Canada's so-called Prince of Pot, who sold millions of marijuana seeds to U.S. customers before his 2005 arrest, has been sentenced to five years in prison after earlier pleading guilty to a drug charge.

At his sentencing Friday in U.S. District Court in Seattle, Marc Emery told the court that he "arrogantly violated U.S. law."

Extradited from Vancouver, British Columbia, in May, the 52-year-old pleaded guilty to one count of conspiracy to manufacture marijuana.

On his website, Emery claimed to have made about $3 million a year selling seeds and to have sold more than four million seeds over the years.

U.S. Attorney Jenny Durkan says Emery "sold to anyone who would pay him — with no regard for the age or criminal activities of his customers."
