i highly doubt vaping will set off a fire alarm because.... there's no smoke.

vapor disappears after like 2 seconds after u exhale it anyway. and vaping leaves close to no smell. even if it does leave a smell, it'll be faint enuff to cover up with a spray of febreeze or something.
ballllin Reviewed by ballllin on . vaporizer in dorm? do you think vaping inside a dorm room would set off the fire alarms? They are extra sensitive at the university i am, there was a big fire many years back. Ive heard even to much hair spray can set them off and burnt popcorn does it easy. Also, when you vape, does it smell a lot? Rating: 5
