Welcome to the club

Tobacco firm Philip Morris is entering the drug delivery market, developing inhalers that have the potential to deliver a variety of drugs. Of course, the science of how to get particles deep into the lungs comes out of the tobacco business.The medical community is not quite sure what stance to take towards Philip Morris, considering the damage its products have done to human health and the company's history of not coming clean on the health risks of smoking.My view is the new products should be judged on their merits. If they're as innovative as they sound it would be a real mistake to let Philip Morris's legacy hold them back.For details, see the lead article in today's Wall St. Journal, "Second Wind; Rx From Marlboro Man: Device That Delivers Drugs, Not Smoke."
