Mr. Padraig Cribben:

There is no average, which is the problem. As Mr. O'Keeffe stated earlier, it depends on each individual. Members spoke earlier about accepting international science. The accepted international science is it takes an hour for a unit of alcohol to go through the system. That time could actually be 45 minutes for me and an hour and a quarter for the Chairman, depending on individual circumstances. Where an action is wholly unintentional and people are trying to comply with the law, people may sometimes be caught out in a marginal fashion.
