Progress has been made in cutting nicotine risks, but exposure remains problem for nonsmokers
Nearly half of America’s non smokers are sucking in fumes from tobacco products. And that’s the good news!
A new study from the Centers for Disease Control showed that 46 percent of nonsmokers had signs of nicotine in their bodies during blood tests conducted between 1999 and 2004. That is down significantly from 84 percent when similar tests were conducted in the late 1980s and early 1990s.
But CDC researchers emphasize that this is no reason for celebration — not with statistics showing that exposure to secondhand smoke increases nonsmoking adults’ risk of lung cancer by at least 20 percent and their odds of heart disease by at least 25 percent.
“It’s still too high,” research Cynthia Marano told The Associated Press. “There is no safe level of exposure.”
Moreover, there was little change regarding the exposure of children ages 4 to 11 to secondhand smoke. That percentage stands at 60 percent, and CDC officials note this greatly increases children’s chances of respiratory illnesses and ear problems. In babies, the possibility of sudden infant death syndrome also increases.
Officials attributed the overall decline in the exposure rate of nonsmokers to the growing number of laws banning smoking workplaces, bars, restaurants and other public settings.
The CDC study’s findings justify the public indoor smoking legislation that will go into effect in September in Pennsylvania, virtually nullifying the argument that these bans usurp proprietors’ and individuals’ rights. Indoor smoking creates a public health issue for others and contributes to rising health care and insurance costs for everyone.
It’s good to see at least some progress being made, but to paraphrase that old cigarette commercial, “we’ve come a long way, but we have a long way to go.”

Smoking bad for you inside and out
The cosmetics sector undoubtedly cashes in on our desire to look good. We spend large amounts of money on creams and different products to enhance or maintain our appearance.
However we often fail to remember how much what we consume affects us. Cigarettes, which are universally acknowledged to take a toll on our lungs, are an item that can hinder our appearance as well. Whether we are simply social smokers or chain smokers, we may be doing damage to more than our lungs.
Recent research carried out by dermatologists has shown that people addicted to smoking cigarettes have around five times as many wrinkles as those who do not indulge in the habit. Experts, noting that some studies have even proven that cigarettes yield a stronger effect than sunrays, say: “If you don’t want to experience early aging, quit smoking!”
Dull, wrinkled, dirty-gray skin, recognized by many as being “smokers’ skin,” is a phenomenon experienced by 79 percent of smokers, says Dr. Bayram Börekçi, a skin and venereal diseases expert. He explains; “Some of the symptoms we see on smokers’ faces include permanent lines and wrinkles, as well as a collapsed facial expression resulting from the protruding bones underneath the skin.
We also see thinning skin, a light-gray appearance, as well as a light orange/purple/red coloring. The ‘cigarette addict’s face’ is the same face seen on women over the age of 70. It is worth noting that people addicted to cigarettes start getting wrinkles very early. The amount of wrinkling is parallel to the number of cigarettes smoked over the course of a year.
Some of the factors which lead to the formation of wrinkles on the skin as a result of cigarette smoking are the widening veins due to the stimulation of the nervous system by nicotine, the reduction of oxygen in soft tissues, the increase in clotting and the reduction of collagen.”
Börekçi, mentioning the toxic, mechanical and genetic effects of smoking, notes that the reduction of moisture in smokers’ skin is connected with the toxic effect of cigarettes. The doctor also notes that the wrinkling seen around the lips of some smokers is a result of the “mechanic” effects of cigarette smoking, the muscles used when actually inhaling smoke.
He notes: “Many people believe that there are also genetic factors at play here, as not all cigarette smokers have a ‘cigarette addict’s face.’ The elasticity layer in the parts of bodies which are not regularly exposed to the sun in cigarette smokers are, when compared to the same areas of the body in non-smokers, much thicker and more fragmented. The chronic reduction of oxygen to the skin also reduces the synthesis of collagen, making visible wrinkles emerge.”
He went on: “Cigarettes can cause a variety of anti-estrogen effects, such as infertility, early menopause and menstrual irregularities. The physiological effects and importance of estrogen to the skin can be seen clearly in the post-menopausal period. In women who are addicted to cigarettes, the hypo-estrogen situation that is brought about shows itself in dry skin and wrinkles. Cigarettes reduce the levels of vitamin A in the body, which means that the cells have a greatly reduced level of protection against their number-one enemy, free radicals. This too makes it easier for wrinkles to appear.

The sooner you quit, the better it is
Both of this year’s presidential candidates say they are ex-smokers, but recent research suggests that they may face increased health risks from cigarettes for years to come.
Some of the damage that cigarettes inflict on the body subsides quickly, halving the risk of heart disease and stroke within five years after a smoker quits. But the effect of smoking on risks of cancer and other diseases can persist for decades, experts say.
Even Sen. John McCain (R-Ariz.), 71, who quit smoking in 1980, still faces some increased risk of cancer from smoking two packs a day for 25 years, studies suggest. Sen. Barack Obama (D-Ill.), 46, who says he has struggled to stay off cigarettes since quitting last year, may have less long-term risk because he smoked fewer cigarettes per day.
Better to quit young
A major message of the research is that people who quit at a young age are far better off than those who put it off until later. Obama and McCain, both of whom waited until their mid-40s to quit, would have been measurably better off if they had stopped a decade sooner, experts said.
“If you quit by age 35, by the time you’re 45 you look pretty much like a never-smoker in most of our profiles of risk,” said Terry Pechacek, associate director for science at the federal Centers for Disease Control and Prevention’s office on smoking and health.
The danger intensifies as smokers approach their 30th year of addiction, Pechacek said. The risk of getting lung cancer for a person who has smoked for 30 years can be six times greater than the risk for someone who has smoked for 20 years.
Some of smoking’s effects may be irreversible. For example, the chronic bronchitis that many smokers develop heals only partially. And quitting cigarettes often has little effect on emphysema, which stems from the damage that cigarette smoke can cause in the lung’s fine structures.
“That stuff doesn’t repair itself,” said Dr. Norman Edelman, chief medical officer for the American Lung Association.
Getting other risks down to normal can take time. A study published last month in the Journal of the American Medical Association found that among women who smoked for 20 years on average, it took 30 years after quitting for their risk of lung cancer to reach normal levels.
Yet heart disease risks declined much more rapidly, the study found. Within five years of quitting, the excess risk from smoking had fallen by 61 percent.
“Clearly there are immediate benefits for some diseases,” said study co-author Stacey Kenfield, a researcher at the Harvard School of Public Health. “It’s never too late to stop.”
Cancer risks are more difficult to get back to normal because of how that disease progresses in the body, experts said.

Smoking ban ’saved 75,000 lives’
Banning smoking in bars and restaurants has saved the lives of more than 75,000 Kiwis, the Health Ministry says. Since the introduction of the legislation in December 2004, there are now 150,000 fewer smokers - bringing the total smoking population down to less than 20 per cent.
Ministry national director of tobacco control Ashley Bloomfield said half of the smokers who had quit in the past three-and-a-half years would have died as a result of their smoking.
“Those smokers who die from a smoking-related illness lose of average 15 years of life compared to non-smokers,” said Dr Bloomfield.
But Hospitality Association chief executive Bruce Robertson is disputing that where there is smoke there is fire - saying most New Zealanders would look at the statistics and think: “Really?”
Mr Robertson, whose organisation represents the bar industry, said the 75,000 figure had “little credibility” and it was hard to establish such outcomes from “very small surveys”.
He said the industry had worked hard to make the new rules work.
Dr Bloomfield said cigarette consumption had halved in the past 18 years, to around 1000 cigarettes per adult each year, down from a high of around 2000 cigarettes in 1990.

Let’s not waste another 12 years
The federal government regulates everything from breakfast cereal and hair dye to horse feed and breast implants. The list of items regulated by our government includes just about every consumable product in America from prescription drugs to vegetables.
But there’s one item strangely absent from the list, the one that causes more preventable deaths than any other product. A powerful and well-funded lobby has managed to keep tobacco off the list of federally regulated products for more than 40 years after the first surgeon general’s report linked smoking to cancer. Even today, a simple list of ingredients is not required for tobacco products.
Tobacco companies have taken advantage of this lack of oversight and have shamelessly marketed to underaged recruits through cartoon advertising, nicotine and ingredient manipulation, fruity flavors, free giveaways at rock concerts, and ads in publications with high teen readership.
In 1996, the Food and Drug Administration assumed the authority to regulate tobacco as a consumable product and published rules regarding this regulation. Some basic common-sense approaches were proposed in those rules, including ways to prohibit the sale and marketing of tobacco to children. However, the Supreme Court ruled that only Congress could give the FDA authority to regulate tobacco.
Twelve years later, we continue to wait for Congress to take action regarding this lone unregulated product. We submit to you that this is 12 years too long.
Currently being considered by Congress, the Family Smoking Prevention and Control Act, S. 625 and H.R. 1108, would give the U.S. Food and Drug Administration the authority to regulate tobacco products the way drugs, devices, and foods are currently regulated.
