The drug P is a dangerously destructive substance that has taken hold in New Zealand. It's wrecking lives, wrecking families, fuelling crime and allowing gangs to flourish.

I'm determined to confront this scourge. That's why I recently announced the Government's action plan for tackling P.

It includes cracking down on gangs, beefing up Customs drug forces, assisting more addicts to quit and restricting the availability of pseudoephedrine (PSE), the key ingredient used to make P.

Media scrutiny of our plan has centred on this final decision. I want to lay out what it means, and why we've done it.

The reclassification of PSE as a Class B2 controlled drug means it will only be available by doctor's prescription and that more severe penalties will apply to those who have it for a non-approved purpose.

It may surprise you to learn that these days most of us who purchase products like Sudafed or Codral are not actually using PSE. In fact, up to 80 per cent of the cold and flu products Kiwis purchase are instead based on an ingredient called phenylephrine.

Phenylephrine can't be used to make P.

Pharmaceutical manufacturers have been selling these alternative products since the early 2000s and most Kiwis seem happy with them. Medical evidence backs this up, suggesting that in almost all cases patients will receive similar relief from cold and flu symptoms using a non-PSE alternative.

In fact, the Netherlands, one of the more liberal countries when it comes to drug control, has banned PSE altogether, with no obvious consequences for the health of its population.

So what's driving the Government's decision? I want to reduce the amount of P available in New Zealand, to make it harder for gangs to produce and to make it easier for police and Customs authorities to catch those who deal in it.

The advice I received from both my chief science adviser, Professor Sir Peter Gluckman, and from the Expert Advisory Committee on Drugs was that further restricting the availability of PSE would help achieve those things.

Police report that up to a third of the P labs they bust in New Zealand are using domestically bought PSE as their base ingredient. Gangs and drug cooks are going to serious lengths to get it, using organised "pill-shopping" syndicates to buy it at community pharmacies.

We believe restricting the availability of pseudoephedrine will make it much harder for gangs and drug cooks to make P in NZ.
