Footage from a vape factory in Shenzhen has drawn attention to the gruelling work involved in quality testing disposable e-cigarettes, as health experts warn of rising dangers associated with vaping.
The clip shows workers inhaling from multiple devices in quick succession to verify they function correctly and deliver consistent flavour. Such practices have become standard in the region's manufacturing hubs. Workers claim that they test 8,000 to 10,000 units per day.
