Kim Ledger is taking that opportunity, just as he believes his son would have done had the roles been reversed.
Mr Ledger has become the patron of ScriptWise in the Ledgers' home country of Australia, a not-for-profit organisation that aims to prevent prescription medication misuse and overdose fatalities.
He will today address delegates of the Cutting Edge Addiction Conference in Rotorua, sharing the benefits not only of his personal experience of losing a child to an accidental prescription drug overdose but the research he has since carried out.
He says addiction to prescription drugs and the accidental mixing of those drugs, as happened with his son, are massive issues that need to be talked about. He wants to help raise awareness, to stop other families going through the pain his has.
There can be a casual attitude around prescription drugs - if they are legal and prescribed by a doctor then surely they can't be too harmful, right?
Wrong. And Mr Ledger and the other experts at this week's conference are to be commended for their efforts to put that myth to rest.
