We wanted rid of Harper, that is fact, but it didn't anything to do with his policy on weed?! There was not really anyone else to choose from either.
Not sure where you got the 5 year thing, but that has nothing to do with smoking in your home or outside or even simple possession! Been there done that more than once.
