Five young people are facing drug charges after an undercover OPP investigation.
Collingwood and the Blue Mountains OPP assigned undercover officers to patrol the area, after concerns about drug activity by youths around high schools.
After a lengthy investigation, five youths were charged during separate incidents, and marijuana and drug paraphernalia were seized.
The five can't be identified under the youth criminal justice act.
Police aren't saying which high schools were affected or what charges have been laid.
