I dont deny that there are a lot of people no doubt coming to you with alcohol related illnesses. Are they all young'uns though? Or are a lot of them fat, sweaty alcoholics who actually dont bother anyone else except for themselves? I suspect an equal measure, but I mainly suspect that its the young'uns who arent ill, but actually end up in A&E...
And as for louts, well, they often say drink brings out the true person inside... so if they are louts when drunk, then they would likely be louts if they had no access to, or be able to afford, drink. Maybe they'd go and mug an old granny for a £7 pint of beer...
