WINDSOR, Ont. - Canada's self-styled "Prince of Pot" has come home to a raucous welcome from supporters in Windsor, Ont., after serving his U.S. sentence for selling marijuana seeds to customers across the border.

Marc Emery crossed back into Canada from Detroit this afternoon, and his wife, Jodie Emery, was among the crowd awaiting his arrival.

She says she and her husband are lucky that he is coming home a free man and can immediately resume their activism to legalize marijuana.

Dozens of supporters were lighting up joints and smoking pot with vaporizers as they waited for Emery outside Windsor City Hall.

Emery, 56, was extradited to Seattle in May 2010 and he pleaded guilty to selling marijuana seeds from Canada to American customers.

When Emery was first arrested almost a decade ago, the U.S. Drug Enforcement Administration heralded his seizure as a "significant blow" to the legalization movement.
