Winifred Robinson tracks the movement of cannabis, from the Vietnamese operators illegally growing massive quantities in Britain to the boarding schools where heads claim it is destroying young lives.
With politicians often under fire following the reclassification of cannabis, Winifred Robinson tracks the drug from the Vietnamese operators who are illegally growing massive quantities here in Britain, to the boarding schools where heads say it is destroying young lives.
The supply networks are operating across Britain - from the poorest estates to the wealthiest schools.
Anthony Seldon, the head of Wellington College, has said the drug is wrecking lives and many are worried about the problems to come.
The programmes investigate how far these outcomes were anticipated and asks, given the changing nature of the trade, whether it is time to look again at how this drug is treated and at those addicted to it.
The series features unique access to police raids and extraordinary interviews with Vietnamese operators who have moved into the UK market and now control a vast slice of it.
