A user engageable device disposed within the tobacco burning path of a smoking article's
ember at a pre-selected point. The device may include a visual and / or audible and / or olfactory warning component which alerts the user in response to a
proximate ember. This provides one or a combination of a visual, audible, or olfactory alert to the user that the
ember has reached a predetermined point. The device is preferably in the form of a sleeve frictionally engageable around the smoking article, but can also may be engaged upon or impregnated into a wrapper of the article's cylinder. Alternatively, the sleeve type device may be disposed within the wrapper. Alternatively the indicator material may also be in the form of selectively placed integrated or stick-on patches.
