The Short Answer: Medical Only, No Decrim
Utah’s cannabis law sits in two places. Recreational cannabis is fully illegal under the Utah Controlled Substances Act at Utah Code §58-37-1 et seq., with marijuana and tetrahydrocannabinols placed on Schedule I via §58-37-4(2)(a)(iii)(S) and (AA). Medical cannabis is carved out separately by the Utah Medical Cannabis Act at §26B-4-201 et seq. (recodified from the original §26-61a in 2023). Concentrates and hashish are folded into the marijuana definition at §58-37-2(1)(s) — meaning a gram of wax is treated identically to a gram of flower for charging purposes.
As of March 31, 2026, 112,093 active patients hold Utah medical cannabis cards — roughly one in every 30 Utahns. Yet possession of a single joint by a non-cardholder remains a Class B misdemeanor punishable by six months in jail. This contradiction is the engineered outcome of the 2018 Utah Compromise.
Marijuana is classified as a Schedule I controlled substance under §58-37-4(2)(a)(iii)(S). The Utah Medical Cannabis Act at §26B-4-201 carves out lawful medical use for registered cardholders.

Possession Penalties at a Glance
The 2015 Justice Reinvestment Initiative (HB 348) collapsed the old weight tiers. Today, under §58-37-8(2)(d), possession of any amount under 100 pounds is treated identically — the previous weight ladder was eliminated. (Note: a widespread claim that HB 348 made small-quantity possession an “infraction” is incorrect. Possession remains criminal misdemeanor.)
| Offense | Class | Maximum Sentence |
|---|---|---|
| Possession < 100 lb (1st or 2nd offense) | Class B misdemeanor | 6 months jail, $1,000 fine |
| Possession (3rd offense) | Class A misdemeanor | 364 days jail, $2,500 fine |
| Possession (4th+ within 7 years) | 3rd-degree felony | 5 years prison, $5,000 fine |
| Possession 100 lb+ | 2nd-degree felony | 1–15 years prison, $10,000 fine |
| Cultivation / distribution / PWISD (1st) | 3rd-degree felony | 5 years, $5,000 |
| Continuing criminal enterprise | 1st-degree felony | 5 years to life |

Paraphernalia: A Separate Statute
Paraphernalia is governed by the separate Utah Drug Paraphernalia Act, §58-37a. Possession or use under §58-37a-5(1) is a Class B misdemeanor; delivery or manufacture-with-intent-to-deliver under §58-37a-5(2) is a Class A; delivery to a minor under §58-37a-5(3) by a person 18+ who is at least three years older than the recipient is a third-degree felony. A 2024 amendment carved out fentanyl test strips and other testing equipment from the paraphernalia definition — a small but meaningful harm-reduction win. See paraphernalia for the full breakdown.
The .05 BAC Standard
Utah’s DUI statute is Utah Code §41-6a-502. The .05 BAC threshold, lowered by HB 155 (2017) effective December 30, 2018, is the strictest in the nation — Utah is the only U.S. state at .05 as of April 2026. Cannabis-specific impairment sits at §41-6a-517, which prohibits operating a vehicle with any measurable controlled substance or metabolite. Medical cardholders have an affirmative defense for metabolite-only cases, but not for actual impairment under §502(1)(b). See DUI & driving for full detail.
