Cigarettes Cut About 10 Years Off Life, 50-Year Study Shows By Marc Kaufman Fifty years after British researchers published the first study firmly linking cigarette smoking to lung cancer, the same scientist following the same group of British doctors has reported the most detailed and long-term results ever of the health effects of smoking. His stark conclusion: A life of cigarette smoking will be, on average, 10 years shorter than a life without it. While the lethal effects of cigarette smoking have long been known, the new study, published yesterday in the British Medical Journal, is the first to quantify the damage over the lifetime of a generation. The effects, the researchers reported, were "much larger than had previously been suspected." In the 50-year study of a group of almost 35,000 British doctors, the pioneering epidemiologist Richard Doll, who is now 91, and his colleagues found that almost half of all persistent cigarette smokers were killed by their habit, and a quarter died before age 70. The study also found, however, that kicking the cigarette habit had equally dramatic effects. He found, for instance, that someone who stops smoking by age 30 has the same average life expectancy as a nonsmoker, and someone who stops at 50 will lose four, rather than 10, years of life. "What we now know is that consistent cigarette smoking doubles mortality rates in both middle age and old age," said Richard Peto, Doll's 30-year associate in the ongoing study. "But we also know that stopping smoking will significantly limit the harm." The consequence of the tobacco "epidemic" has been to undercut great strides in public health that would otherwise have kept millions more people alive, the researchers said. "Over the past few decades, prevention and better treatment of disease have halved nonsmoker death rates in Britain," said Doll, lead author on both the 1954 and current tobacco studies. "But these improvements have been completely nullified by the r |

the rapidly increasing hazards of tobacco for those who continue to smoke cigarettes." Doll began studying smoking among British doctors in 1951, and the research has continued every decade since, with the final study begun in 2001. At that time, almost 6,000 of the doctors first studied in 1951 were still alive. The effects of smoking show up especially starkly after age 60. At 70, the study found, 88 percent of nonsmokers were still alive, compared with 71 percent of smokers. And at age 80, 65 percent of nonsmokers were alive but only 32 percent of smokers were. To look at the data another way, a 70-year-old who never smoked has a 33 percent probability of living to 90. For a 70-year old smoker, the probability of living 20 more years is only 7 percent. The researchers also found that a subset of British doctors, born around 1920, died of tobacco-related illnesses at a much higher rate than others -- accounting for almost two-thirds of all deaths. The researchers report that the men, who were young soldiers during World War II, smoked more because they could buy low-cost cigarettes from the government during the war and became more addicted to tobacco. Doll and Peto said that while the harm of smoking is dramatic, so is the benefit from quitting. According to their findings, a person who stops smoking at 60 will have a life expectancy three years longer than someone who continues; a 40-year-old will have a life expectancy nine years longer; and a 30-year-old will have a life expectancy no different from that of a nonsmoker. Peto said that in 1951, about 77 percent of the doctors in the study smoked -- a percentage just below the national average of 80 percent of adults. Today, Peto said, the United Kingdom has the lowest cigarette smoking rate in the developed world, about 20 percent of adults. It was unknown, however, how many of the doctors still smoked. Yesterday's results were published in the same journal exactly 50 years after the initial study appeared. Also |

yesterday, the Proceedings of the Natural Academy of Sciences published a study done at the Boston University School of Medicine that may explain why some but not all former smokers remain at high risk for lung cancer. The researchers found that cigarette smoking changes the pattern of genes expressed in lung cells, and that the changes return to normal in some people who stop smoking, but not in others. Avrum Spira and colleagues found that 97 bronchial cell genes were expressed differently in smokers than in people who had never smoked. Some of those changes increased the expression of genes that can lead to cancer growth, and other changes decreased the expression of suppressor genes that keep cancers at bay. Former smokers who had stopped at least two years before the study generally had gene patterns similar to those seen in nonsmokers, while those who quit more recently had gene patterns that resembled those of current smokers. |

Do you think anyone will read / be shocked by this? |

thoughest. |

make a long story short... on average, if you stop smoking before 30, its likely that your life expectancy will be the same as a non-smoker. |
||||||||
|
|

|
|
no, Im saying that its just good news for people who smoked, but quit at an early age. |

Shit! That's actually not as bad as I thought. I might just start again and quit when I'm 30.. |

i'm 28 and i am just starting smoking because it makes me feel cool. |

If I had to get my arse out of bed and work for a living I'd definetly be smoking! My distant memories of employment, I think the thought of a cigarette every 3 hours was what kept me going - All those weeks.. |

This topic ROCKS! I gave up smoking 2 months ago and I'm 31...... so i get to live 10 years longer than I would have! (give or take 12 months)............. now, what about smoking the weed? Any stats on that? |
||||||||
|
|
|||||||||
| |||||||||
|
|
Meh, my grandmother smoked from 14 until her death of lung cancer at 83. Seems long enough. |
||||||||
|
|
|||||||||
| |||||||||
|
|
ive stopped at 25 :) heres hoping it was soon enough! |
||||||||
|
|

These "researches" are completely arbitrary. Just statistics in a disclosed setting without having any scientifically based axioms. |

Hippy |

|

I have no idea how I quit. I was so fucking addicted. Loved it. |
||||||||
|
|
|||||||||
| |||||||||
|
|
I've never smoked in my life. so if I start at thirty, will that stop time? |
||||||||
|
|
|||||||||
| |||||||||
|
|
this is old news which seems to have been revamped for the media controlled governments wishes i suspect. you can have the last 10 years of my life if you want, that diaper wearing stuck in a home with nothing to do and no-one to talk to years. ahh bliss. if you don't smoke i suggest you start now before its too late and you get run over by a bus. |
||||||||
|
|

| |||||||||
|
|
..if I get run over by bus it doesn't matter either way. |
||||||||
|
|
|||||||||
| |||||||||
|
|
that's always a great argument anyway. I'd love to hear what you say when you lie dying and wheezing on all kinds of respiratory machines (with noone to talk to).. "I'm going to die..!! RESULT!!" |
||||||||
|
|
|||||||||
| |||||||||
|
|
It's more probable that you will instantly die from a stroke or heart arrest. Lung cancer is way below in percentage. |
||||||||
|
|
|||||||||
| |||||||||
|
|
if im going to die anyway some pain on my deathbed will be of little significance |
||||||||
|
|
|||||||||
| |||||||||
|
|
i'm so good lookin' |
||||||||
|
|
|||||||||
| |||||||||
|
|
Wish for a stroke then. No pain if it's massive. |
||||||||
|
|
|||||||||
| |||||||||
|
|
again, I wonder what you'll say when it's actually happening. |
||||||||
|
|
|||||||||
| |||||||||
|
|
just to be fair, i think for those of us who don't smoke should get an extra ten years for quitting, let's say, fingernail biting, by 30. |
||||||||
|
|
|||||||||
| |||||||||
|
|
fck that, when they pluck my stinking rotting carcass from a bloody mess i hope my organs look like pate, and if smokin gets me a foot in the grave, well theres no place like home... |
||||||||
|
|
|||||||||
| |||||||||
|
|
this just causes more and more fear people value human life to much these days what's living longer going to do for you anyways? just get on with it. i don't give a damn if smoking cuts off 10 years of my life what the fuck man! jesus christ i really hate the latest trend with living longer |
||||||||
|
|
|||||||||
| |||||||||
|
|
the less we know about "facts of life" the better. get on with it. i don't see to many people truly enjoying their long and healthy life. |
||||||||
|
|
|||||||||
| |||||||||
|
|
what about when its a cold day? and you can see your breath? . . . . . . thats the only smoking i've ever been addicted too... I guess that means I'm not 'cool' ey? |
||||||||
|
|
|||||||||
| |||||||||
|
|
i never smoked and hope that i never will. |
||||||||
|
|
|||||||||
| |||||||||
|
|
"...the lattest trend at living longer" hasn't it always be like that: humans trying to live longer...? does the word life rings a bell for you? |
||||||||
|
|
|||||||||
| |||||||||
|
|
You know that was my plan to stop smoking by 30 .... w00t!!! well I've layed off on smoking both ciggarettes, the boyfriend isnt fond of the smoking...so whatever im slowing down :D |
||||||||
|
|
|||||||||
| |||||||||
|
|
i smoke very inconsitantly and i have for about 2 years (i'm 18). I've VERY rarely smoked more than a pack in a week and gone many weeks without smoking at all. I quit for about four months but now I've been smoking at least a pack or two a week. blah blah blah. I think I'll be o.k. if I quit before too long. |
||||||||
|
|

| |||||||||
|
|
zeus: have you been succesful with quitting yet? |
||||||||
|
|
|||||||||
| |||||||||
|

a long range of thinking which dismisses western religion. and so say all of us. persistently we have had the case of a challenge between the science of 'having' to live longer and the fact that we all die at some point. at some crossroads we need to understand that the two points of view are mutually exlusive and cannot be resolved. it is up to us ans a mass of individuals to come to some common consensus and understand that a scientific and artistic view do not and ever will not intervene with each other. 2 points of view, both are valid, and both contradict each other absolutely. doomed puppy, where are you? ;) |
