Smokers who ditch the habit and move to vaping intead stand to save an average of £346 a year - or £1.1billion collectively, figures show.
That's according to a new study into vaping - based on how much less it costs the typical smoker a year.
A OnePoll study asked 1,790 smokers how much they were spending on cigarettes before giving up, versus how much they now spend on vaping a week.
On average, smokers said they were spending £51.22 a month compared to £22.36 a month on vaping.
It found more than half switched to save money - while the biggest benefits included smelling better and no longer having smoker’s cough.
The survey findings were revealed today at the launch of VApril, a month-long education campaign, fronted by TV’s Dr Christian Jessen to encourage smokers to make the switch to vaping.
John Dunne a director of the UK Vaping Industry Association (UKVIA), which commissioned the research, said: "There are still almost 7million smokers in the UK that are yet to see the benefits of switching on to vaping.
"We’re also hoping to educate the wider public about the differences between vaping and smoking so that they can provide vapers with the support to make the switch.”
Launching the campaign, Jessen, famous for his work on Channel 4’s ‘Embarrassing bodies’, said: "There are now more than three million vapers in the UK who have made that life changing decision to switch from smoking.
"As today’s study shows, there are whole raft of benefits to making the switch, not just on smokers’ health but financial and social benefits too. But yet, according to Public Health England, an incredible 40% of smokers have never even tried vaping."
He added: "We’re in danger of missing out on the huge public health prize of a smoke-free society if the medical profession doesn’t start encouraging smokers to take up vaping.
"Vaping has so far helped 3.2m vapers either quit or reduce smoking, saving the NHS billions in treating those with smoking related health conditions.
"There is a growing bank of evidence which shows it can reduce smoking relating harm and yet despite that, more than half of hospitals across the UK ban vaping on their grounds.
"It’s time we were consistent and gave clear advice to smokers to help combat the misinformation they are all too often bombarded with about vaping."
