A teaching assistant caught driving under the influence of cannabis was fined £120 after claiming she used the drug as a medicine for 'pain management'.
Mother of one Megan Washington, 26, was stopped by police in her Vauxhall Insignia with a youngster in the passenger seat after a tip-off she might have been smoking the drug before getting behind the wheel.
Tests showed Washington was slightly over the limit for THC, the principal active ingredient of cannabis, and also BZE, the breakdown product of cocaine.
When quizzed, Washington - who is understood to work at a secondary school - said she been using cannabis for pain management, but was seeking professional help to wean herself off it.
She claimed she had not realised that the drugs were still in her system and would not have driven if she had known.
