The film is set in Washington state (witness the car license plates), but when Ig drives into town near the start of the movie, we can see a branch of the Canadian Imperial Bank of Commerce on the right side of the street.
When Ig tells his brother Terry to swallow all his pills, Terry puts a few in his mouth and uses the little bit of liquid in his glass to swallow them. There shouldn't be any liquid left after that. In the next scene with Terry, the glass is full as he swallows more pills.
