SPOKANE, Wash. -

Before legal marijuana hits the streets the state is requiring a strict documentation of each plants movements as regulators want to know every step in the pot-growing process down to every leaf.

The system that will be used to regulate the state's new marijuana industry can monitor the growth of marijuana at every grower's site and see if someone is illegally using it for themselves.

The system the state will use is called Biotrack THC, a Florida-based company that's developed software and marijuana tracking systems.

"You'll always know which plants came from which batch," Biotrack THC director of marketing and sales Anthony Stevens said.

The company said it can track marijuana from seed to sale with their software using barcodes. Each plant has an icon and once input into the system it can be viewed by the grower and the state.

It's similar to how stores track product. A barcode can be scanned at each place it arrives and when it's sold. The big question for Biotrack THC is what prevents growers from tearing off the barcode and keeping the pot for themselves.

"This program will definitely, definitely help out with streamlining where that went to," Stevens said.

The grower can also keep track of every employee's movements through detailed data entry and find out who's been taking the pot. If it’s the grower stealing from their own crop the state would have to detect it and enforce it.

"This software can do quite a bit, and notate quite a bit, but us as humans there are ways around it," Stevens said.

A traceability system is required for everyone in the industry and there are others out there. The Biotrack THC software will cost growers between $250 and $400 a month.
