Marie funded her heroin habit by selling sex. Then she became pregnant and her daughter was taken away. Rhiannon Howells hears how they were reunited and their lives turned around. It's an ordinary yet wonderful story of mother-child bonding, but what happened next is neither ordinary nor wonderful. After leaving hospital, Marie and her partner Steve took baby Chloe back to their house in Bristol. But rather than sitting down to a cup of tea, the new mum had what she'd denied herself, yet craved, throughout her pregnancy – not a glass of wine or a cigarette, but a hit of heroin.
