Another problem with attacking the tobacco companies for conspiring to falsely reassure smokers by introducing lower-yield cigarettes is that the government was part of this conspiracy. It approved the testing method and required the inclusion of "tar" and nicotine ratings in cigarette ads.

 Although doubts about the reliability of the ratings were publicly expressed early on, it seemed like a pretty good idea at the time, and the initial epidemiological evidence was promising. Only relatively recently have public health officials started emphasizing that "there is no conclusive evidence of reduced risk from 'low-tar' cigarettes," as the National Cancer Institute put it in 2001.

 By contrast, the health risks of smoking have long been proven beyond a reasonable doubt, something the tobacco companies acknowledged so belatedly that their intransigence became a joke. The question is whether we should now consider it an outrage.

 At the heart of the government's lawsuit is the claim that 33 million Americans were tricked into smoking because they didn't understand the health risks, even though these have been a matter of common knowledge for decades, and/or didn't realize it might be difficult to quit, even though people have been remarking on the difficulty of breaking the tobacco habit for centuries. Because all these smokers were defrauded, the government demands the "disgorgement" of $280 billion in "ill-gotten gains."

Indeed, the Justice Department says this enormous sum -- the proceeds, with interest, from cigarette sales to "youth-addicted" smokers from 1971 to 2001 -- is a conservative estimate. "All of Defendants' sales to all consumers from 1954 to 2001 were inextricably intertwined with this massive scheme to defraud the public," it says, so "the United States would be justified in seeking disgorgement of the proceeds from all sales to people of all ages from 1954 into the future."

 The implication is that no one knew smoking was dangerous until the tobacco companies admitted it. Not only that, but given the industry's history of dishonesty, continuing to sell cigarettes amounts to "racketeering." In this light, Philip Morris's strategy of urging the public not to buy its products makes even more sense.
