The State Government and WA Police will target the supply of methamphetamine in Western Australia, unveiling its new meth enforcement action plan.

Police Minister Liza Harvey said under the plan, WA Police would establish Meth Transport Teams to target supply routes into the State.

And about 1.8 million West Australians will be subjected to a giant, anonymous drug test as the Government analyses wastewater for methamphetamine to try to shock users off the drug.

On 6PR Mornings, Gary Adshead spoke to the Police Minister, as well as Palmerston chief executive officer Sheila McHale and 6PR listener Phil, who described how the drug has affected his family.
