"This is the first study to show the effectiveness of e-cigarettes combined with behavioural support for giving up smoking, and the results are extremely positive," said Sophia Lowes of Britain-based charity Cancer Research UK

If you are thinking of quitting smoking, electronic cigarettes, commonly known as e-cigarettes, stand a better chance of helping you achieve your goal than nicotine replacement treatments, such as patches and gum, show results of a major clinical trial.

E-cigarettes are almost twice as effective as nicotine replacement treatments at helping smokers to quit, according to a study published in the New England Journal of Medicine.

The trial, which involved almost 900 smokers who also received additional behavioural support, found that 18 per cent of e-cigarette users were smoke-free after a year, compared to 9.9 per cent of participants who were using other nicotine replacement therapies.

“This is the first trial to test the efficacy of modern e-cigarettes in helping smokers quit. E-cigarettes were almost twice as effective as the ‘gold standard’ combination of nicotine replacement products,” said lead researcher Peter Hajek, Professor at Queen Mary University of London.

“Although a large number of smokers report that they have quit smoking successfully with the help of e-cigarettes, health professionals have been reluctant to recommend their use because of the lack of clear evidence from randomised controlled trials. This is now likely to change,” Hajek added.

The new study, which was set-up to test the long-term efficacy of newer refillable e-cigarettes compared with a range of nicotine replacement treatments, was conducted among 886 smokers who attended UK National Health Service stop smoking services.

In addition to e-cigarettes being almost twice as effective, the researchers found that e-cigarette participants reported greater decline in incidence of cough and phlegm production after 52 weeks.

But e-cigarette participants reported more throat/mouth irritation (65.4 per cent vs 50.8 per cent) and nicotine replacement participants reported more nausea (37.8 per cent vs 31.4 per cent), the results showed.

“This is the first study to show the effectiveness of e-cigarettes combined with behavioural support for giving up smoking, and the results are extremely positive,” said Sophia Lowes of Britain-based charity Cancer Research UK. (IANS)

Researchers have found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke.

The study, published in the journal Arteriosclerosis, Thrombosis and Vascular Biology, found that tobacco smoke caused blood clots to form within an average of about 11 seconds, compared to an average of five minutes for clotting without exposure to hookah smoke.

Exposure to the hookah smoke also caused other abnormalities related to the way the blood flows, the research added. Some studies have found that the smoke emitted from one hookah tobacco smoking episode contains significantly more harmful chemicals compared to a single cigarette.

“Our findings provide new evidence that hookah smoking is as unhealthy – if not more so – than traditional cigarettes. “Smoking a hookah, cigarettes, e-cigarettes or other forms of tobacco all increase your risk for heart disease and stroke,” said study researcher Fadi Khasawneh from University of Texas in the US.

In this study, researchers exposed mice to smoke from a smoking hookah’s machine that mimicked real-life smoking habits.

The smoking machine used 12 grams of commercially available, flavoured tobacco that included tobacco, glycerin, molasses and natural flavour with nicotine and tar. Researchers then compared platelet activity among the exposed versus the unexposed mice.

The study simulated the type of nicotine exposure that occurs with smoking a hookah, which the researchers verified by measuring the levels of cotinine, the nicotine metabolite.

In May 2019, the American Heart Association published a Scientific Statement, “Water Pipe Smoking and Cardiovascular Disease Risk,” to analyse available research on the health effects.

The statement noted that tobacco smoking results in inhaling significant levels of toxic chemicals such as carbon monoxide and particulates from tobacco that can harm blood vessels, the heart and lungs, as well as creating a dependence on nicotine.

This study provides additional evidence that, contrary to popular belief, smoking hookahs adversely affects cardiovascular health.

“Water pipe smoking, which is becoming more popular in Western countries, is perceived as less harmful than cigarettes, yet hookahs carry a toxic profile that is thought to be comparable or to even exceed that of traditional cigarettes,” Khasawneh added. (IANS)
