In the third documentary of UNILAD’s original series: ‘The Dark Side Of Britain’, we explore the growing problem of synthetic cannabis AKA Spice, which is flooding the streets of Manchester. Spice was made illegal in 2016, but two years later we take to the streets of the UK's second city to see if this latest example of the war on drugs is working. In this episode we follow current and former users of this life destroying drug and the people trying to solve this issue once and for all.
