Alcohol apparently has tightened its grip on Australians and condition is getting worse as the day passes by, experts claim.

The warning seems to have increased the number of alcoholic’s admissions to one of Sydney's leading drug rehabilitation centres. Alcohol was vital drug for concern for about 40 per cent of people getting entry into Odyssey House in the past financial year, as evaluated about the fact that a quarter of admissions the year before.

Odyssey House chief executive James Pitts has worked close with alcohol and drugs in the recent past and been the same for 30 years, but claims that the stats the rehabilitation service's annual report will come as a surprise.

"We've seen this trend over the past three years prior to this year where the people who are actually reporting into our residential program increasingly have reported alcohol as their primary drug of choice," he added.

Mr Pitts claims that alcohol-related admissions at Odyssey House were at the increased level in 33 years, but at the same time have major roles at the play.

He further added:"It usually is probably a year or two-year lag time before the people who it affects most adversely - in other words, the people who had the problems - actually report for some type of health at a treatment centre.”

The director of the National Drug Research Institute at Perth's Curtin University, Professor Steve Allsop, claimed that Odyssey House is not the one experiencing a surge in alcohol-related conditions.
