A bill to amend the Controlled Substances Act to extend the limitations period for certain offenses resulting in death or serious bodily injury.

S. 4209 would amend the Controlled Substances Act to extend the statute of limitations for prosecuting certain drug offenses that cause death or serious bodily injury. Currently, there are time limits on how long federal prosecutors can bring charges for these crimes. This bill would allow prosecutors more time to investigate and file charges in cases involving drug-related deaths or serious injuries.

If enacted, this change could affect how federal law enforcement pursues drug-related cases, potentially allowing prosecutions to proceed even after longer delays. The bill is currently in the early stages of the legislative process, having been introduced in the Senate on March 25, 2026, and referred to committee for consideration. It has not yet been voted on by the full Senate.
