The Road to HB 2
New Mexico's legalization did not happen on the first attempt. During the 2021 regular session, a legalization bill passed the House but stalled in the Senate. Governor Michelle Lujan Grisham — who had made legalization a top priority — refused to let the effort die. She convened a special legislative session in June 2021, focused specifically on cannabis legalization.
The special session produced two companion bills:
- HB 2 — the Cannabis Regulation Act: established the regulatory framework, licensing system, tax structure, possession limits, home cultivation rights, and the Cannabis Control Division.
- SB 2 — the expungement companion: provided automatic record clearing for past cannabis convictions that would no longer be crimes under the new law.
The Vote
HB 2 passed the House 38–32 and the Senate 22–15. Governor Lujan Grisham signed both bills on June 29, 2021. The debate was intense — opponents raised concerns about impaired driving and youth access, while supporters emphasized racial justice, economic opportunity, and the failure of prohibition.
New Mexico became the 18th state to legalize recreational cannabis and the 5th to do so through legislative action rather than a voter ballot initiative. The others at that time were Vermont, Illinois, New York, and Connecticut.
What HB 2 Created
The Cannabis Regulation Act is codified at NMSA 1978, Chapter 26, Article 2C. Key provisions include:
- Legal possession: 2 oz flower, 16g concentrate, 800mg edibles in public; no limit at home.
- Home cultivation: 12 plants per person (6 mature), 12 mature per household.
- Consumption lounges: Licensed on-site consumption areas — one of the first states to authorize these.
- Cannabis Control Division (CCD): Created within the Regulation & Licensing Department to oversee all licensing, enforcement, and regulation.
- Tax structure: 12% excise tax (stepping to 13% in 2026), plus state and local gross receipts tax (GRT) averaging 7–9%.
- Social equity: Priority licensing for communities disproportionately impacted by cannabis prohibition.
- Micro-business licenses: Lower-barrier licenses designed for small operators.
The 273-Day Sprint
From signing on June 29, 2021 to the first recreational sale on April 1, 2022, New Mexico had just 273 days to build an entire regulatory framework from scratch. The CCD worked at breakneck speed — drafting rules, processing license applications, and preparing existing medical dispensaries for dual-use sales. This was one of the fastest seed-to-sale timelines in U.S. cannabis history.
The companion bill SB 2 provided for automatic expungement of past cannabis convictions that would no longer be crimes under the Cannabis Regulation Act. This was a key social justice component of the legalization package.
The Expungement Promise
SB 2 directed courts to identify and expunge eligible convictions. The process was designed to be automatic — individuals would not need to file petitions. However, implementation has been uneven, with some courts moving faster than others. Advocates continue to push for full completion of the expungement process.
Amendments and Updates
Since its passage, the Cannabis Regulation Act has been amended several times:
- 2023: Adjustments to licensing caps and micro-business definitions.
- 2025: HB 230 added employment protections for medical cannabis patients, prohibiting random drug testing of registered patients and requiring observable impairment for adverse employment action.
- 2026: The excise tax rate stepped up from 12% to 13% as scheduled in the original act.
