Cannabis farm

The New York-based Applied DNA Sciences wants to differentiate between state-compliant and illicit market cannabis by spraying DNA tracking tags on the plants, but some advocates are concerned about regulatory overreach and safety.

Despite some marijuana being “legal” for medical and adult use in many parts of the United States, the vast majority of the cannabis still being produced and consumed is “illegal.” One company, Applied DNA Sciences, is now seeking to stake a claim in the cannabis industry by providing supply chain tracking through spraying a molecular DNA tag onto the buds themselves.

Applied DNA Sciences says that they’re seeking to provide law enforcement and regulators with a way of determining exactly which buds were grown legally and which weren’t — and they are already working with state governments to require the use of their tracking system.
