College	City	Pepper Spray	Personal Alarm	Notes

After initial reporting suggested a ban, CSU officials confirmed via email that pepper spray and Tasers are permitted for self-defense.

Colorado has permissive pepper spray laws and a strong outdoor and self-defense culture. Adults 18 and older may carry self-defense sprays freely, and Colorado's major universities follow that permissive stance.

What Colorado Law Actually Says

Colorado Revised Statutes do not restrict civilian carry of self-defense chemical sprays. Key facts:

Age: 18 or older
Size: No state limit
Concentration: No state limit
Permit: None required

The Denver Urban Factor

Several Colorado universities are in or near Denver — DU, MSU Denver, CU Denver, and Regis. Urban Denver students benefit from personal alarms for daily transit use alongside pepper spray for close-range protection.

Verify your dorm policy with your RA before bringing pepper spray into a residential building.

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 — individual colleges can be more restrictive.
