How do smoke detectors differentiate between cigarette smoke and hazardous fire? Like when my smoke detector goes off when I’m cooking things but not with cigarette smoke.

Generally smoke detectors should be going off if they detect cigarette smoke. If they’re not you either have a faulty smoke detector or there wasn’t enough smoke for it to go off

Smoke detectors don’t differentiate between different types of smoke usually. Often times they work by detecting large amounts of particles in the air, and when it reaches a threshold it triggers the alarm.
