Methamphetamine has been detected in the air in downtown Auckland in the first study of its kind in Australasia.
Traces of the illicit drug, as well as nicotine, caffeine and THC, were found at a pollution monitoring site on Customs Street near the bottom of Queen Street.
At the concentrations found in Auckland's air, it would take more than 8-thousand-years to actually inhale an active dose of methamphetamine, but the concentrations were higher than overseas cities such as Barcelona.
University of Auckland School of Chemical Sciences research fellow Dr Joel Rindelaub spoke to Ingrid Hipkiss.
