Figures presented in Parliament show a 15% increase in the number of teenagers receiving treatment for alcohol-related illness last year.
The number of under-18s needing treatment went up from 7,591 in 2005 to 8,582 in 2006.
According to the Mail on Sunday, the figures "deliver a crushing blow" to the Licensing Act and what it calls "24-hour drinking".
However, this time the paper blames the rise in late licences awarded to "corner shops, off-licences and supermarkets", which the paper says have been granted more than half of the 3,000 late licences handed put under the new act.
Dr Christopher Record, consultant in liver disease at Newcastle NHS Trust, told the paper: "There is no doubt that increased availability has led to more young people drinking.
"If you increase availability, you increase consumption - the two go hand in hand.
"I'm sure the rise has been caused by 24-hour drinking legislation, when you go into ( a supermarket) and buy alcohol throughout the night."
