Sit-in at PM's Calgary office

Pro-pot protesters staged a sit-in inside Prime Minister Stephen Harper's Calgary constituency office Wednesday afternoon.

About a dozen demonstrators took part,  including the wife of Canada's so called prince of pot Marc Emery.

They're sounding off against the justice minister's decision to extradite Emery to the U.S. for selling cannabis seeds from within Canada.

Demonstrators were asked to leave the office a few times, but each time they steadfastly refused, saying they have the right to occupy a publicly-funded office.

Two protesters who are legally allowed to smoke pot for medical purposes, rolled joints inside the office, but didn't smoke them.

Marc Emery's wife Jodie says they are taking this step because writing letters and signing petitions is not working.

"Now it's time to step it up peacefully and occupy a space we own," said Emery

Protesters also chanted while waving flags that said "Free Marc Emery."

Four similar protests were held at Conservative offices across the country Wednesday.
