How Did Movies Affect Teen Smoking?

Smoking is undoubtedly a unwanted habit that should not be encouraged because it can cause smokers as well as people around them (through secondhand smoke) suffer chronic diseases including lung cancer, heart disease, stroke, COPD (chronic obstructive pulmonary) and erectile dysfunction. It can lead to birth defects, too.

Teens smoke for a number of reasons. Pressure among the peers and smoking habit of parents or relatives tend to influence the teens to follow suit. A study by the Centers for Disease Control and Prevention (CDC), however, indicated that smoking among teens is somehow related to movies with tobacco.

According to their findings that were published on July 14, 2011 in the ‘Morbidity and Mortality Weekly Report’, number of movies in the United States in which an actor smoked fell sharply between 2005 and 2010.

55 percent of movies that had huge box office grossing in the United States in 2010 did not have smoking scenes, compared with a third of films that scored huge box office success in 2005.

During the same 6-year period, the number of tobacco incidents in top-grossing movies fell by 56 percent, though there were still some 2,000 scenes where an actor used tobacco either openly, on screen, or implicitly, off-screen. In fact, the percentages of 2010 top-grossing movies with no tobacco incidents were the highest observed in 2 decades.

In 2010, a study released by CDC found that the percentage of middle school students in the United States who smoked fell from 11 percent to 5 percent between 2000 and 2009 and those who experimented with smoking fell from nearly 30 percent to 15 percent.

Meanwhile, use of other tobacco products like cigars, pipes and chewing tobacco was also down among middle school boys aged between 11 and 14. The smoking among high school students was also down though less sharply.

17 percent of high school students smoked cigarettes in 2009, comparing to 28 percent in 2000, while 3 in 10 high school students tried smoking 2 years ago, comparing to nearly 4 in 10 in 2000.

The drop in onscreen smoking might have contributed to the decline in smoking among middle school and high school students.

Do You Want Your Heart Disease Risk Doubled?

While cigarette smoking can induce numerous medical disorders to smokers themselves, people who are exposed to smokers’ tobacco smoke are also at a high risk of getting similar medical disorders. One of the disorders is heart disease, one of the leading killers in the world.

Researchers from the University College London reported that people who are around smokers and breathe in a lot of smoke are twice as likely to die from heart disease as those who are exposed to lower levels of secondhand smoke. Their study, which covered more than 13,000 people in England and Scotland, was published on June 29, 2010 in the ‘Journal of the American College of Cardiology’.

A saliva test was used to measure the amount of secondhand smoke people have been exposed to and the participants were followed for an average of 8 years, keeping track of who developed heart disease and who died.

It was found that 32 out of about 1,500 people who had never smoked but were exposed to high levels of secondhand smoke died of heart disease. In comparison, only 15 out of about 1,000 people who never smoked but with low exposure. Their analysis, which was restricted to never-smokers only, showed that high secondhand smoke exposure was linked to more than a 2-fold increased risk of dying from heart disease.

High level of exposure, according to the definition set by the researchers, would be equivalent to living with a smoker and exposed to secondhand smoke almost every day.

This is definitely not the first study to reveal such association. In a 10-year study published in 1997 in the journal ‘Circulation’, researchers from the Harvard School of Public Health reported that women who never smoked but regularly exposed to other peoples’ smoking in home or work had their risk of heart disease almost doubled.

More than 32,000 healthy women who never lighted up a cigarette were tracked. These women, aged between 36 and 61 when the study began, suffered 152 heart attacks, 25 of them fatal.

In order to prevent heart disease, smokers are urged to give up this unhealthy and selfish habit for the sake of their loved ones. Meanwhile, people staying with smokers should strive to help them quit smoking so as to lower the risk of heart disease for all in the house.

How To Help Women Quit Smoking?

Smoking is definitely not a good habit for health. Smokers are at a higher risk of getting not only lung cancer but also other diseases including heart disease and chronic obstructive pulmonary disease (COPD). More importantly, smokers can pose health risk to people around them through secondhand smoke.

While smokers are aware of the risk they face, many of them especially females are reluctant to quit because they afraid they could gain weight after they stop smoking. In fact, most smokers who quit smoking will eventually gain 5 to 15 pounds.

Researchers from the University of Pittsburgh Medical Center reported that a combination of specialized counseling and the anti-smoking drug Zyban might boost, at least for a while, chances of quitting smoking for female smokers.

Zyban is a prescription drug used to help smokers give up their habit. It comes in a pill form, and it does not contain nicotine. Hence, it is not a nicotine replacement therapy product. Zyban is the trade name of the drug called “bupropion” and it was approved in 1997 as a stop smoking aid.

The findings, appeared on March 22, 2010 in the ‘Archives of Internal Medicine’, showed that over a period of 6 months of treatment, women who received the combo therapy were more successful at quitting than those who received weight counseling only, and more successful than those who received standard smoking-cessation counseling plus Zyban.

Over the period of 6 months, 34 percent of women in the group that received weight counseling and Zyban consistently abstained, comparing to 21 percent of women who received standard counseling and Zyban, 11 percent of those who received weight counseling and placebo (inactive pills) and 10 percent of those who had standard counseling and placebo.

However, the positive effect faded after treatment ended. At the 1-year mark, 24 percent of women in the group that received weight counseling and Zyban had still remained abstinent, as compared with those in the group that received standard therapy/Zyban. Yet, researchers still insisted that cognitive behavioral therapy, which was developed by them, aimed at smokers' weight-gain issues could give certain women an extra push to quit.

If You Quit Smoking, Others Will Just Follow!

Smoking is not a desirable habit since it will not only put smokers but also place non-smokers through second smoke at higher risk of getting many diseases including cancer, heart disease, hypertension (high blood pressure), and stroke. That is why many countries around the world including China have banned smoking in the public areas.

The influence among the social network could, however, also help smokers give up smoking immediately.

According to a paper published in the May 22, 2008 edition of the ‘New England Journal of Medicine’, if a person quit smoking, then this person’s spouse, best friends, colleagues and even the surrounding people who are not known very well to this person will just follow suit.

Researchers from Harvard Medical School analyzed relationships among some 12,000 people over 3 decades and found that a steady decrease in smoking over that period occurred in clusters. So if there is a change in the zeitgeist of this social network, the whole group of people who are connected but who might not know each other all quit together.

Zeitgeist means the spirit of the times or the spirit of the age. It is the general cultural, intellectual, ethical, spiritual within a specific group, along with the general ambiance, morals, socio-cultural direction, and mood associated with an era.

Researchers reconstructed the social networks of 12,067 individuals during a period between 1971 and 2003, recording major life changes such as marriage, death and divorce.

All the study participants also listed contact information for close friends, work colleagues and neighbors. Interestingly, many of those friends and colleagues had also joined the study. This enabled the researchers to observe a total of 53,228 families, social or professional relationships. Their findings showed that people quit smoking in clusters.

Over the 30-year period, the average size of each particular cluster of smokers within the entire network remains about the same but there are fewer and fewer of these clusters left as time goes on.

How Fast Can Stroke Cause Brain Damage?

A stroke, sometimes also known as brain attack, occurs when there is an interruption of blood supply to any part of the brain because of blockage or burst in one of the blood vessels in the brain. If the brain cannot get blood and oxygen, the brain cells could die and permanent damage would be caused within a relatively short period.

Stroke is one of the top killer s in the developed countries. In Canada, stroke ranks the fourth leading cause of death, affecting as many as 50,000 people and killing 16,000 every year. Risk factors for stroke include alcoholism, diabetes, high cholesterol, overweight or obesity, physical inactivity, smoking and stress.

So how fast can stroke damage the brain?

Common public perception believes that all strokes can be medically treated within 3 hours, but scientists from the University of British Columbia in this Western Canadian city reported otherwise. Their study, which was funded by the Heart and Stroke Foundation of Canada, found that stroke could cause brain damage within 3 minutes.

Generally, stroke can be categorized into 2 types: ischemic and hemorrhagic. Ischemic strokes are those caused by interruption of the blood supply, while hemorrhagic strokes are those that result from rupture of a blood vessel or an abnormal vascular structure.

About 80 percent of stroke patients suffer ischemic stroke, which can usually be treated by clot-busting medications, provided if they could be admitted to the hospital within 3 hours. In reality, not every stroke patient is a candidate for clot-busting drugs.

Based on the results obtained from animal experiments performed, the scientists declared that brain could be damaged within 3 minutes. Such 3-minute window does not give people sufficient time to even call for help.

Preventive measures, therefore, are urgently required to tackle structural changes that happen very early on. People just need to manage risk factors and change their lifestyle to prevent getting a stroke, instead of relying on treatment when stroke strikes them.

Can Smoking Relieve Stress?

Numerous studies have shown that smoking and secondhand smoke are linked to many medical disorders including cancer, heart disease, hypertension (high blood pressure), and stroke. So quitting smoking would certainly be beneficial to both smokers and people around them.

Interestingly, many smokers have claimed that lighting up a cigarette can actually help them reduce the stress they have. This is probably a fairly good reason for millions of smokers to light up their cigarettes again even after quitting.

But studies have found otherwise. In reality, smoking has the entirely different effect. Instead of reduced, the long-term stress levels will be raised among smokers. In fact, smokers can have their stress relieved only when they quit smoking.

In a paper published on June 7, 2010 in the journal “Addiction”, researchers from the London School of Medicine and Dentistry found that smokers who stopped lighting up cigarettes had a significant larger reduction in perceived stress.

A total of 469 people, who attempted to quit smoking after being hospitalized for heart disease, were examined. At the outset, the participants had similar stress levels and about 85 percent of these people generally believed that smoking helped them cope with the stress they had.

After a year, 41 percent of the participants managed to quit smoking completely and their perceived stress levels were reduced by about 20 percent, whereas patients who continue smoking showed little change in their perceived stress levels.

Obviously, the findings supported the theory that smoking can actually contribute to stress among some people. But why do smokers still think that lighting up a cigarette could help them relieve stress?

According to researchers, when smokers are refrained from smoking, they tend to feel more and more edgy, irritable and uncomfortable as the period lengthens. A cigarette would more or less help them get through the stressful state. This is probably the main reason smokers think that smoking help them reduce stress.

Therefore, smoking can relieve stress is actually a myth, at least in the long term.
