Cannabis law in Utah (2026)

Last reviewed: 9 October 2026

In short: Possession of marijuana is a class B misdemeanour in Utah, rising for repeat convictions. Production and supply are offences. A medical cannabis programme lets qualified patients buy from licensed medical cannabis pharmacies on a provider's recommendation.

Notes

  • Penalties are one degree higher inside a correctional facility. The version of the section read took effect on 7 May 2025; the current-version link on the legislature site loads its text dynamically and could not be read.
  • Supply is lawful only as authorised under the medical cannabis provisions of Title 26B, Chapter 4, Part 2, through licensed medical cannabis pharmacies to cardholders.
