As intensive methamphetamine use has increased in both Australia and New Zealand, associated health harms have also increased.

• In Australia, hospitalizations and the number of people in drug-related treatment related to methamphetamine use have increased over the long-term, although recent data suggest these trends may be stabilizing.
• In New Zealand, screening instruments used in large population surveys indicate an increase in amphetamine use disorders between 2016 and 2023.
