Personal protection devices like pepper spray, stun guns, or collapsible batons are legal to carry in Oregon and on the UO campus, as long as they are used legally and not misused. If it's sold over the counter, it's OK. Certain knives and other devices are illegal to carry.
Anyone who carries personal protection devices should get training on how to use them before being in a crisis, and consider that the devices can be used against them.
Guns are not allowed on campus except for on-duty law enforcement.
