The Sheriff Transition

The Maricopa County Sheriff’s Office (MCSO) has been led by three sheriffs in this century:

Joe Arpaio (1993–2017) — six terms, "America’s Toughest Sheriff," outdoor "Tent City" jail, pink-underwear program. Found by the U.S. Department of Justice in 2011 to have engaged in "a pervasive culture of discriminatory bias against Latinos." Federal court monitor (Judge G. Murray Snow) remains active. Held in criminal contempt of court in 2017 (later pardoned by President Trump).
Paul Penzone (2017–January 12, 2024) — Democrat, former Phoenix Police sergeant, defeated Arpaio in 2016 and re-won in 2020. Closed Tent City in 2017. Held in contempt of court in November 2022 by Judge Snow for failing to clear MCSO’s internal-affairs backlog. Resigned January 12, 2024 to take a job at Blue Cross Blue Shield. Chief Deputy Russ Skinner served as interim sheriff.
Jerry Sheridan (January 1, 2025–present) — Arpaio’s former chief deputy, won the November 2024 general election as a Republican with over a million votes, defeating Democrat Tyler Kamp.

The Federal Court Monitor

MCSO operates under a longstanding federal court monitor for racial profiling, in place since the post-2011 DOJ findings against the Arpaio administration. The monitor’s mandate covers traffic-stop documentation, internal-affairs review, training, and bias-related policies.

Sheridan in early 2025 told KJZZ that the court monitor was "the part of the problem because the court monitor is really the one that needs to do that." He has stated his desire to terminate the monitorship.

The monitor’s continuation depends on Judge Snow’s assessment of MCSO’s compliance with the underlying consent decree. Sheridan’s administration has not (as of April 2026) cleared the compliance bar that would justify ending the monitor.

Cannabis as an MCSO Priority

Cannabis enforcement is not an MCSO priority publicly under Sheridan. The agency’s stated focus is immigration enforcement and ICE coordination, with secondary priorities around violent crime and quality-of-life issues. Cannabis is a low-priority offense at the agency level.

However, "low priority at the agency level" does not mean "no enforcement at all." Several caveats:

Routine traffic stops in unincorporated Maricopa County can produce probable-cause searches on cannabis odor (Arizona case law on this is evolving but odor remains a basis for search in most contexts).
Cannabis discovered during stops on other offenses (DUI, expired registration, traffic violations) is typically charged.
Larger-quantity possession (over the 1 oz adult-use limit), distribution evidence, or sale to minors is prosecuted.
Cannabis consumption in vehicles or in public places observed by deputies is cited.

Where MCSO Patrols

MCSO’s primary patrol jurisdiction is unincorporated Maricopa County, including:

Stretches along I-10, I-17, and Loop 303
Unincorporated areas between municipal lines (e.g., between Phoenix and Litchfield Park, between Mesa and Apache Junction)
Some county-island jurisdictions inside cities (e.g., the three Mesa-area county-island dispensaries that operate under Maricopa County ordinance rather than Mesa city ordinance)
Maricopa County jails

Inside Phoenix, Mesa, Scottsdale, Tempe, Glendale, Chandler, Gilbert, Peoria, and other incorporated cities, the local police department patrols. MCSO is the back-up agency, not the primary.

Practical Implications

If you live in or transit through unincorporated Maricopa County, expect routine traffic enforcement and no cannabis-specific protections beyond state law.
For freeway driving (I-10, I-17, Loop 303, Loop 202), the agency is typically Arizona DPS (state troopers), not MCSO. Same Arizona state law applies.
For the Maricopa County jail system, cannabis possession will be inventoried and charged. AMMA cards do not protect against this.
For Sheridan-era posture changes: MCSO’s cannabis policy under Sheridan remains under change. Predictions should be treated as preliminary. Verify current MCSO operational guidance via local press coverage.

The Tent City Legacy

The infamous outdoor "Tent City" jail (where Korean War surplus tents held inmates in 110°F+ summer heat) was closed by Penzone in 2017. Sheridan has indicated openness to revisiting various Arpaio-era practices but has not (as of April 2026) reopened Tent City or restored the pink-underwear program. The Maricopa County jail system continues to operate under significant federal-court oversight related to use of force, healthcare, and other conditions of confinement.

Cannabis-Related Encounters: What to Do

If you are stopped by an MCSO deputy in unincorporated Maricopa County and cannabis is at issue:

Be calm and cooperative. Keep your hands visible.
Acknowledge legal possession if true. If you have under 1 oz and are 21+, you are legally compliant under Arizona state law. State this once.
Do not consent to a search. The deputy may search anyway based on cannabis odor or other probable cause, but consent waives certain later challenges.
Do not volunteer information. "I’m a 21+ adult with under 1 oz of cannabis purchased today at a licensed Arizona dispensary, and I have my receipt" is sufficient. Do not elaborate.
If cited or arrested, contact a Phoenix-area cannabis attorney. Tom Dean (criminal defense, Phoenix) and the Rose Law Group (Scottsdale) are widely cited.
