I think the introduction of the 24hr drinking culture was a very bad idea. The idea that somehow the british people would embrace the cosmopolitan ideals of our European neighbours was rather short-sighted.
The attitudes towards alcohol of a good portion of the British society has been well documented in recent years. Everything from the 'Club Reps in Ibiza' to 'Street crime UK'. Most of the programs center on the ability of British people to get absolutely trolleyed 7 days a week.
Throughtout History we have gone OTT on alcohol. Drinking sensibly is a phrase which isn't in most people's vocabulary.
So the introduction of 24hr drinking had exactly the opposite effect of what was intended. People saw the introduction of 24hr drinking to be an excuse to drink more.
There are however, mitigating circumstances to the drinking culture. As you well know, the cost of housing in the UK has gotten to astonomical proportions. There are lots of young people who are earning a decent wage but have nothng to channel this money into since they can't afford housing. More and more live at their parents, but still have a large pay packet so they tend to just piss it up the wall.
It's also to an extent, part of social inclusion. I have first hand experience of this since not going out on the piss for nearly a year now. The number of people that i see now has significantly reduced. People who i regarded as friends, were in reality, more drinking buddies. so id say that people don't wanna feel left out so they just join the drinking club.
As for the smoking ban:
Being a smoker myself, i have noticed the difference. I somehow feel like some sort of irresponsible social lepher who is left on the fringe of society by my choosing to smoke. Im not against the smoking ban, and i think that banning smoking in city centre pubs and restaurants is a good thing. However it is in the working mens clubs mosly centered around the industrial heart land of the North East where the biggest impact has been felt.
Most of these clubs are attended by the industrial working classes and while its true that not all of these people smoke, it is in most cases that the non smokers are in the minority. In my local working mens club the number of members attending since the introduction of the smoking ban has significantly reduced, to the point where the management are considering the economic viability of the club.
I see the intorduction of the smoking ban as the death knell to social clubs.
Hope my comments have aided you in your work.
