A “quite frightening” number of children as young as seven are being used as drug mules in County Louth, a local TD has warned. Fine Gael’s Paula Butterly said she visited three schools in her constituency before Christmas and was shocked by what she learnt from local teachers. “Some of their children, right down to the age of seven, are coming into the classrooms high,” she told The Pat Kenny Show. “In a lot of cases, the mothers in particular because perhaps the fathers aren't present, they are afflicted by addiction themselves,” she explained. “We have a project there called the Green Town project, which is in Limerick, and I brought that to Minister O'Callaghan before Christmas,” she said.
