If MUS was eventually sold in New Zealand and internationally, we wanted to know in advance how its emissions would compare with those of established popular brands (New Zealand Holiday and Marlboro, respectively). It was in other respects a conventional filter cigarette, carrying the Marlboro brand name and unlike previous attempts at safer cigarettes, might just become popular in its three test markets in the United States. Still seeking a cigarette with reduced emissions, we selected Marlboro UltraSmooth (MUS), with a combined CA and carbon filter. The token amount of carbon in the CA filter failed to reduce emissions compared with a CA filter brand of similar tar yield. 9 In 2002 we tested two variants of charcoal filter Mild Seven cigarettes, the world's top selling charcoal filter brand. If, however, VOCs are the dominant toxicants in smoke, then activated charcoal filters which adsorb gases on to their large surface area provide the best chance of lowering smoke toxicity.Ĭigarette company chemists had shown since 1965 that charcoal filters could reduce overall toxicity of cigarette smoke by up to 40% under ISO (International Organization for Standardization) conditions. The ability of smoke particulates, painted on mice, to induce cancer, led to the use of cellulose acetate (CA) filters, which could capture smoke particles by adhesion and let gases and volatiles pass through. When toxicities were combined on the basis of their share of cigarette deaths, VOCs provided up to four‐fifths of the potential emission toxicity. Using this method, and using published potencies and threshold values, we found VOCs contributed more toxicity than tar for carcinogens, respiratory and cardiovascular toxicants. Toxicological risk assessment approaches 3, 4, 5, 6, 7 emphasised volatile organic compounds (VOCs) and included non‐carcinogenic toxicants in assessing the overall total toxicity of smoke. Pryor 1 focused on free radicals as cancer initiators, but these are not routinely measured Hecht emphasised the importance of particulate matter, particularly for lung cancer. It also began testing a moist powdered tobacco called Marlboro Snus in Dallas last year, and also has expanded the test to Indianapolis.Consensus is lacking on which smoke chemicals cause most harm. "That work will continue both for conventional lit-end cigarettes as well as what we would describe as noncombustible tobacco products." Last year, the company began testing of its Marlboro-branded moist smokeless tobacco product - cut tobacco placed in the mouth - in Atlanta and recently expanded to counties in the surrounding metropolitan area. "We remain committed to our overall objective of reducing the harm caused by cigarette smoking," Phelps said. In turn, Philip Morris is looking to growing its business in other tobacco categories and reduced-risk products, Phelps said. over the next few years because of concerns about health, smoking bans and price increases. The company has projected that cigarette sales volume will fall between 2.5 percent to 3 percent in the U.S. The industrywide decline is estimated at 4 percent in the United States. Philip Morris saw a 4.6 percent decline in cigarette sales volume last year, but said that is estimated to be down 3.6 percent when adjusted for calendar differences and other factors. ![]() ![]() Shares of Altria rose 18 cents to $20.96 in midday trading. In the case of Ultra Smooth, it was designed to help us understand consumer acceptance of those particular products' taste and flavor." Phelps said the company had made no claims that the products reduced health risks. "These are test markets and they're designed to help us learn a lot of things. "We did see lower consumer acceptance of those products in some of the test markets," said spokesman Bill Phelps. Marlboro Ultra Lights in Phoenix and North Dakota, and Basic Ultra Lights in Washington state also were discontinued, the company said. Those cigarettes were being tested in Atlanta, Tampa, Fla., and Salt Lake City for more than three years. Philip Morris said it stopped making new shipments of Marlboro Ultra Smooth to wholesalers on April 1. said it pulled the plug on Marlboro Ultra Smooth and Marlboro Ultra Light cigarettes, which used an activated carbon filter to deliver nicotine with potentially less exposure to carcinogens than in conventional cigarettes. The operating company of Altria Group Inc. 1 tobacco company, said Monday it has ended test markets of Marlboro-branded cigarettes that use a high-technology filter.
