I think it's difficult to just attribute most of it to what happened 30 years ago. Given the increases in the last 5 years and the outlier numbers against the rest of the UK and Europe, there has to be some question of the Scottish govts actions. I know that some efforts in terms of drugs safe rooms have been blocked by WM, but that's not putting Scotland out of line.
I'd contest that.
We noticed the first spike of heroin injectors around 1992, NS.
A feww of them overdosed in the intervening years, bnut now, many in their mid fifties are experiencing health issues directly related to the addiction.
Worse than that, they have passed on that addiction to the next generation - not through genetics, but emulation.
Combine that with endemic poverty, underachieving, and you have the perfect conditions for the addiction to spread.
Add the fact that the original aim of the methadone programme was to first wean them off heroin, then, by gradually decreasing the dosage, methadone.
Trouble is, the methadone dosage remained the same, and addicts, whilst taking the drug, sought their highs elsewhere, gaining further addictions as a consequence.
