Is Australia’s nicotine habit evolving right under our noses?

Recent data from our nation’s wastewater treatment plants has revealed a surprising trend: despite long-standing efforts to curb smoking, total nicotine levels are not falling—and in some areas, they’re on the rise. But is this a resurgence in traditional smoking, or are we witnessing a massive, hidden "vaping boom"?

We’re joined by Distinguished Professor Brian Oliver, a leading respiratory expert from the Woolcock Institute of Medical Research. We’re diving deep into the science of wastewater surveillance to understand why it’s so difficult to pinpoint where that nicotine is coming from.

From the rise of synthetic nicotine and illicit imports to the "Wild West" of the unregulated vaping market.

Whether you're curious about the science or concerned about the public health implications, this is the clear-eyed look at the "vaping mystery" you’ve been waiting for.
