Patent number: 5713376Abstract: Cut tobacco used for processing cigarettes or other smoking articles is reacted with an agent such as an oxidant or subject to an extraction/removal process for a suitable period of time, dependent upon the nicotine content, the oxidant employed and the reaction temperature or extraction condition, or distillation, such that the nicotine embedded in the leaf is then converted into nicotinic acid or niacin. Sufficient conversion or extraction or distilled is allowed to occur so that either no nicotine or only a minimal amount of free nicotine remains in the smoking article. Upon intake into the lungs and hence the blood stream of the smoker or other tobacco user, the smoker or tobacco user will result in a blood plasma content of nicotine ranging from 0 to less than about 5 nanograms per milliliter of blood plasma. This effectively insures that the addictive process in smoking or other tobacco intake cannot he initiated or maintained. Nicotinic acid or niacin is not an addictive component of the tobacco.Type: GrantFiled: May 13, 1996Date of Patent: February 3, 1998Inventor: Carl Berger

The cover layer has an area weight of 20 to 60 g/m.sup.2, a raw density of 0.5 to 0.9 g/cm.sup.3, an air permeability of 10 to 250 CU, a filler material content in the range of 10 to 60 percent, and a burn promoting salt content in the range of 0 to 5 percent. The inner layer has an area weight of 6 to 20 g/m.sup.2, a raw density of 0.7 to 1 g/cm.sup.3, and an air permeability of 0 to 12 CU. The layers are wet laminated in a paper machine. Smoking articles with such a wraper do not experience a change in taste of the main smoke flow nor any spot development, and they afford an attractive ash tube or sheath. The time period for extinguishing the smoking article can be varied within wide limits. Moreover a drastic reduction of secondary smoke flow can be noted.Type: GrantFiled: November 30, 1989Date of Patent: January 15, 1991Assignee: Julius Glatz GmbHInventor: Walter Riedesser
