Dr Gillian Tully says police forces are rationing toxicology work on suspected drug drivers
Police forces are having to ration forensic toxicology work, especially samples from suspected drug drivers, because there is not enough capacity in the system to handle the volume of work, the outgoing forensic science regulator has said.
Dr Gillian Tully, who steps down from her post after six years on Tuesday, said the service needs to be treated as critical national infrastructure and given the funding and regulatory powers necessary to maintain the integrity of the criminal justice system.
