HB 173 Utah House · 2025 General Session

Controlled Substances Act Amendments

HB 173 adds tianeptine and phenibut to Utah’s Schedule I controlled substances list, making them illegal to possess or distribute without authorization. This directly affects individuals who use or distribute these substances in Utah, as they will now face the same legal restrictions as other Schedule I drugs like fentanyl derivatives. The bill updates Utah’s Controlled Substances Act to include these specific chemicals, aligning with federal classifications but not changing existing medical use exceptions. No new funding or administrative requirements are introduced.
