While marijuana is legal in the Bay State, it’s still illegal to move massive amounts across state or international lines.

That’s the message from police after yet another person has been busted for allegedly trying to transport a huge amount of weed through Boston Logan International Airport to the United Kingdom.

A 19-year-old London woman was arrested after U.S. Customs and Border agents seized about 70 pounds of marijuana before her flight back to the U.K., the Suffolk DA’s office announced on Tuesday. The 70 pounds of pot is worth about $350,000 in the U.K., where marijuana is illegal.

Fareedat Folunsho is now the second passenger flying to the U.K. who was arrested at Logan for trafficking marijuana in the last two months. Previously, a Michigan woman was arrested at Logan for allegedly trying to transport 74 pounds of vacuum-sealed marijuana to London.

Folunsho has now been charged with trafficking marijuana between 50 and 100 pounds. A judge ordered Folunsho held on $1,500 bail, and to surrender her passport.

At about 9:30 p.m. on Sunday, a Massachusetts State Police trooper was dispatched to the U.S. Customs Hall for a woman in custody, later identified as Folunsho, for trying to fly back to the U.K. with the marijuana.

Marijuana in the U.K. has an illicit-market street value of about $5,000 per pound.

“These two arrests in a fairly short time span should make it quite clear to anyone else trying to fly marijuana to the U.K. through Boston that it’s not a good idea, to say the least,” Suffolk DA Kevin Hayden said in a statement. “It didn’t work for these two women and it’s not likely to work for anyone else either.”

Folunsho is scheduled to return to court on May 21 for a probable cause hearing.
