To provide for a limitation on availability of funds for Department of Health and Human Services, National Institutes of Health National Institute on Drug Abuse for fiscal year 2024.

HR 1990 sets a maximum funding limit of $1.42 billion for the National Institute on Drug Abuse (NIDA) within the National Institutes of Health (NIH) for fiscal year 2024. This bill directly restricts the budget available to NIDA for drug abuse research and related programs during FY2024. The provision explicitly prohibits NIDA from accessing funds exceeding this specified amount, regardless of other funding authorizations. This is a procedural budget constraint, not a substantive policy change to drug abuse treatment or research.
