Pupils from Marine Primary School in Ocean View graduated after taking part in a 16-week drug counselling and awareness campaign presented by Hope House Counselling centre in Bergvliet.
The pupils were made aware of the negative effects of drugs and how drug abuse can destroy a family.
Each pupil was presented with a certificate at the graduation on Monday November 6.
Marine Primary School principal Wayne Lawrence said he was delighted to have had Hope House at the school.
Mr Lawrence had contacted Hope House earlier this year after it emerged that some of the pupils might be using drugs. All the pupils involved in the programme were tested for drugs and their results came back negative.
Ocean View police spokesman, Sergeant Leon Fortuin, said Hope House had partnered with the SAPS for various projects for a few years now and the work they are doing is remarkable.
“The amount of success which Hope House has achieved in the Ocean View area is quite extraordinary.
“Hope House will again identify a school in the new year where the same programme will be run,” he said.
