It probably varies....

I'm at university at the moment and I have a smoke detector in my room which isn't sensitive at all, I have had about 4 people smoking in here before and it didn't go off, I just have the window open and I'm fine.

Ask some other people around your campus, they might be able to tell you wether its a good idea or not!
mattisnotonfire Reviewed by mattisnotonfire on . How sensitive are smoke detectors? Now that im in college, i have to worry about smoking around smoke detectors. I just now smoked in the bathroom with the shower running hot water, and i taped a bag around what could be a smoke detector in the bathroom. There are also two smoke detectors in the hall outside the bathroom that i didnt tape up, but i put a towel underneath the door so that no smoke could get outside the door. So what im asking is, is this a safe spot? Exactly how sensitive is a smoke detector and how much smoke Rating: 5
