Yes, pepper spray is legal in Maine for self-defense, but its purchase, possession, and use are subject to specific state and municipal restrictions enforced by the Maine Criminal Justice Academy and local ordinances.
Maine permits the sale and possession of pepper spray for personal protection, provided it meets the state’s definition of a “non-lethal defensive spray.” Devices must contain no more than 2% capsaicinoids and cannot exceed 10% oleoresin capsicum by weight. The Maine Attorney General’s Office, through its 2024 regulatory guidance, clarifies that pepper spray is not classified as a firearm or dangerous weapon under state law, but local municipalities retain limited authority to regulate its use in public spaces. Violations may result in misdemeanor charges under Title 17-A, § 1057.
Key Regulations for Pepper Spray in Maine
- Concentration Limits: Only sprays with ≤2% capsaicinoids and ≤10% oleoresin capsicum are lawful. Higher concentrations are treated as prohibited weapons under 15 M.R.S. § 1058.
- Age Restrictions: Purchasers must be 18 or older, verified through ID checks at licensed retailers, per 25 M.R.S. § 1532(3).
- Use Prohibitions: Discharging pepper spray in a manner likely to cause public alarm or bodily harm violates 17-A M.R.S. § 504-A, with penalties escalating if minors are endangered.
Retailers must maintain sales records for five years, as mandated by the Maine Department of Public Safety’s 2026 compliance directive. Failure to comply may result in civil penalties up to $1,000 per violation.
