     With reference to  FIG. 1 , the smoker knows that fire will flame the filter cotton to produce harmful gases after burning the tobaccos, thus having damage to smoker&#39;s health. To avoid such a problem, the smoker will extinguish and discard a cigarette butt that burning the tobaccos to nearly reach away the cigarette butt of 1-2 cm, thus causing environmental pollution. 
     In addition, the cigarette butt may cause a fire after being discarded to flame objects. 
     A waste prevention cigarette is disclosed in CN 201520125782 and contains a rolling cylinder, cut tobaccos accommodated in the rolling cylinder, a holder connected with the rolling cylinder, and a space defined between the cut tobaccos and the holder and having a filler housed in the space, wherein the filler is a circular ceramics sheet or a circular glass sheet, such that the cut tobaccos do not contact the holder and the waste prevention cigarette is not broken. However, the cigarette is manufactured difficult at high production cost and has heavy weight to increase delivery cost. 
     After smoking the circular ceramics sheet or the circular glass sheet is discarded to have environmental pollution and consumption waste. Furthermore, the burning tobaccos to heat the circular ceramics sheet or the circular glass sheet at a high temperature cause is broken and the smoker is injured by the circular ceramics sheet or the circular glass sheet consequently. 
     Another cigarette is disclosed in U.S. Pat. No. 1,555,320 and is provided with means located intermediate the ends thereof, which operates to extinguish the burning of the cigarette, both the wrapper and the contents, provided the smoking thereof is discontinued. However, after smoking non-flammable substances of the cigarette proximate to a filtration element, harmful gases produce due to the cut tobaccos flames the non-flammable substances at a high temperature, thus causing environment pollution and toxic gases or substance for human body. The cigarette contains the cut tobaccos, the filtration element, and non-flammable substances, so production cost inclusive of the non-flammable substances will increase, and the smoker does not accept such a production cost. Likewise, the non-flammable substances results in consumption waste and environmental pollution, after discarding the cigarettes. 
     The cigarettes of CN 201520125782 and U.S. Pat. No. 1,555,320 have following defects: 
     1. Having resulted in another problem after solving an original problem. 
     2. It is impossible to overcome production cost and to have competitive price in the market. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
