As Isis (Islamic State) is driven out of Iraq and Syria, militants in the last throes of battle are turning to P in desperation.
Isis's self-proclaimed "caliphate" effectively collapsed in July when Iraqi security forces reclaimed its previous stronghold Mosul.
US Army Colonel Ryan Dillon says there is increasing evidence
of Isis fighters using methamphetamine to help them stay alert during fighting.
"There were several Isis fighters that had track marks on them from taking something intravenously and that was assessed to be methamphetamine," the Combined Joint Task Force-Operation Inherent Resolve spokesman told AAP from the Middle East.
Among the short-term effects of methamphetamine are increased confidence, alertness and energy.
