I'm not sure which country you are in, but marijuana is legal in Canada (to the best of my knowledge) and about half of the states in the US (either "medical" or recreational).
Here in Florida where medical marijuana is legal, you simply go to a doctor who advertises to give you the "card" for medical purposes and tell him/her you have anxiety, headaches, or some other problem and pay about $100. You walk out of the door with the card and can buy and use whatever you want.
It doesn't surprise me that so many people use it on the weekends, much like watching a football game with some friends and having a case of beer.
But I would guess that smoking some weed during a football game has a more calming effect than guys throwing beer cans at the TV when the other team scores.
