Marc Emery, a Canadian known as the Prince of Pot, and his wife Jodie Emery are due to appear in a courtroom at Toronto's Old City Hall at 10 a.m. ET to face drug trafficking, conspiracy and possession charges.
The Vancouver couple were arrested on Wednesday evening at Pearson International Airport while trying to make their way to a marijuana festival in Europe.
On Thursday, law enforcement officers in three Canadian cities raided various locations of Cannabis Culture, a chain of marijuana shops owned by the Emerys. Jack Lloyd, a lawyer, is representing the Emerys in Toronto.
