Uruguay to track legal pot from seeds through genetics and radio frequency tags

Uruguay's drug czar says every legal marijuana plant in the country will be registered and tracked using radio frequency tags and genetic markers to make sure what's grown there stays there.

Julio Calzada has described the plans for Uruguay's government-run marijuana market in an interview with The Associated Press. He says the rules will be published next month and the first government-grown plants won't be ready until the end of the year. He says it will take that long to harvest genetically identical pot from cloned plants whose product can be identified as legal by the authorities.

Uruguay also will use radio-frequency tags to track plants and products. Calzada says the government already uses the same technology in the beef industry.
