Has it dropped significantly? Perhaps the figures are affected by young Irish and non-Irish nationals leaving.Consumption of Alchol in Ireland has dropped for the last four years, even as prices have dropped and availability is better.
For sure it's not a cost or availability issue, it's simply a matter of attitude. The State should manage the expectations of Pubs & Off Licences, that if they serve drunken or under age people they will be closed for a period (and if they repeatedly do so the closure periods should lengthen). Also manage the expectation of drinkers that if they are falling about in public, a danger to themselves or others, they'll spend a night in a Drunk Tank and pay a premium for the pleasure. Courts should not view the excuse of drunkenness as a mitigating factor but rather it should militate against lenient sentences.
