If you're looking for a more convenient hookup, you might just be in luck.

A new line of super high-tech green vending machines debuted at the NAMAOneShow this week — and by "high" and "green," we're not talking about energy efficiency. The smart vending system, which has advanced features like biometric security capabilities, is built to sell weed.

American Green, the company behind the tech, has been making smart vending systems for weed since 2009 and claims to be one of the largest cannabis-related public companies in the United States. They're calling the new machines the world’s most sophisticated vending system, which is a bold claim — but if it works as advertised, it could be the key to making controlled substances more convenient to sell.

Customers looking for a fix will need a smartphone to use the machines — they can only be accessed through a linked app, which is available for both Android and iOS. The user logs into their profile and verifies their identity through their phone's biometric scanner. Then they scan a QR code that pops up on their phone screen to confirm their purchase on the machine.

It's unclear exactly how rigorous the application process for the system will be, or the types of places these machines will aim to serve. Since regulated substances like alcohol and marijuana are the intended goods for sale, it's sure to be stricter about verifying your identity than your standard app.

But the American Green team sees potential for the 21-and-up rigs.

"A baseball fan could buy a beer at the game in New York and cannabis from a dispensary in California the next day through the same app utilizing their verified account," said the company's chairman and acting president David Gwyther in a statement. "This is a huge step forward for smart retail and the automated sale of regulated products."
