The origins of '420' as a numerical code for smoking marijuana are quite unclear.
However, some believe it started with a group of high school mates in 1970s California, who met at 4.20pm to smoke pot after classes.
Canada celebrated the first 420 Day since the nation legalized recreational marijuana at the end of 2018.
