Yes, pepper spray is legal in Massachusetts for self-defense, provided it meets state and local specifications. Residents may purchase and carry canisters under 2% Major Capsaicinoid concentration, with no permit required. However, cities like Boston and Cambridge impose additional restrictions on public carry, and 2026 amendments to the Massachusetts Uniform Fire Prevention and Building Code may further regulate storage in residential units.

- Concentration Limits: State law caps pepper spray at 2% Major Capsaicinoid content; higher concentrations are classified as prohibited weapons under MGL c. 269, § 10(j).
- Canister Capacity: Maximum 36 grams of product per container; larger sizes trigger automatic felony classification under the same statute.
