Not being from the Medical fraternity, I cannot answer your question, but it is highly unlikely.
However, the report and its figures were based on the last few years, ie, for instance, Scotland had seen arise in Cirrosis of the liver in men by 10% from 2004 to 2005. The amount of females with a drink problem had doubled over the same period of time.
Personally, I do not think it is the bringing in of 24 hour drinking, although this will add to the problem. Drinking heavily, or binge drinking as been around for a long time. Certainly in my home town it has risen a great deal. In Bournemouth some 76 applied for 24 hour drinking and although a high number got extra hours, only about 4 got the full licence.
I think you will find it is down to having more money, particular in the younger scenario to splash out on booze, and lots of nights out. I have been to town on a night out and it is shocking to see the amount of youngsters out on the streets, out of their minds. I have friends and relatives in the Police, and they say their whole time virtually is taken up with drink related matters, obviously moreso at the weekends.
