The advent of e- cigarettes has brought a change to the many ‘traditional’ smokers’ habits and the use of them is perfectly legal in premises, as they are not tobacco based and emit no smoke, just a vapour. Yet many licenced premises prohibit their use. Indeed, all that they contain is nicotine which has about the same affect as caffeine on the user (as stated by the BMA).
I feel confident that if licencees used a little more discretion, custom would increase irrespective of the cost of an on sale alcoholic beverage.
Traditionally, people (generally) who frequent public houses on a regular basis are smokers, like it or not.
