This is a problem that simply can't be ignored any longer and it if it is, could end up with terrifying and awful consequences.
Schools might think that by being adamant they have no problems, that they are telling their constituent parents what they want to hear. Deny it all and parents can be reassured that drug testing First XV kids is yet more bureaucratic madness: that a box ticker in some unnamed OSH department has enjoyed a major victory.
Drug Free Sport New Zealand is in danger of being seen as the public face of this madness and portrayed as the big, bad wolf having made the decision to institute random drug testing at next month's national Top Four Championship.
Concerns have already been raised about privacy issues, about the ethics of testing what are, in some cases, children rather than young adults.
But DFSNZ is most definitely not the bad guy. It is definitely not over reacting and if it is playing any role in what will inevitably be branded a war on illicit substance taking in New Zealand schools, it is that of saving schools from themselves.
DFSNZ has its suspicions that supplement taking is extensive within this age group. What it needs now is some kind of hard evidence to confirm they are right.
If there are positive tests, schools will be compelled to take the issue more seriously than they currently do. They will be under pressure to monitor their players better and provide deeper, more extensive education about the dangers of taking supplements and other substances.
It is too late to imagine the horse can be put back in the stable in regard to reducing the perceived importance of rugby within the culture of all boys' schools.
It's too late to believe that First XV players across New Zealand can be reprogrammed to accept that only a tiny number of them are actually good enough or well enough equipped to make the professional ranks and that they should just enjoy the experience for what it is rather than view it as a pathway to a well-paid career.
The wider situation can't be changed but it can be better managed and it will begin with the major rugby schools accepting that not only is there a major problem with supplement use, but that they are duty-bound to do what they can to help eradicate it.
