Juul has launched a bluetooth-connected e-cigarette on the UK market that can monitor users’ vaping and track their devices, BBC reported.

The Juul C1 e-cigarette pairs with an Android smartphone to limit who can use it and to monitor how often the user vapes. According to the BBC, Juul said the C1 “could only be used if people got through age-verification and face-recognition checks”. Juul had previously been criticised for its products being widely used by teenagers.
Juul UK boss Dan Thomson told the Financial Times that the C1 “could only be bought and used after customers went through ‘stringent checks’ to verify their age and identity”.
Via the app, owners will be able to monitor how often they vape, how many puffs they take and locate their device if it is lost, BBC reported. Juul confirmed that it collects the data itself, but said it was only to help manage customers' use of the products. It said it would not sell or share the information without the users' explicit permission.
A similar app-controlled e-cigarette, the Vype iSwitch by BAT, went on sale in the UK in December 2018.
