Researchers criticise study claiming e-cigarettes may lower chances of successfully quitting

January 18 2016

A new US study claims that smokers who don’t use e-cigarettes are more likely to quit smoking than those who use them.
But experts have been quick to point out the numerous limitations of the study, with the conclusions being at best preliminary or at worst “grossly misleading” according to Professor Peter Hajek, Director of the Tobacco Dependence Research Unit, Queen Mary University of London.

Researchers from the University of California, San Francisco, reviewed the findings of 38 e-cigarette use studies from around the world and concluded that smokers who use the “vaping” devices were 28 per cent less likely to successfully give up smoking tobacco compared to those not using e-cigarettes.

claiming e-cigarettes may lower

The contested results are in direct conflict with many of the claims made by tobacco-control scientists and advocates, as well as previous reviews that suggest e-cigarettes are safer than conventional tobacco cigarettes and may lead to cessation.

“The irony is that quitting smoking is one of the main reasons both adults and kids use e-cigarettes, but the overall effect is less, not more, quitting,” co-author Stanton Glantz said in a statement issued by the university.

“While there is no question that a puff on an e-cigarette is less dangerous than a puff on a conventional cigarette, the most dangerous thing about e-cigarettes is that they keep people smoking conventional cigarettes.”

However, Professor Linda Bauld, Cancer Research UK’s prevention champion, said: “Despite being wide-ranging the paper’s conclusions are tentative and sometimes incorrect.”

She went on to explain that the studies included in the review were too different in design to directly compare and many don’t include adequate measures of use or cessation.

Further, some of the devices they included are no longer available on the market, some relevant literature is excluded and the way some of the studies are set up means they miss the people who have succeeded in quitting using e-cigarettes.

“We should be very cautious about assuming that this review tells us that e-cigarettes don’t help smokers quit. Other evidence suggests they do – and this is particularly relevant for the UK where smoking rates have continued to decrease as e-cigarette use has increased,” she concluded.

Hello all. Smoked since I was 11. Alot of years! Smoked roll ups all my life. Part of the habit was the enjoyment of making them. Those who don’t smoke do not seem to understand or believe that many smokers really want to stop. I had tried a very basic e-cigarette. OK but no stopping smoking. 18 months ago I ran out of tobacco completely. Thought I had emergency stash in the car but no. No chance of buying tobacco for at least 3 days! Dug out the e-cigs and to my surprise got by no probs. Decided to stick with the e-cigs until I ordered a ‘proper’ vaporiser. I have not smoked since. Here’s the very big surprise for me though. I have not even thought of smoking tobacco at all. Not once! Everyone is different of course. But for me, the trick it seemed, was to have absolutely no access to tobacco at all for just 3 days whilst starting off with e-cigarettes. Anyhow, apologies for the long post. I am a quitter – no doubt!

I tried everything to quit smoking & vaping is the only thing that let me quit for good. Almost 3 years smoke-free now, & never have had the slightest urge to pick up a cigarette, thanks to vaping. I can’t recommend vaping enough, especially to those that have tried all the other methods out there! Good luck to all those still fighting to kick the habit!

I started smoking when I was 15, I tried to quit smoking using the patch and gum, by cutting down to none, etc… each time I may I quit but only for a week or so. The longest I ever quit was when I was pregnant and nursing, as soon as I stopped nursing, I went right back outside and started smoking again… In 2012 a friend introduced me to an e-cig, that night I ordered my first e-cig within a week I started vaping. Initally I vaped 12mg nicotine flavor mixed with tobacco for 2 weeks, then 6mg just flavored e-juice. After 2 weeks I was completely cigarette free, nicotine free after 6 weeks. I still vape because I love the flavors. I can leave my house and forget my vaporizer and not think twice about it. When I smoked, if I didn’t go back home to get my cigarettes, I would stop at a store… My family who either smoked or dipped now vape and my close friends now vape.
With all that said…I would like for the people who performed the study to please explain my family, my friends and myself

I smoked cigarettes 34yrs. E-cigarettes help me quite over 3yrs ago. Yes, I still vape but lost the chronic burnt throat, cough and stench of the government’s allowed cigarettes, with the 4000 chemicals…vs e-liquids half dozen. Political rhetoric.

Well here goes: I’ve just bought an Innokin Endura T22 complete vaping system, after giving it a lot of thought & I am about to start using it.
i started smoking at about 8 years old, in the early 1950s, being born into in a family of seasoned smokers & I rapidly became addicted like everyone else around me.
I continued smoking for the next, nearly, 50 years.without any apparent problems when, about 10 years ago, i became involved with a family member’s attempt to stop using heroin & i decided to try to coincidentally, deal with my own lifelong addiction. to tobacco, in order get a better understanding of her difficulties with heroin addiction.

Soon after deciding to do this, I was lucky enough to to find an ad in an evening paper requesting smokers, wishing to quit, to sign up for a trial into a new drug Varenicline , which was thought to enable smokers to reduce their craving for nicotine. The trial was successful & it is now marketed as Champix,& available through your family doctor in UK. this drug has enabled me to drastically reduce my tobacco intake & I often go for months without smoking.

In my case however, I also, enjoy the occasional spliff, but whenever i indulge in this harmless social pastime I rapidly become addicted to tobacco again & have to start the same process again.
i hope that vaping will show me a way out of this impasse. i realise a small pipe might be another solution i might try but have chosen vaping. will keep you appraised of progress ..

13 years of smoking and one month free of cigarettes until now thanks to vaping without it was impossible for me to quit smoking more than 2 days even using patches and gum which lead to double the amount of cigarettes smoked and now miracle happen I even don’t want to think about cigarettes thanks to vaping 🙂

It’s hard to stop smoking and only person which is addicted understand it I even saw how my father died from lung cancer and I still was too weak to quit smoking until this time – vaping is a gift of 21 century.

I to have tried everything. I started when i was nine thanks to my older sisters friends. Establishments that had machines and the local 7 Elevens we had back then in MN that sold to minors. Quitting was the hardest thing i have ever had to do in my life. After years of failure and anxiety daily because it had such a hold on me, my life,my clothes and car stunk, i carried my children while smoking, i spent all my money on them. I FINALLY have been smoke free for over a year. I can go all day without my ecig if i am busy, i just dont think about it. I wash my clothes in downey and i smell good. I hate the smell of smoke now. If i wanted to quit i know i could. I can walk up six flights of stairs without gasping for air now. I can jog and get a cardio workout without feeling im gonna die. Am saving so much money. I used both ecig and cigarettes first week dwindling down on actual cigarette. by end of week i enjoyed the flavor of e juice more and quit buying cigs. I’ve gone from 21mg of nicotine to 12mg and am almost there. 41 now started when i was 9. That’s alot of years the tobacco company had a hold of me.

I had smoked since I was 11 yrs old. In 2009, at 44, I was diagnosed with Adult respiratory distress syndrome (my lungs quit working and I had to be put on a respirator). Unfortunately my doctor told my husband that only 20% that get ARDS live and that I would die the respirator(which husband already knew since his father had passed away from it 10yrs before-he had never smoked day). I fought like hell to live but the first thing I did was light up. Shortly afterwards my husband bright home first vape pen and refused to allow me cigarettes! I’ve been smoke free since! According to doctors, my lungs look like I quit smoking over 15 yrs ago! It had quite literally saved life
