Dr. Scott Gottlieb’s forthcoming departure from the U.S. Food and Drug Administration has sparked confidence in the tobacco industry while also leaving some uncertainty about what’s next on the regulatory front.

While there has been no immediate changes to policy or enforcement action based on Gottlieb’s decision to leave the agency, stock prices for tobacco companies rose Tuesday afternoon following the announcement. According to Nasdaq, Altria’s stock rose by 1.5 percent and British American Tobacco’s stock rose 1.9 percent.
