Reynolds wants changes to warning label on smokeless tobacco products


Winston-Salem-based R.J. Reynolds Tobacco Co. wants the U.S. Food and Drug Administration to make changes to one of the warning labels on smokeless products, the Winston-Salem Journal reports.

The change would say that while smokeless tobacco is not safe, it "presents substantially lower risks to health than cigarettes.” The warnings currently say smokeless tobacco "is not a safe alternative to cigarettes.”

Smokeless tobacco products include moist snuff, snus, dissolvable products and e-cigarettes.

The FDA will hold a hearing Monday on how the agency should monitor and regulate smoking cessation and nicotine-replacement therapy products, according to The Business Journals.

Less Harmful Constituents When Heating Tobacco at Lower Temperatures?


Many of the harmful constituents found in the smoke from a conventional cigarette result from the burning of tobacco. Lowering the temperature at which the "smoke" is generated means that nicotine and some aroma compounds are still released, but the user may no longer be exposed to some of the combustion products that are generated by the burning of tobacco and which may contribute to the risk of smoking-related diseases. By measuring the air flow through a tobacco matrix that is heated in a new type of smoking product it may be possible to determine which constituents are released, at which time and at which location.

The research of David Lopez Penha of the University of Twente is an important first step in understanding the physics of smoking.

Lopez Penha has investigated flows in porous media, derived from cast leaf tobacco biomass. He has developed a model that predicts the flow of hot air through this highly complex porous medium. For this purpose the 3-D pore geometry was reconstructed using microCT-scans (micro-Computed Tomography). For the first time, his work provides some insight into the way that air flows through the small pores inside the tobacco plugs: this could open up a new way of determining which substances may be released and at what concentrations, during the flow of air through heated tobacco matrices, according to Science Daily.

Bar owners protest state smoking ban


State bar owners have been raising opposition to the statewide smoking ban in bars and restaurants, claiming to legislators and courts that the ban is ruining their business.

While restaurants have come to appreciate the ban’s unforeseen effect of increasing sales, the president of the N.C. Bar, Pub & Tavern Association recently wrote a letter to the N.C. General Assembly urging legislators to exclude profit-making bars from the ban.

Sales at Gate City Billiards Club, a private club in Greensboro, have decreased 25 percent since the 2010 ban , said Don Liebes, the club’s owner and president of the association.

“We’re different from restaurants,” he said, adding that 75 percent of his customers smoke. “The ban put us at a competitive disadvantage.”

Because of the ban, the club has lost $30,000 since January, Liebes said. On an average Friday night, the club now serves 30 fewer customers — about a 15 percent decrease.

“We’re not making any money,” he said. “It’s only a matter of time before we go under.”

Bar and restaurant owners in the state were initially concerned that the ban would be an excessive regulation, said Brad Hurley, co-owner of the 42nd Street Oyster Bar & Seafood Grill in Raleigh and chairman-elect of the N.C. Restaurant and Lodging Association.

But some restaurant owners now say the ban has boosted sales. In a letter sent Oct. 5 by the restaurant association to the legislature, one restaurant owner reportedly observed a 25 to 30 percent growth in sales since 2009, reports The Daily Tar Heel.
