This past summer, a man in the business of helping smokers quit, was diagnosed with inoperable lung cancer. Just months later, anti-smoking guru Allen Carr lost his battle with cancer. On November 29th, Carr died at his home in Malaga, Spain.

A heavy smoker for 33 years before quitting 23 years ago, Carr claimed to have found an easy way to quit smoking. From that discovery, he founded The Easy Way to Stop Smoking Program, which would eventually grow into 70 clinics in 30 countries. In addition, his company publishes how-to quit smoking books, CDs, tapes and DVDs.

Using cognitive therapy, Carr told smokers interested in quitting that they could do it without willpower, without suffering withdrawal and without gaining weight. The celebrity endorsements for his program include Sir Anthony Hopkins, Sean Bean, Marie Helvin, Johnny Cash, George Harrison, Lisa Stansfield, Sir Richard Branson, Britney Spears, Susannah York, Bruce Oldfield, Stefano Gabbana and Julie Christie.

Carr is credited with helping over 25 million people to quit smoking.

An Easy Way to Stop Smoking Program clinic spokesperson was quoted as saying, "Allen spent many years in smoke-filled rooms after he quit, while treating smokers for addiction. He is certain that had he not quit, he would have died 20 years ago." Near the time of his death, Carr wrote a letter to Tony Blair urging his government and NHS to accept the easy method program. Carr was 72.

While public and private groups, along with researchers and a few drug companies, have been making serious efforts to help smokers quit smoking cigarettes, the tobacco industry has been spiking the level of nicotine in cigarettes, according to a study by the Department of Public Health. Between the years 1998 to 2004, the amount of nicotine in cigarettes has risen by ten percent.

According to Lois Keithly , director of the Massachusetts Tobacco Control Program, "We in public health have tried to spend a lot of time figuring out why people don't stop smoking."

Full withdrawal will be felt after the first day of not smoking. But symptoms from nicotine withdrawal are felt within the first 30 minutes after the last cigarette, with smokers reporting cravings within the first hour after the last cigarette. In one hour, smokers reported anger. In three hours of smoking cessation, smokers reported heightened levels of anxiety, sadness and difficulty concentrating. Nicotine is what makes cigarettes so addictive.

The Boston Globe reports when contacted, representatives of the three major tobacco makers in the US declined to comment on the study and would not answer questions about the nicotine content of their products.

ABC World News Tonight partnered with the Centers for Disease Control and Prevention, the National Cancer Institute and the North American Quitline Consortium to present a special series Quit to Live. According to statistics, approximately 440,000 Americans will die from smoking-related illnesses this year. A more encouraging statistic is while there are 46 million smokers, for the first time, there are more ex-smokers than smokers.

Pfizer announced that Chantix (varenicline), a drug designed to help smokers quit smoking, is now available in US pharmacies. This is the first new prescription drug for smoking cessation treatment approved by the U.S. Food and Drug Administration (FDA) in a decade. When prescribed Chantix, smokers will be offered a chance to participate in a behavioral modification program called GETQUIT Support Plan at no extra cost.

Chantix acts on the areas of the brain affected by nicotine and helps those who smoke cigarettes to quit smoking in two ways: by providing some nicotine effects to ease the withdrawal symptoms and by blocking the effects of nicotine from cigarettes if they start smoking again. There is no magic bullet here, although in clinical trials the drug quadrupled the chances of a smoker quitting and was shown to be twice as effective as the currently prescribed drug Zyban.

Pfizer Helpful Answers has a program available for people without prescription coverage. People with low incomes may even qualify for free medications. For more information about Chantix and the free GETQUIT program, visit the Chantix website.

A man in the business of helping smokers quit, has been diagnosed with lung cancer. Allen Carr, who was a heavy smoker for 33 years, found what he claimed was an easy way to quit smoking after he quit smoking 23 years ago. Using cognitive therapy, Carr told smokers interested in quitting that they could do it without willpower, without suffering withdrawal and without gaining weight. The celebrity endorsements include Sir Anthony Hopkins, Sean Bean, Marie Helvin, Johnny Cash, George Harrison, Lisa Stansfield, Sir Richard Branson, Susannah York, Bruce Oldfield, Stefano Gabbana and Julie Christie.

Carr believes his lung cancer diagnosis might be the result of second-hand smoke after spending the last 23 years in the presence of his clients who signed up for his Easy Way to Stop Smoking program.

On being diagnosed with lung cancer, Carr was quoted as saying, "I have been the happiest man in the world since I stopped smoking 23 years ago and I still feel the same way. This has come as a shock but I remain very upbeat."

In addition to his quit smoking workshops, Carr wrote a book Alan Carr's Easy Way to Stop Smoking, which has sold more than 10 million copies in more than 45 countries. He claims his Easy Way to Stop Smoking method has a 53 percent success rate after 12 months compared with less than 5 percent for those who go cold turkey. Easy Way maintains a website.
