Researchers have based their findings on a survey that examined the lifestyles of 3,000 people in Britain, aged less than 30 years.

In the poll, the respondents were asked on substances and habits which they spent the most money on, those they had previously attempted to cut down on or give up and the modern impulses ruling lives in 2009.

Coffee topped the list of the ten most common modern addictions, followed by chocolate consumption with Facebook in third place. What's surprising is that the much railed against vices of alcohol and drugs didn't figure in the top ten.

Vanity came in the fourth place as a more traditional popular vice with beauty products while the practice of often checking bank accounts came fifth, thanks to the global credit crunch, 'The Daily Telegraph' reported.

Men and women showed differing rates of addiction with 17 per cent of males not being able to go a full day without sex, compared to a figure of just eight per cent for females.

The latest study coincides with the launch of Rehab, a programme examining rehabilitation and addiction on the Living channel.

Some 86 per cent of those asked said they would never check themselves into rehab, with 46 per cent polled admitting they had little understanding of what actually went on in many rehabilitation centres.
