A man smokes marijuana outside Windsor City Hall during a gathering to welcome back marijuana advocate Marc Emery (not seen) who is released from an American prison for selling marijuana seeds in the U.S., in Windsor, Ontario August 12, 2014. Emery jailed for five years in a U.S. federal prison for shipping marijuana seeds across the border returned to his homeland on Tuesday, as laws regulating the drug in both countries have slowly been relaxed.
