A array of sweet smells are being offered to pubs in England to help them hide unpleasant odours that may become apparent once the smoking ban comes into force on Sunday.
Stale beer, old buildings and the odd whiff from hygienically challenged drinkers could pose a problem once the scent of tobacco has lifted for good.
Now the firm Ambius is offering pubs devices which will leave them smelling of crisp cotton, apples or roses.
Jeff Mariola, managing director of Ambius, told Reuters: "Most people think with all this smoke going away everything is going to be fine and dandy.
"The reality is, when you remove the odour, you are left with what you couldn't smell ... it's going to hit everyone right in the face."
Ambius is a unit of services group Rentokil.
A number of provinces in Canada and states in the US, including New York and California, have had strict anti-smoking laws in pubs and bars for years.
The ban came into effect in Scotland and Wales earlier in the spring.
