Five years ago today, CVS pulled all tobacco products from it shelves, shutting off a $2 billion a year business, but creating a path for the company’s transformation into a health care provider (and ultimately, its acquisition of Aetna.) The move led to a measurable decline in cigarette sales and smoking. It was a sterling example of a company pursuing purpose at the expense of short-term profit, leading to benefits for both the business and society.

This morning, CVS is launching a new $50 million campaign to help stop teen vaping, and create the first tobacco-free generation. The rise of teen vaping “is something I am personally very worried about,” CEO Larry Merlo told me Friday. He cited a study showing “78% of school age kids who are vaping are likely to begin smoking before they finish high school.”

Are we backsliding on smoking? “In some respects, I do see us going backward,” Merlo replied. The company plans to boost smoking cessation programs both though CVS Caremark and through Aetna managed care plans.

The tobacco decision five years ago “was foundational to our growth as a health care company,” Merlo said. “It served as a point of validation that we are a very credible health care provider.” He said it also had a big impact on the firm’s culture, engaging employees across the company. “It brought our purpose to life in a very meaningful way.” A lesson there for others?

Among those attending: Dow CEO Jim Fitterling, Impossible Foods CEO Pat Brown, Esquel Chair Marjorie Yang, Energy Innovation CEO Hal Harvey, AeroFarms CEO Dave Rosenberg, and environmentalist extraordinaire Bill McDonough. We’ll be reporting from there the rest of the week.

Brexit Crunch

Today, British lawmakers will introduce legislation that would effectively block a no-deal Brexit at the end of October, forcing Boris Johnson's government to ask the EU for another extension until the end of January if no deal has been agreed by mid-October. Johnson has warned that, if the vote passes, Conservatives who voted for the blockage will be booted out of the party, and a general election will be held on October 14, to block the blocking legislation. Sterling fell on that threat, though two-thirds of lawmakers would need to back the call for a fresh election for it to occur. BBC
