Smoking will continue, but I suspect that many people will choose to consume via edibles/oils/etc which won't have a smell, or vaporizers which also have minimal odour.
When the dispensaries popped up all over Toronto (pre-raid) there were MANY edibles, so I assume they were popular. Sadly, after the raids the dispensaries switched to /just/ flower and concentrates. One can still order concentrates and edibles online however.
