Maryland sits in a middle tier โ stun guns are legal after a background check at purchase, but no ongoing permit is required. Every major Maryland campus bans them, making a stun gun an impractical choice for Maryland college students.
What Maryland Law Actually Says
Maryland Criminal Law Code ยง 5-133 requires a background check at the point of stun gun purchase. This is a point-of-sale check, not an ongoing license. Adults 18+ who pass the background check may purchase and possess a stun gun.
Prohibited locations include school property and places where firearms are banned.
Campus Reality
University of Maryland, Johns Hopkins, Towson, UMBC, and Loyola Maryland all prohibit stun guns on campus under their weapons policies.
What to Carry Instead
For Maryland students, a personal alarm and pepper spray are the right combination. Pepper spray is legal for Maryland adults 18+ with no background check required โ simpler than buying a stun gun. The She's Birdie Personal Alarm ($29.99) is unrestricted everywhere. The SABRE Campus Safety Pepper Gel ($11.99) is the top choice for outdoor carry.
Maryland is unique: Stun guns require a background check at purchase but no permit. Pepper spray requires neither. For college students, pepper spray is the simpler legal choice.

Important: Campus policies change. Always verify current pepper spray rules directly with your student's campus police department or housing office before move-in day. State law sets the minimum โ individual colleges can be more restrictive.
