A woman has shared her warning after being left unable to use her legs from a "laughing gas" addiction that saw her use 600 canisters a week.
Kerry-Anne Donaldson, 26, relies on a wheelchair after "abusing" nitrous oxide (NOS), also known as "laughing gas", for years.
The former receptionist, from Newham, East London, says she first started using NOS at parties when she was 18, and gradually increased her usage.
