Police say they are particularly concerned about a seizure of dangerous drugs being disguised as children's Lego bricks on the streets of Totnes.
A woman was stopped and searched with the bags of colourful drugs in the town centre. Police say the ketamine was worth about £1,000 and she was also in possession of 75 MDMA tablets.
Police are warning that they are particularly concerned about dealers targeting young adults and teenagers.
The woman's house was later searched and an investigation is ongoing.
