Feds bust another illegal grow house in Maine as authorities probe foreign drug trade in other states

The high electricity consumption of a home, its cardboard-covered windows and odor of marijuana drew law enforcement's attention to an illicit grow operation off the beaten path in rural Maine.

The bust of the home with a hidden grow operation and seizure of nearly 40 pounds of processed marijuana marked the latest example of what authorities describe as a yearslong trend of foreign nationals to exploit U.S. state laws that have legalized cannabis for recreational or medical use to produce marijuana for the illicit markets in the U.S.

The Drug Enforcement Administration is investigating international criminal organizations that are operating illegal marijuana grows in about 20 states, including Maine, Attorney General Merrick Garland told the Senate Appropriations Committee last week, in response to a question raised by Republican Sen. Susan Collins of Maine.
