Lot of assumptions in that bud. Legislation is not a panacea by any means and theres no doubt that there will continue to be users but there's been no evidence of any increases in countries that have undertaken this path already.
There's been tons of positives coming out of these areas in regards to the huge reduction in deaths, lower crime, lower HIV rates, better health and lower incarceration rates. Its almost certainly cheaper too so you get all of those benefits for a lower or equal cost.
Thing is that we need to have the conversation as a country rather than just stick with a plan that we know 100% doesn't work.
I don't think we're that capable of having that in this country though. Certainly not in this generation but perhaps in my kids time, we'll be ready.
There's no doubting that drugs have a huge impact on society, especially in a place like boro which is so badly affected.
