Harvest boon: A new Applied DNA tracking system designed to secure legal-marijuana supply chains comes just as the international cannabis market is booming.

Just six months after announcing a partnership to develop a new molecular-tracking system, a Long Island biotech and a Canadian medical-marijuana supplier are launching the world’s first cannabis tagging system.

Stony Brook-based supply-chain, anti-counterfeiting, anti-theft and product-authentication specialist Applied DNA Sciences and Calgary-based pharmaceutical-solutions provider TheraCann International Benchmark Corp. on Tuesday announced the launch of ETCH Biotrace, which leverages Applied DNA’s CertainT platform to tag, test and track cannabis plants “in commercial harvests of any scale,” according to the Stony Brook biotech.
