Attorney General oversees the Drug Enforcement Administration (DEA), which is the agency that enforces the Controlled Substances Act. However, the Attorney General does not act alone; they consider the recommendations from various sources, including the Secretary of Health and Human Services and the National Institute on Drug Abuse.

When a substance is proposed for scheduling, the DEA may conduct an evaluation and then submit a recommendation to the Attorney General. Ultimately, it is the Attorney General who makes the final decisions regarding the scheduling of substances based on the law and the evidence presented.

In summary, while multiple parties may be involved in the process, the Attorney General is ultimately responsible for determining the scheduling of drugs under federal law, making this the correct answer.
