Britain’s Deadliest Addictions follows three people addicted to different substances – alcohol, class A and prescription drugs – as they attempt to kick their habits under the supervision of experts at a leading detox clinic.

Presented by Krishnan Guru-Murthy and addiction psychologist Dr John Marsden, the series looks at the terrible effects of Britain’s growing addiction epidemic and what addicts can do to break the cycle.

The series highlights the harsh realities of the different addictions and hears about the effects from families and friends, while the experts explain how people become addicted, how substances act on the body and mind, and what can be done to help. After two days of treatment the patients will be dealing with the full effects of withdrawal and discovering the damage they’ve done to their bodies and minds.
