The invention discloses a variable-ventilation filter tip and a cigarette. The filter tip includes a filter element and a coating layer. The coating layer wraps the filter element. The filter element includes a smoke inlet end and a smoke release end. A phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a plurality of first ventilation holes are arranged in the phase-change ventilation area, and a plurality of second ventilation holes are arranged in the non-phase-change ventilation area. Outside air penetrates through the coating layer through the first ventilation holes and the second ventilation holes to enter a part of the filter element. A part in the filter element close to the smoke inlet end is provided with a starch tube. A phase-change material is filled in the first ventilation hole. A phase-change temperature of the phase-change material ranges from 45° C. to 60° C.

A smoking cessation device that utilizes a structured, flexible tube similar in size and shape to a standard cigarette. The tube is impregnated with flavored oils for the enjoyment of the user. The method of producing the smoking cessation device is performed by mixing the flavored oil with a high-proof alcohol and spraying the mixture onto the tube. After the alcohol evaporates, the tube retains the flavored oils, providing a pleasant taste to the user. A user can use the smoking cessation device by biting and or chewing on the end of it to restrict air flow making it feel similar to a cigarette.

A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.
