Answer: 
Hello Kae. The extinguisher is not designed specifically for cigarette smoke and is made to avoid going off for a small amount of smoke, say, if the toast burns in the toaster. However, if there is enough thick smoke on the ceiling that the smoke flows into the back side edges of the alarm, the alarm will go off. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Rated 4.5 out of 5 by 161 reviewers.
Rated 4.0 out of 5.0 by One out of two ain't bad No problem with the product. However, I had ordered two of them online, only to find that one was defective (broken battery contact). This necessitated my having to go to the store for an exchange, which is exactly what I was hoping to avoid by ordering online! June 21, 2016
Rated 5.0 out of 5.0 by Fabulous product ! This product was my first choice when shopping for a replacement. The price was reasonable, the style was sleek. The color is a neutral white which blends with any wall color. Easy installation, comes with batteries and screws. The voice activation is an added feature and is an exceptional idea in emergency circumstances. I rate this product five stars! I have bought six for my entire apartment building! June 17, 2014
Rated 5.0 out of 5.0 by This product is easy to install. I purchased this product to replace an expired smoke detector in a family room containing a fire place. This unit was very easy to install with basic tools found in any home and has a front panel that makes battery replacement a snap. The unit is neutral color and blends in well. It does not give false alarms as many units I have owned in the past did. I highly recommend this unit. March 18, 2014
Rated 5.0 out of 5.0 by Excellent product My last one lasted as long as it should have, something like 8 or 10 years. And then started chirping. Very pleased with the new alarm. Tested it and it worked fine. The best part is, I was able to pop off the old Kidde alarm and pop on the new one without having to install the base, saving me some difficulty. March 22, 2016
Rated 5.0 out of 5.0 by Kidde CO/Fire works perfectly! I replaced my Kidde CO/fire alarms after I had a CO problem in my apartment. Woke me up (loudly) when I was sleeping and the alarm system made sure I was safe! Excellent product. The voice alarm for which aspect is alarming is very useful since I was feeling pretty disorientated. Only good things to say about this! August 11, 2013
Rated 4.0 out of 5.0 by A peace of mind for fire and carbon monoxide Easy to install and I feel better knowing that my wife and I are protected January 14, 2014
Rated 5.0 out of 5.0 by Good smoke & Carb detector Very easy to install and lithium batteries will last 10 years. January 5, 2016
Rated 5.0 out of 5.0 by CO/Smoke Detector A twofer and easy to install. Seems like a good product to me. December 8, 2015
