vicious cycle of social exclusion and drugs problems and fractured communities" in cities such
as Birmingham, Liverpool and Manchester.
Professor Hamid Ghodse claims parts of the cities are becoming no-go areas where drugs
gangs are effectively in control.

celebrities normalising drug abuse.
"Drug traffickers, organised crime, drug users, they take over. They will get the sort of
governance of those areas.
