More than 200 tablets were left dumped on an Arbroath street just across from a school.
The tablets were lying on the road in the town’s Newton Crescent where residents have previously found drugs paraphernalia.
One resident said it was “totally unacceptable.”
“A child could have picked the pills up,” he said. “We are determined to clean up this area.
“There are good people living here and there’s no way we are going to let others give us a bad name.”
The medical waste was reported to Angus Council, who attended to uplift the items as a matter of urgency.
Bags of dumped rubbish were also left in a field at St Vigeans which were removed by the council.
A council spokesman said: “The medical waste was reported to us and we attended to uplift the items as a matter of urgency.
“The flytipping at St Vigean’s was also reported to us and removed from the area.
“Enquiries have also been undertaken in an effort to trace who was responsible.
“We would appeal to anyone who could assist in this regard to contact us on 03452 777 778.
“Angus does not suffer the same levels of fly-tipping that other parts of the country experience, however, we are not immune to such behaviour.
“Fly-tipping can be dangerous, harm the environment and can prove costly to clear.”
