Juul Labs is today launching a pilot for its new Track & Trace program, which is meant to use data to identify exactly how Juul devices wind up in the hands of minors.

Juul vaporizers all have a serial number down at the bottom, by the Juul logo. However, it wasn’t until recently that Juul had the capability to track those serial numbers through every step of the process, from manufacture to distribution to retail to sale.

With Track & Trace, Juul is calling upon parents, teachers and law enforcement officials to come to the Juul Report web portal when they confiscate a device from a minor and input the serial number. Each time a device is input in the Track & Trace system, Juul will open an investigation to understand how that minor wound up with that device.

In some cases, it may be an issue with a certain retail store knowingly selling to minors. In others, it may be a case of social sourcing, where someone over 21 years of age buys several devices and pods to then sell to minors.

Juul will then take next steps in investigating, such as talking to a store manager about the issue. It may also enhance its secret shopper program around a certain store or distributor where it sees there may be a spike in sale/distribution, to youth to identify the source of the problem. To be clear, Track & Trace only tracks and traces the devices themselves, and does not use personal data about customers.

Juul isn’t yet widely publicizing Track & Trace (thus, the “Pilot” status), but it is focusing on Houston as a testing ground with banner ads targeted at older individuals (parents, teachers, etc.) pointing them to the portal. Of note: The ad campaign is geofenced to never be shown in or around a school, hopefully keeping the program a secret from young people illegally using Juul.

The company wants to learn more about how people use the portal and test the program in action before widening the campaign around Track & Trace. That said, the Report portal is not limited to Houston residents — anyone who confiscates a Juul can report it through the portal and trigger an investigation.

“It’s important to note that the pilot is an opportunity for us to learn how the technology is working and optimize the technology,” said Chief Administrative Officer Ashley Gould. “It’s not just at the retailer level. It’s a whole process through the supply chain to track that device and find out if everyone who is supposed to be scanning it is scanning it, and the software that we’ve created to track that serial number through the supply chain to the retail store is working. The only way we’re going to know that is when someone puts in the serial number and we see if we have all the data we need to track it.”

According to Juul, every device in production will be trackable in the next few weeks. In other words, Juul vapes that are years old are likely not fully traceable in the program, but those purchased more recently should work with the system.

Juul has been under scrutiny from the FDA and a collection of Democratic Senators due to the device’s rise in popularity among young people. Outgoing FDA Commissioner Scott Gottlieb has called it “an epidemic” and enforced further restrictions on sales of e-cig products.

Juul has also made its own effort, removing non-tobacco and non-menthol flavored pods from all physical retail stores, enhancing their own purchasing system online to ensure online buyers are 21+ and not buying in bulk, going after counterfeits and copycats posing as Juul products and exiting its Facebook and Instagram accounts.

But Juul Labs also committed to build technology-based solutions to prevent youth use of the product. Co-founder and CPO James Monsees told TechCrunch at Disrupt SF that the company is working on Bluetooth products that would essentially make the Juul device as smart as an iPhone or Android device, which could certainly help lock out folks under 21.

However, the Track & Trace program is the first real technological step taken by the e-cig company. And it has been an expensive one. The company has spent more than $30 million to update its packaging, adjust printing standards, change manufacturing equipment and integrate the data and logistics software systems.

For now, Track & Trace is only applicable to Juul vaporizers, but it wouldn’t be shocking to learn that the company was working on a similar program for its Juul Pods.
