The hubble-bubble bars are something that have attracted the attention of health chiefs as there was a triple rise in these bars in high street premises offering shisha, Middle Eastern tobacco pipes, which are a fast-growing trend with young people.
There has been a rise in these bars after a ban on smoking indoors was put in 2007 and this followed an increase in shisha bars. In these bars flavoured tobacco is burnt on coals and sucked through an ornate water vessel before being inhaled, according to the British Heart Foundation.
BHF said, "We're trying to raise awareness that the smoke inhaled in an average shisha session of about one hour is equivalent to 100 cigarettes. Shisha is on an upward trend particularly among 18- to 24-year-olds for whom it constitutes a social pastime in a way that smoking cigarettes doesn't anymore."
When smoking was banned there were about 179 such bars but since then there has been a rise and these bars are now 556 in number, according to 133 local authorities in the UK.
Cities like Manchester, Leicester and Newcastle where there is much student population and this only accounts for much of the growth.
