Are low tar cigarettes safer?

Ask Dr. Bill

Dear Dr. Bill,

I switched to smoking low-tar cigarettes almost 20 years ago rather than quit entirely as I thought they delivered less tar and were thus less risky for causing cancer than regular cigarettes. I was really shocked to learn on 60 Minutes II (February 21st) that it doesn't make any difference what type of cigarette you smoke!! Did you know this?

Dear Chagrined,
I saw the same program and took some notes so I could share some of the info to readers like you. It's been over 23 years since I smoked my last cigarette. After the federal government began testing cigarettes for tar and nicotine in 1967, I also had started smoking so-called "light" cigarettes until I finally came to my senses and quit entirely. 60 Minutes II reported that "The idea of a less harmful cigarette is still so powerful that now more than 80 percent of all cigarettes sold in America are low-tar brands.....What smokers don't know is that the government's low-tar number on the pack has almost nothing to do with how much tar they're inhaling. It only tells you how much tar is being delivered to a smoking machine, not to human smokers." The result? Since testing began, more than 12 million Americans have died from smoking- related diseases!

I wasn't a bit surprised to learn that the tobacco companies knew that the tar-number on each pack was useless info... but, what I didn't know is that the federal government also knew!! The machine used for the U.S. Federal Trade Commission test measures addictive nicotine and cancer-causing tar. The FTC publishes results brand by brand and, for 35 years, tobacco companies have used those figures as a powerful sales tool. Dr. David Burns, writer of the yearly surgeon general's report on smoking since 1975, noted that the FTC test doesn't measure the tar that people actually get, explaining, "If you change the way you smoke that cigarette, if you inhale more deeply, if you draw harder on the cigarette, if you take more puffs, then you change the amount that you get from it." The machine doesn't smoke like a human subject (it takes a 2-second puff, just once a minute). Why?... Because the machine doesn't crave addictive nicotine.... but people do!

Philip Morris has known that for nearly 30 years. An internal 1974 company document written by the then head of research says, "People smoke in such a way that they get much more than predicted by machine." Because "it gives low numbers," the report recommended that the FTC test should be retained and used in its advertising of "light" cigarettes. Another researcher, hired by Philip Morris in 1976 to analyze cigarette safety, reported in another internal document that low-tar cigarette smokers compensate by simply smoking more "lights" and by using additional maneuvers to get more (nicotine) out of each.

So, how does the cigarette deliver less tar to the machine and more to the smoker? 60 Minutes II noted what most smokers overlook: there are tiny holes in the filter that allow fresh air to dilute the smoke. A smoker, unlike a machine, can cover the holes with his or her fingers; put lips over them; or suck harder and get more tar than if they weren't covered. Thus, a nicotine addict can instinctively defeat the stated purpose of the holes. The FTC dramatically underestimated the ability of the tobacco companies to engineer these cigarettes so that, while they would likely deliver a full dose of tar (and the highly addictive nicotine) to people, they would provide a trivial dose to the machine. Bottom line: the tobacco industry demonstrated in their own internal studies that the light cigarettes and the regular cigarettes, when smoked by people, delivered exactly the same amount of tar and nicotine.

My advice to you, Chagrined, is to call the New Jersey Quitline (1-866 NJ-STOPS) which offers free smoking cessation counseling and advice. "Lights" are killing you.
