Braintree's first vape shop is celebrating three years on the high street.
Charlie Charalambous opened Vapours in 2015 after using electronic cigarettes to quit smoking himself.
Since then, he believes he has helped hundreds of smokers kick the habit.
In conjunction with healthcare company Provide the store now offers the carbon monoxide 28 day challenge.
This is where people wanting to quit smoking take a CO tests on day one of stopping and then again on day 28 to see how much it has dropped.
Mr Charalambous said: "This is a great incentive to push people into quitting.
"Sometimes people need a mental goal to follow, giving that little bit of extra will power.
"It is also nice for myself when I see people succeed and the look on their faces when they realise their sense of accomplishment."
Mr Charalambous said he was grateful to all his customers over the past three years and is looking helping more people quit in the future.
