Trying to quit smoking? Or, at least, thinking for trying to give up?
You may have more luck with e-cigarettes than nicotine patches or gum, according to a new study published today in the New England Journal of Medicine.
A clinical trial involving some 900 smokers in the UK found that 18 percent of e-cigarette users were smoked for one year, compared with 9.9 percent of people who used nicotine replacement products, such as patches, tires chewing, spraying.
Lead researcher Peter Hike of Queen Mary University in London said that although e-cigarettes were most commonly used in attempts to prevent smoking, there was not much evidence to help them.
During the trial, participants received either a three-month supply of a nicotine replacement product (or a combination of products), or an e-cigarette packet bag with one or two e-bottles, and encouragement to purchase future purchases.
For at least four weeks of the trial, the participants also received weekly support from one to one behavior.
Among those who successfully ceded, 80 percent of e-cigarette users were still in the aftermath of a year, but only 9 percent of those who gave nicotine replacement products were still using them.
Co-author of the study, Hayden McBrove, said that while the risks of long-term departure were not known, "wearing smoking [was] far the biggest risk ".
"We want to see smokers switch [to vaping], and then in the ideal sense, "said Professor McBroby, a professor of public health interventions at the Queen Mary University in London.
"But for people who do not smoke, we do not want to start running."
More effective than leaving the cold turkey
Coral Gartner, who heads the Nicotine and Tobacco Regulatory Research Group at the University of Queensland, said the findings provided "high-level evidence" of the use of e-cigarettes as a way to quit smoking.
"This study provides quite good support for that [e-cigarettes] are an approach that we could use in clinical practice, "says Dr. Gartner, who was not involved in the study.
She said the dropout rates in the study – 18 per cent for e-cigarettes and 9.9 per cent for nicotine replacement therapy – were significantly higher than the average cold turkey success rate.
"So, I will see the outcome of an e-cigarette – 18 percent – as very good, because of the low success rate of the necessary abandonment."
According to researchers, the "stronger effects" of e-cigarettes found in the study (compared with previous trials) may be due to the involvement of smokers who are actively seeking help, providing face-to-face support and the use of modern, recurrent e-cigarettes .
"It was not," Here's an e-cigarette, good luck! "- people had support in their behavior along with it," said Professor McBrove.
"Participants were dependent smokers, but they were also people who wanted to give up.
"I think the study shows that e-cigarettes can help you quit smoking, but they are not a magical cure … there are other things that need to be done to make this journey easier."
Regarding the reasons why e-cigarettes were more effective than other nicotine replacement products, the researchers suggested that giving birth would allow people to better adjust the nicotine dose and provide some of the known cigarette smoking behaviors.
"E-cigarettes were more effective in relieving the symptoms of withdrawal of tobacco … and were judged to be more favorable to refrain from smoking nicotine replacement products," they write.
According to the study, further investigations are needed to determine if the results could be generalized outside of UK anti-smoking services.
Concern for long-term use
While abstinence rates were higher among e-cigarette users at all points during the trial, the rate of continuous use of theft at the end of the 12 months was "quite high" – eight out of 10 users were still votes.
"This can be considered problematic if the use of e-cigarettes for a year encourages long-term use, which may present even unknown health risks," the authors write.
This is one of the key concerns of Australia's public health experts: there is insufficient evidence to show victory is safe, especially in the long run.
Simon Chapman, a professor of public health at the University of Sydney, recently told ABC: "It will take decades before we know whether or not it is not dangerous from smoking and how much, if at all."
A recent CSIRO report on the regular use of e-cigarettes is likely to have "negative health consequences", but the report also notes that there is a lack of "clarity about the size of the adverse health effects and the amount of e-cigarette use needed for a trigger [them]".
According to Dr. Gartner, there must be a "trade": accepting the long-term use of e-cigarettes for "greater success".
"Obviously, smoking or pollution is not the safest option, but if someone tries to quit smoking, it may take many years … and a bribe can help them stop and reduce their risk.
"It's about minimizing damage – helping people to move along a continuum of risk, to a lesser risk."
Dr Gartner said that it is important that people who smoked and joined together solely to trample, and when they could, completely discontinued.
"I will encourage people who use freezing – even as a way to stop smoking – they also stop coming to an end," she said.
She and Professor McRobbie said that part of the challenge was that the more frequent and longer-lasting use of extraction – as we saw in the study – is probably an "important factor" in the higher success rates of people who used to quit.
"We know that the use of long-term nicotine replacement therapy prevents recurrence, and that's probably what we see here: it's prevention of relapse," said Professor McBrove.
Dr Gartner said that although vaping was lower risk behavior, it was not risky.
"It's a complex and difficult area. It's easy to say" Stop: do not use anything. "But that's the same with many health behaviors – it's hard," she said.
Push for a review of the regulation
More and more, Australia stands alone when it comes to regulating e-cigarettes.
In Australia, New Zealand, the United States and Canada, the legal nicotine is legal, however, the sale of liquid nicotine is illegal in Australia – a ban that was confirmed by the Therapeutic Goods Administration (TGA) in 2017.
People who want nicotine in their e-cigarettes must order it in a foreign state or access through a doctor's prescription. But many doctors are ready to prescribe.
"E-cigarettes containing nicotine are not available to current Australian smokers, as there are no products that are approved as aids to stop smoking," said Dr. Gartner.
In Australia, all smoking quit products must be formally assessed and approved by the TGA.
"Unless something has changed radically, at this stage it's basically a deadlock … it's not much of a concern to get a product approved by them," said Dr. Gartner.
She said that instead of curative regulations, policymakers should "look very seriously on different models", including the creation of nicotine-containing e-cigarettes available as a consumer product in a "highly regulated manner" with "many controls."
"We currently have the most harmful products – tobacco cigarettes – sold in supermarkets," she said.
"We have to ask: is it really appropriate, especially when there is another product that can replace them and be part of the risk?"
Professor McBrove agreed that making smokers available to smokers, "but it does [our] best to limit the smokers "was" ideal ".
"It's about finding that balance," he said.
Public health experts have expressed concerns about the potential exploitation of young people – and this provides a tobacco-smoking portal – if regulation is to be changed.
In September, the US Food and Drug Administration announced that it is considering banning elegant cigarettes with taste, while the country is struggling with the "epidemic" of e-cigarette use by young people, which threatens to create a new generation of nicotine addicts.
The Dr said it was "definite concern" and some health authorities would need to "closely monitor".
"I do not think that we should always assume that if we want to change the way e-cigarettes are regulated, we will see the model they saw in the United States," she said.
"But that's something that we should be watching and trying to minimize as much as possible."
