People are being urged to drink responsibly after a new study found 10% planned to consume more than 40 units of alcohol on a night out.
According to researchers, this would see women exceed their weekly alcohol limit by nearly three times the recommended amount, while men would consume double.
Drinkers in Liverpool, Manchester and Chester were involved in the study. When interviewed, half said they were drunk at the time.
Of the 214 who took part, 51% said they intended to carry on drinking. They were required to complete a series of interviews, breath tests and assessments of their levels of drunkenness, such as slurred speech and ability to walk.
From the overall sample, 80% said they intended to drink more before returning home, with one in 10 (15% of men and 4% of women) believing their total alcohol intake would be more than 40 units before bedtime.
At the time of the interview, one in five men (20%) and 21% of women had already drunk more than their weekly recommended alcohol intake (21 units for men and 14 for women).
By home time, this was expected to rise to 61% of men and 45% of women.
More than one in five men (21%) were expecting to have been drinking for more than 12 hours by the time they returned home.
Mark Bellis, from Liverpool John Moores University, led the research, published in the journal Substance Abuse Treatment, Prevention and Policy.
He said: "Implementing safety measures in nightlife environments is crucial to protecting public health, yet without reasonable efforts to reduce nightlife alcohol consumption, such measures may simply result in safer environments for drunks."
