Not saying there still isn't a massive opioid problem in Manch Vegas, but the BBC mini-doc was published, I believe, in 2015. Manchester is, from an outsiders perspective, getting better (i.e. more private investment in housing and technology). It seems to me to be a smaller version of Dover from about 10 years ago. Dover definitely isn't Shangri La (sp?) but it's vastly improved owing to developers' investment. Some of these same developers are now eyeing Manchester as are others. I expect it to be much better in less than a decade. JMO.
