The short answer is yes – pepper‑spray (commonly sold under the brand name “Mace”) remains legal for adults in New Mexico, but the 2026 revisions impose stricter quantity limits, licensing for concealed‑carry, and new resale rules. A 2026 state‑wide survey found that 68 % of residents consider non‑lethal self‑defense tools essential, yet the legislature responded to concerns about misuse by tightening packaging caps and requiring background checks for bulk purchases. Below we break down what the updated statutes mean for everyday users, retailers, and law‑enforcement officers.
Current Legal Framework
Under New Mexico Statutes §30‑9B, non‑lethal defensive agents such as oleoresin capsicum (OC) spray are classified as “peace‑officers’ weapons” rather than firearms. Prior to 2026, any adult could purchase and carry up to 10 ounces without a permit. The law also exempted personal‑use quantities from the state’s weapons licensing scheme, allowing open carry in public spaces.
Key Provisions of the 2026 Amendments
The 2026 legislative package (SB 567 and HB 812) introduced three pivotal changes:
- Quantity cap lowered to 5 ounces per container – aimed at reducing the potential for mass‑discharge incidents.
- Mandatory background check for purchases exceeding 2 ounces – similar to the process for firearms, it is handled through the state’s NICS portal.
- License requirement for concealed carry of any OC spray – applicants must complete a 4‑hour safety course approved by the New Mexico Department of Public Safety.
These adjustments preserve the right to self‑defense while addressing public‑safety concerns highlighted in a 2025 incident where a school‑yard altercation involved a 12‑ounce canister.
Regulatory Requirements for Possession
- Age – buyers must be at least 18 years old; minors may possess only under direct adult supervision.
- Packaging – containers must display tamper‑evident seals and a state‑issued QR code linking to the buyer’s background‑check record.
- Transport – OC spray must be stored in a locked compartment when not in immediate use; concealed‑carry permits exempt this if the carrier can demonstrate a legitimate self‑defense need.
Failure to comply can trigger civil penalties, but criminal liability arises only when the spray is used offensively rather than defensively.
Penalties for Misuse
- First‑offense unlawful discharge – classified as a misdemeanor, punishable by up to 12 months incarceration and a $1,000 fine.
- Repeat offenses or assault with OC spray – escalated to a felony, with a maximum sentence of three years and a $5,000 fine.
- Retail violations – businesses that sell beyond the 5‑ounce limit without conducting a background check face a $2,500 per‑day fine until compliance is achieved.
Practical Implications for Citizens
For most New Mexicans, everyday self‑defense remains straightforward: purchase a 5‑ounce canister from a licensed dealer, complete the brief background check if buying more than 2 ounces, and carry openly or concealed with the appropriate permit. Law‑abiding owners who follow the packaging and transport rules are unlikely to encounter legal trouble, while those who ignore the new limits risk escalating penalties.
What is the maximum legal size of Mace a civilian can buy in New Mexico?
Adults may purchase containers up to 5 ounces. Any purchase exceeding 2 ounces triggers a mandatory background check through the state’s NICS system.
Do I need a permit to carry pepper spray openly in public?
No permit is required for open carry of a 5‑ounce canister, provided it is stored in a locked compartment when not in use. A concealed‑carry permit is required only if the spray is carried in a pocket or bag that is not visibly secured.
Can minors possess pepper spray at home?
Minors may possess pepper spray only under direct adult supervision. The law does not allow independent ownership by anyone under 18.
How does the 2026 law affect retailers of pepper spray?
Retailers must verify the buyer’s age, ensure the product does not exceed 5 ounces, and conduct a background check for sales over 2 ounces. They must also affix a state‑issued QR code to each container.
What are the criminal consequences if I use pepper spray offensively?
Using pepper spray to attack another person is a misdemeanor on the first offense, punishable by up to 12 months in jail and a $1,000 fine. Repeated or aggravated assaults elevate the charge to a felony with harsher penalties.
