Differentiation of surface is utilized for the prevention or arrest of forward finger edge slippage along the surface of a cigarette under new perception and consideration of all significant factors, including the human factor. Provision is sometimes included for automatic extinguishing of the cigarette or destruction of its smokable utility prior to dissipation of the means against slippage. A cigarette is manufactured having predetermined control against its being smoked or burned the full length of its tabacco content.
