From country to country, aging men are experiencing a problem that commonly occurs in half of the middle-aged population. While a large number of men are affected by the condition known as impotence (Erectile Dysfunction), few are willing to openly accept it. ED is an issue that can lead to clinical depression and has been reported to contribute to emotional instability.
Fortunately, with the use of scientifically enhanced medications, the consequences of impotence are a thing of the past. Men across the globe have discovered the pharmaceutical remedies that keep ED in submission. With the use of certain medications, men report that they have a fuller love life and have an increased sense of well-being. Whether information regarding a variety of drugs is researched by the man experiencing ED or his sexual partner, quality enhancements can be found at www.aptekakamagra.pl
Most adult men prefer to pursue a natural course of action before resorting to medications. While pharmaceutical enhancement pills provide immediate stimulation, there are supplements that enhance male performance such as L-Arginine and DHEA. Like prescription drugs for the improvement of male arousal, L-Arginine and DHEA are supplements that are completely legal. They can be purchased at one of the many
Electronic cigarettes, also known as e-cigarettes, have become tremendously popular in the past few years. The rise in the global industry for e-cigarettes can be chalked up to many reasons. For starters, countries across the globe have now introduced strict regulations regarding conventional cigarettes. All cigarette packets are now required to carry a warning about the harmful effects of smoking, such as the fact that it can cause cancer. Numerous awareness programmes have also been funded and initiated in order to improve the general health of the community and to make people aware of just how damaging cigarettes can be.
The e-cigarette industry has grown primarily because many people consider e-cigs to be a direct alternative for conventional smokes. Even though there aren’t any official studies confirming that e-cigs have no harmful ingredients, the biggest reason why many consider them to be a healthier alternative is because they don’t contain all of the harmful chemicals and carcinogens that you find in an ordinary cigarette. Even though most people smoke ordinary cigarettes for the nicotine and the tobacco inside, a number of other harmful chemicals are also burned whenever you puff on an ordinary smoke. An electronic cigarette
It has been described as a ‘disruptive technology’ potentially capable of breaking our fatal relationship with tobacco. So the setting for a public debate on e-cigarettes – a museum part-funded by the tobacco industry, in a city home to the global headquarters of one of the largest tobacco manufacturers – was perhaps ironic. Yet on Wednesday evening, I found myself at the M-Shed in Bristol, watching just that: a debate about whether e-cigarettes could be part of the solution to the tobacco epidemic.
To mark the launch of a new Integrative Cancer Epidemiology Programme, linked to the Medical Research Centre Integrative Epidemiology Unit at the University of Bristol, Professor Marcus Munafò (Professor of Biological Psychology at the University of Bristol) and Professor Linda Bauld (Professor of Health Policy at the University of Stirling), both collaborators of mine, discussed e-cigarettes. Professor Gabriel Scally (Public Health Doctor and former Regional Director of Public Health for the South West of England) chaired the discussion.
Billed as a debate about whether e-cigarettes might be ‘the key to reducing smoking’, some in the audience may have expected a heated discussion. However, with this line-up of academics, influential in the fields of
are battery-powered vaporizers that simulate the feeling of smoking, but without tobacco. Their use is commonly called “vaping”. The user activates the e-cigarette by taking a puff or pressing a button.Some look like traditional cigarettes, but they come in many variations. Most are reusable but there are also disposable versions called first generation cigalikes There are also second, third, and fourth generation devices. Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor. E-cigarettes typically have a heating element that atomizes a liquid solution known as e-liquid.-liquids usually contain propylene glycol, glycerin, nicotine, and flavorings.
The benefits and the health risks of e-cigarettes are uncertain. There is tentative evidence that they can help people quit smoking, but they have not been proven better than regulated medicationTheir usefulness in tobacco harm reduction is unclear, but they could form part of future strategies to decrease tobacco related death and disease.Their safety risk to users is similar to that of smokeless tobacco. Regulated nicotine replacement products are safer than e-cigarettes but e-cigarettes are probably safer than smoking.
Nicotine is associated with a range of harmful effects Non-smokers who use e-cigarettes risk nicotine
It’s become an emotional debate: Do e-cigarettes help people get off regular cigarettes or are they a new avenue for addiction?
Until now, there has been little solid evidence to back up either side. But a new study from the Centers for Disease Control and Prevention could help fill that void.
E-cigarettes work by heating up a fluid that contains the drug nicotine, producing a vapor that users inhale. The CDC found that nearly 48 percent of current tobacco smokers said they had tried e-cigarettes at least once. Among those who recently quit smoking, more than 55 percent said they’d tried the devices.
The survey of more than 36,000 U.S. adults marks the first time detailed federal data about e-cigarettes has become available, says Charlotte Schoenborn, a health statistician with the National Center for Health Statistics. The data were gathered as part of the National Health Interview Survey, an ongoing survey of a variety of health issues.
Among those still using the devices when surveyed, almost 16 percent said they were still smoking tobacco cigarettes, Schoenborn says, while 22 percent had recently quit.
The study found that the devices are most popular among
a major scientific review of research on e-cigarettes, UC San Francisco scientists found that industry claims about the devices are unsupported by the evidence to date, including claims that e-cigarettes help smokers quit.
The review marks the first comprehensive assessment of peer-reviewed published research into the relatively new phenomenon of electronic cigarettes.
The devices, which are rapidly gaining a foothold in popular culture particularly among youth, are marketed as a healthier alternative to tobacco smoking, as an effective tool to stop smoking, and as a way to circumvent smoke-free laws by allowing users to “smoke anywhere.” Often the ads stress that e-cigarettes produce only “harmless water vapor.”
But in their analysis of the marketing, health and behavioral effects of the products, which are unregulated, the UCSF scientists found that e-cigarette use is associated with significantly lower odds of quitting cigarettes. They also found that while the data are still limited, e-cigarette emissions “are not merely ‘harmless water vapor,’ as is frequently claimed, and can be a source of indoor air pollution.
The long-term biological effects of use are still unknown, the authors said.
In tackling the question of whether e-cigarette use is helping
cigarettes to be cool or rebellious, or because their friends are doing it. These days, though, the cigarettes they smoke are more and more of the electronic variety — not tobacco.
A study published earlier this month shows that middle school and high school students who smoke e-cigarettes also are more likely to smoke tobacco cigarettes. While that doesn’t mean e-cigarettes lead kids to smoke tobacco cigarettes, it does show a strong link between the two habits.
Further research shows that 70% of adult smokers start before age 18.
The growing popularity of e-cigarettes — among adults as an aid to quit smoking and among teens — has turned them into a $1.5 billion-a-year industry. Revenue could grow to $3 billion in 5 years.
Research into their potential effects on health, though, is still in the early phases. There’s enough concern that the FDA is considering regulations.
For teens who have never smoked, e-cigarettes are an introduction to nicotine, which is highly addictive. Public health officials are worried this could lead to tobacco use.
For adults who smoke tobacco cigarettes, e-cigarettes may not be as dangerous, because they don’t have the same toxins as the
“E-cigarettes are 95% less harmful than tobacco and could be prescribed on the NHS in future to help smokers quit,” BBC News reports.
This is the main finding of an evidence review (PDF, 485kb) carried out by Public Health England, a government agency that aims to protect and improve the nation’s health and wellbeing, and reduce health inequalities.
What are e-cigarettes?
Most e-cigarettes contain a battery, an atomiser and a replaceable cartridge. The cartridge contains nicotine in a solution of either propylene glycol or glycerine and water, and sometimes flavourings.
When you suck on the device, a sensor detects the air flow and starts a process to heat the liquid inside the cartridge, so it evaporates to form water vapour. Inhaling this vapour delivers a hit of nicotine straight to your lungs.
Unlike “traditional” cigarettes, they do not contain the many dangerous chemicals that can increase the risk of lung cancer, heart disease and stroke.
What are the main findings of the review?
- There has been a rise in e-cigarette use that has been matched by a corresponding decrease in smoking.
- E-cigarettes are now the most popular quitting aid in England.
- There is good-quality evidence that e-cigarettes
Sales of electronic cigarettes have fallen sharply in recent months, bringing an end to five years of triple-digit growth and making the much-touted category look more like a potential fad than real threat to Big Tobacco.
Growing dissatisfaction among customers, inventory backlogs, new state laws and rising safety concerns are expected to cut the rate of e-cigarette growth in half next year to 57% from its compound annual growth rate of 114% over the past five years, according to the research firm Euromonitor International. Because of the rapid sales declines, Euromonitor research analyst Eric Penicka said he is preparing to “pull back that forecast” even further.
The slowdown has been most noticeable among Big Tobacco’s “cigalike” devices, which look like cigarettes. Sales of those fell 21% and volume dropped 11% during the 12-week period ended Oct. 31, marking the first quarterly decline in sales and volume, according to Nielsen data cited by Wells Fargo.
Reynolds American Inc., the nation’s second-largest tobacco company behind Altria Group Inc., said in September that it would post $100 million in asset write-downs and exit charges to consolidate its e-cig manufacturing. In July, Reynolds told investors it
Two weeks ago, I received an email from NJOY, a company that sells electronic cigarettes. Its purpose was to introduce the Daily, a new product that NJOY described as “a superior e-cigarette scientifically developed to deliver quick-and-strong nicotine satisfaction at levels close to an actual cigarette.”
One reason many adult smokers haven’t switched to e-cigarettes is that most e-cigarettes don’t provide the same nicotine kick as a real cigarette. With some 42 million American adults still smoking, and 480,000 of them dying each year as a result, this is tragic. Though nicotine is addictive, it is the tobacco that kills.
An e-cigarette that could truly replicate the experience of smoking would dramatically reduce — not eliminate, but reduce — the dangers of smoking. NJOY claims that the Daily comes closer to that experience than anything on the market. When I spoke to Paul Sturman, NJOY’s chief executive, he emphasized not only the nicotine aspect, but also the Daily’s “feel,” and “the intensity of the hit to the back of the throat.”
A British government agency has issued a bullish assessment of the value of electronic cigarettes in helping people to quit smoking. It found that e-cigarettes can reduce the health risks of smoking by 95 percent because they deliver nicotine to satisfy an addiction, but far fewer harmful chemicals than regular cigarettes. It also found little evidence that large numbers of consumers who had never smoked were taking up e-cigarettes. That seemed to challenge the notion that e-cigarettes would be a gateway to more dangerous products.
But the study is hardly definitive; experts in America have drawn different conclusions on usage and on the gateway issue.
The British assessment, commissioned by Public Health England and conducted by academic experts, was cautious in its claims. It noted that the best results are obtained when e-cigarettes are used in combination with professional counseling and smoking-cessation medication.
In the United States, according to the Campaign for Tobacco-Free Kids, e-cigarette use by young people has grown more rapidly than in Britain. The user population includes many children who have never smoked
You may have seen electronic cigarettes (e-cigarettes) in stores, in advertisements, or being used. But e-cigarettes, while increasingly popular, are not harmless. Created as an alternative to tobacco cigarettes, e-cigarettes are sophisticated mechanical devices designed to deliver the same highly addictive nicotine that is in tobacco cigarettes, without the other harmful effects of tobacco smoke.
In the past decade, e-cigarettes have become a more than $1 billion industry in the United States, with over 460 brands on the market. Many adults who use e-cigarettes are current or former smokers looking to stop nicotine cravings, quit smoking, or cut down on tobacco cigarettes. However, e-cigarettes may have a limited effect on helping people quit since at least 75 percent of adults who use e-cigarettes also use tobacco cigarettes.1
And although most states prohibit the sale of e-cigarettes to people under the age of 18, more and more teens are using them. In fact, recent surveys2 show dramatic increases each year in the number of teens who have tried an e-cigarette in their lifetime, as well as in the number who have used them in the past month. This is at a time when smoking tobacco
The National Park Service announced Monday that electronic cigarette use is now banned anywhere smoking is prohibited on its vast and far-flung landholdings, despite unsettled science on possible health effects from secondhand vapor inhalation and what’s likely a minimal fire risk.
National Park Service Director Jonathan Jarvis publicly announced the new policy in a press release, describing it as a step to safeguard people’s health – fighting words for advocates of the devices, which vaporize liquid that’s generally laced with nicotine.
“Protecting the health and safety of our visitors and employees is one of the most critical duties of the National Park Service,” Jarvis said. “We are therefore extending the restrictions currently in place protecting visitors and employees from exposure to tobacco smoke to include exposure to vapor from electronic smoking devices.”
Park Service employees were alerted to the policy last week in a memo that cites disputed findings about e-cigarettes emitting formaldehyde and a toxic chemical also found in antifreeze
The memo says the decision was taken “out of an abundance of caution in light of the scientific findings and uncertainty to date, and in the interest of equity.” It amends a 2003 policy document – last
In the near future, all 1.2 million American households residing in public housing units may be banned from smoking tobacco indoors – but the now-commonplace proposed regulation is inflaming passions, with the Department of Housing and Urban Development threatening to include e-cigarettes in the ban.
The department explicitly requested input Thursday about whether to include the vapor-producing devices when it issues a final regulatory rule sometime after a 60-day public comment period, and familiar battle lines already are drawn.
The American Lung Association and the Campaign for Tobacco-Free Kids say e-cigarette use should be banned by HUD even if the devices are less harmful than their known cancer-cousin relatives, as they emit nicotine, pose a small fire risk and emit particles into the air.
On the other side are consumer advocates and e-cigarette trade groups, who say including the devices in smoking bans would discourage people from transitioning from cigarettes to a likely less harmful alternative
“Vapor products create no smoke and leave behind no lingering smell, so outside of hiring peeping Toms, there is simply no way to enforce such a ban,” scoffs Gregory Conley, president of the American Vaping Association trade group.
Julie Woessner, executive director of the Consumer Advocates for Smoke-free
Electronic cigarettes, or e-cigarettes, are a popular new tobacco product that have still largely unknown public and individual health effects. In fact, you may be surprised to learn that e-cigarettes are entirely unregulated by the U.S. Food and Drug Administration (FDA). Because of this, there are no safety checks or requirements for what can go into an e-cigarette.
The American Lung Association is concerned about the potential health consequences of e-cigarettes. Federal oversight and regulation of e-cigarettes is desperately needed to protect children and the public. This need becomes more urgent as e-cigarette use dramatically increases, especially among youth.
What Are E-cigarettes?
» 5 Myths and Facts about E-cigarettes
E-cigarettes, including e-pens, e-pipes, e-hookah and e-cigars, are known collectively as electronic nicotine delivery systems (ENDS). According to the FDA, e-cigarettes are devices that allow users to inhale an aerosol (vapor) containing nicotine or other substances.
Unlike traditional cigarettes, e-cigarettes generally are battery-operated and use a heating element to heat e-liquid from a refillable cartridge, releasing a chemical-filled aerosol.
What Is in E-cigarettes?
The main component of e-cigarettes is the e-liquid contained in cartridges. To create an e-liquid, nicotine is extracted
f you think e-cigs are a safer alternative to regular cigarettes, think again.
An independent study from the Center for Environmental Health (CEH) this week has offered new evidence that e-cigarettes contain cancer-causing agents. If the research holds up, the devices’ days as a “healthy alternative to smoking” may be numbered.
The e-cigarettes used today are based on one a Chinese pharmacist named Hon Lik created in 2003. Lik made the device with the hopes of kicking his smoking habit—one that he had just watched take his father through lung cancer. While it didn’t help Lik quit, it did pique the interest of those around him.
After first taking off online, the device made its way to Europe and the U.S. between 2006-2007. By 2009 an estimated 100,000 had been sold in America. After a few big name celebrities like Leonardo DiCaprio were pictured with one, the device took off.
Today, experts estimate that more than 20 million Americans have tried e-cigarettes, bringing sales of the product above $3 billion dollars annually. Investment analysts say the industry is on the verge of a rapid expansion, with the potential of reaching $10 billion in the
Women exposed to first- and secondhand tobacco smoke may be at greater risk for infertility and earlier menopause, according to new research.
Active and passive smoking were found to increase women’s risk of infertility and earlier menopause in the latest study.
Study coauthor Andrew Hyland, of the Roswell Park Cancer Institute in Buffalo, NY, and colleagues publish their findings in the journal Tobacco Control.
It is well established that smoking can increase the risk of lung cancer, stroke and heart disease, among numerous other health problems.
Previous research has also associated tobacco use with infertility and earlier menopause in women. However, Hyland and colleagues note that it was unclear whether secondhand smoke exposure poses the same risks.
To find out, the team analyzed the tobacco exposure of 93,676 women aged 50-79 who were part of the Women’s Health Initiative Observational Study (WHI OS). All women were enrolled to the study between 1993-1998.
Women who were current or former smokers were asked the age at which they started smoking, how many years they had smoked and how many cigarettes they smoked daily.
Women who had never smoked were asked whether
opular belief holds that e-cigarettes are a safer alternative to conventional smoking. But increasingly, researchers are uncovering the negative impacts the electronic devices may have on health. Now, a new study has identified chemicals in the vapor of two popular e-cigarette brands that can damage cells in a way that could cause cancer.
Co-lead study author Dr. Jessica Wang-Rodriquez, professor of pathology at the University of California-San Diego, and colleagues publish their findings in the journal Oral Oncology.
Use of e-cigarettes (electronic cigarettes) has become popular in the US; a recent study from the Centers for Disease Control and Prevention (CDC) found that almost 13% of Americans have tried e-cigarettes at least once in their lifetime, with more than a fifth of adults aged 18-24 having used the devices.
While e-cigarettes do not contain tobacco – like conventional cigarettes – the vapor produced by the device and inhaled by users does contain nicotine flavorings and other chemicals. Nicotine is the chemical that makes smoking addictive.
How such chemicals impact human health has been a hot topic in recent years; while some studies have suggested e-cigarettes are significantly less harmful than standard cigarettes and can
