Cigarette and Cannabis smoke do not set off smoke alarms unless the smoke is very thick in the air or blown directly into the detector. Smoke alarms are designed to not go off from these types of smoke
DRybes Reviewed by DRybes on . on smoke alarms... quick question... my bedroom's got a pretty high ceiling with a smoke alarm over the entrance about 20ft from my window... how much smoke will set it off? would I be fine tokin' out the window? Rating: 5
