I agree that booze is a big problem here but I don't hear of many crimes related to getting money to buy it whereas with drugs you do.

Earlier this year I was on a cruise that terminated in Santiago,Chile and when we disembarked every single person had to stand in a line in the reception area with their baggage in front of them while a team of sniffer dogs and police with guns went up and down the lines,the whole process for over 2.000 people took less than 40 mins.

So if the IOM is really keen to stamp out drugs it can.....if really has the heart to.
