"Our message has been very well received. It's all about educating about the potential dangers of supplements in particular. It's come about through the rhetoric around random testing in schools," Kaho said.
"Supplements are so easy to find in today's digital environment and kids don't even need to step inside a supplement shop. When I was at school playing sport, it was all about bigger, better, faster and the pressure to put on weight for rugby."
The trouble is, he said, was that supplement users were totally unaware of what they were actually taking.
Wanganui Rugby Union boss Bridget Belsham said there were no issues, or evidence that performance-enhancing drugs or supplement use was widespread on her patch.
"We certainly haven't heard of any cases or event concerns," Belsham said.
Same too for Whanganui athletics guru Alec McNab who also has a high profile nationally and internationally.
The Wanganui Collegiate School master said he did not know of any cases in track and field or cross country circles.
"I guess it's only natural teenagers love to experiment and it's so easy in today's digital world, but the problem is they simply don't know what they are putting inside their bodies and even whether it works or not," McNab said.
