 Altria Group Inc., the maker of Marlboro, fell on news of a possible ban on menthol cigarettes in the U.S., which account for about 20 percent on the company’s profit. 
  
 A senior U.S. Food and Drug Administration official said last week that the agency is looking at restricting menthol in traditional cigarettes. Doing so would be a step toward eliminating or tightly limiting use of the popular cigarette flavor, something the FDA has been considering for some time. More aggressive regulation of nicotine has been a major priority for Commissioner Scott Gottlieb. 
  
 An Altria spokesman said Monday it was premature to comment absent an FDA announcement. Shares of the company, which makes Marlboro for the U.S. market, fell as much as 3.6 percent to $61.14 Monday in New York. The stock had declined 11 percent this year through Friday’s close. 
  
 British American Tobacco Plc, whose products include Newport, fell the most in more than four years in London, destroying 8.4 billion pounds ($10.8 billion) of market value. Menthol products sold in the U.S. account for about a quarter of the company’s earnings. 
  
 “BAT is the most exposed name to the potential risk,” wrote Richard Taylor, an analyst at Morgan Stanley who estimates that U.S. menthol cigarettes account for 25 percent of total earnings. 
  
 A ruling on menthol in traditional cigarettes would come in a separate action from the FDA’s planned restriction on e-cigarette flavors, according to the official. 
  
 ‘Multiyear’ Process 
  
 “We are not aware of anything that has changed to suggest the FDA would deviate from its existing multi-year comprehensive, rule-making process on flavours in tobacco products, which includes menthol,” BAT spokesman Simon Cleverly said in a statement. If the agency indicates it seeks “to regulate menthol cigarettes, any such proposal will have to go through the multiyear rulemaking process,” he said. 
  
 The potential ban steps up the FDA’s campaign against youth smoking. Clove cigarettes were previously taken off the market, and now the agency is taking a tougher approach to alternatives, too. The FDA has been targeting flavored tobacco products as studies indicate that teens who smoke menthol cigarettes consumed close to twice as many weekly compared with non-menthol users. 
  
 Not all analysts think a ban is likely. Jefferies analyst Owen Bennett said such a move is improbable and would take years to implement. 
  
 Legal Challenge 
  
 Tobacco companies would probably mount a legal challenge that would delay the process, Gerry Gallagher, an analyst at Deutsche Bank, also said. 
  
 The decline in BAT shares illustrates that while the Lucky Strike maker is expanding into vapor and heated-tobacco products, its main business is still cigarettes. 
  
 Imperial Brands Plc declined as much as 5 percent. The Winston maker gets about 15 percent of earnings from menthol brands such as Kool and Salem in the U.S., according to Jefferies. The proportion is about 20 percent for Altria, according to the firm. 
  
 Imperial will continue to engage with the FDA about menthol cigarettes, but will not comment further until there’s a formal update from the agency, spokesman Simon Evans said by email. 
  
 Newport is BAT’s largest menthol brand and accounts for about 40 percent of U.S. sales, according to Duncan Fox, an analyst at Bloomberg Intelligence. Tobacco companies won an exception for menthol, the most popular flavored cigarette and the one preferred by black smokers, when a federal law banned other flavors in 2009. 
  
 BAT shares have dropped 40 percent this year, the biggest drop in at least two decades. They have had only two annual declines in the past 19 years. 
  
 — With assistance by Lisa Pham ||||| In a landmark move bound to further shake the tobacco industry, the Food and Drug Administration plans to propose a ban on menthol cigarettes next week as part of its aggressive campaign against flavored e-cigarettes and some tobacco products, agency officials said. 
  
 The proposal would have to go through the F.D.A. regulatory maze, and it could be several years before such a restriction took effect, especially if the major tobacco companies contest the agency’s authority to do so. None of the major tobacco companies would comment on the possibility of barring menthol cigarettes at this early stage. 
  
 But such a move has been long-awaited by public health advocates, who have been especially concerned about the high percentage of African-Americans who become addicted to menthol cigarettes. 
  
 Dr. Scott Gottlieb, the agency’s commissioner, would not comment publicly on the proposal on Friday. But in a recent interview, he said the F.D.A. was revisiting the issue, one that had been weighed in previous administrations. “It was a mistake for the agency to back away on menthol,” he said earlier this fall. |||||
Output:
The US Food and Drug Administration is reportedly proposing a ban on menthol cigarettes. Per the New York Times, the agency said the proposal would come this week as part of a more aggressive stance against the tobacco. It's unclear how long it would take for such a plan to take effect and tobacco companies could drag out the process by challenging a ban. While regulators under previous administrations have considered similar moves, President Trump's current FDA commissioner, Scott Gottlieb, has made the reduction of smoking-related disease a priority. Menthol cigarettes have been identified by some experts as an even greater health risk than non-flavored cigarettes because the minty compound makes smoking feel less harsh and increases the potential for addiction. Gottlieb has not commented on the issue. As Bloomberg notes, news of the potential ban sent stocks of Marlboro maker Altria Group Inc. falling on Friday. Shares of British American Tobacco, which makes Newport cigarettes, also took a nosedive, falling more on Friday than in the last four years. (The FDA has also signaled it plans to restrict sales of e-cigarettes.)
