Concurrently, bimonthly wastewater samples from metropolitan sites were analysed for amphetamine and methamphetamine concentrations, with methamphetamine serving as a control as its use was unlikely to be affected by the shortage. Data were compared from February 2022 to December 2024.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In WA, lisdexamfetamine DDDs increased from 5.59 to 13.02 and dexamfetamine from 2.55 to 6.03 per 1000 population per day, doubling combined stimulant DDDs from 8.14 to 19.05. In SA, lisdexamfetamine DDDs rose from 1.05 to 5.00. Wastewater amphetamine levels fluctuated (WA: 5.07\u201317.10; SA: 0.79\u20133.46 doses\/day\/1000 people) but declined sharply during shortages, while methamphetamine levels remained high (peaking at 62.65 in WA and 66.22 in SA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Triangulation revealed variations in lisdexamfetamine use during shortages and highlighted potential behavioural responses.
