Launchers and Projectile Laws
Are Launchers and Projectiles Legal In Massachusetts?
Launchers and Projectiles in MA is Legal.
Legal with Restrictions Massachusetts expressly regulates self-defense spray and says a person under 18 needs a self-defense spray permit; the statute covers pepper spray and similar propelled liquid, gas, or powder.
