PRINCETON ― U.S. President Barack Obama’s doctor confirmed last month that the president no longer smokes. At the urging of his wife, Michelle Obama, the president first resolved to stop smoking in 2006, and has used nicotine replacement therapy to help him. If it took Obama, a man strong-willed enough to aspire to and achieve the U.S. presidency, five years to kick the habit, it is not surprising that hundreds of millions of smokers find themselves unable to quit.

Although smoking has fallen sharply in the U.S., from about 40 percent of the population in 1970 to only 20 percent today, the proportion of smokers stopped dropping around 2004. There are still 46 million American adult smokers, and smoking kills about 443,000 Americans each year. Worldwide, the number of cigarettes sold ― six trillion a year, enough to reach the sun and back ― is at an all-time high. Six million people die each year from smoking ― more than from AIDS, malaria, and traffic accidents combined. Of the 1.3 billion Chinese, more than one in 10 will die from smoking.

Earlier this month, the U.S. Food and Drug Administration announced that it would spend $600 million over five years to educate the public about the dangers of tobacco use. But Robert Proctor, a historian of science at Stanford University and the author of a forthcoming blockbuster entitled Golden Holocaust: Origins of the Cigarette Catastrophe and the Case for Abolition, argues that to use education as one’s only weapon against a highly addictive and often lethal drug is unpardonably insufficient.

“Tobacco control policy,” Proctor says, “too often centers on educating the public, when it should be focused on fixing or eliminating the product.” He points out that we don’t just educate parents to keep toys painted with lead-based paints away from their children’s mouths; we ban the use of lead-based paint. Similarly, when thalidomide was found to cause major birth defects, we did not just educate women to avoid using the drug when pregnant.

Proctor calls on the FDA to use its new powers to regulate the contents of cigarette smoke to do two things. First, because cigarettes are designed to create and maintain addiction, the FDA should limit the amount of nicotine that they contain to a level at which they would cease to be addictive. Smokers who want to quit would then find it easier to do so.

Second, the FDA should bear history in mind. The first smokers did not inhale tobacco smoke; that became possible only in the 19th century, when a new way of curing tobacco made the smoke less alkaline. That tragic discovery is already responsible for about 150 million deaths, with many times that toll still to come, unless something drastic is done. The FDA should therefore require that cigarette smoke be more alkaline, which would make it less easily inhaled, and so make it harder for cigarette smoke to reach the lungs.

Much of Proctor’s book, which will be published in January, is based on a vast archive of tobacco-industry documents, released during litigation. More than 70 million pages of industry documents are now available online.

The documents show that, as early as the 1940s, the industry had evidence suggesting that smoking causes cancer. In 1953, however, a meeting of the chief executives of major American tobacco companies took a joint decision to deny that cigarettes are harmful. Moreover, once the scientific evidence that smoking causes cancer became public, the industry tried to create the impression that the science was inconclusive, in much the same way that those who deny that human activities are causing climate change deliberately distort the science today.

As Proctor says, cigarettes, not guns or bombs, are the deadliest artifacts in the history of civilization. If we want to save lives and improve health, nothing else that is readily achievable would be as effective as an international ban on the sale of cigarettes. (Eliminating extreme poverty worldwide is about the only strategy that might save more lives, but it would be far more difficult to accomplish.)

For those who recognize the state’s right to ban recreational drugs like marijuana and ecstasy, a ban on cigarettes should be easy to accept. Tobacco kills far more people than these drugs.

Some argue that as long as a drug harms only those who choose to use it, the state should let individuals make their own decisions, limiting its role to ensuring that users are informed of the risks that they are running. But tobacco is not such a drug, given the dangers posed by secondhand smoke, especially when adults smoke in a home with young children.

Even setting aside the harm that smokers inflict on nonsmokers, the free-to-choose argument is unconvincing with a drug as highly addictive as tobacco, and it becomes even more dubious when we consider that most smokers take up the habit as teenagers and later want to quit. Reducing the amount of nicotine in cigarette smoke to a level that was not addictive might meet this objection.

The other argument for the status quo is that a ban on tobacco might result in the same kind of fiasco as occurred during Prohibition in the U.S. That is, like the effort to ban alcohol, prohibiting the sale of tobacco would funnel billions of dollars into organized crime and fuel corruption in law-enforcement agencies, while doing little to reduce smoking.

But that may well be a false comparison. After all, many smokers would actually like to see cigarettes banned because, like Obama, they want to quit.
