Very true.
Drug dealers have virtually disappeared from Dublin since people have been able to buy their chosen product legally. That can only be a good thing for society as they are no longer contributing to the gangland violence and murder which was getting out of control in parts of the city.
I appreciate this does not solve the social problem of people having access to drugs it's a start.
Even if they do close they have served a good purpose as those who are now used to paying 20 euro for a gram of something are unlikely to ever go back to paying 100.
