"they're banning nicotine products" If I am not mistaken, they are banning to sale of tobacco, not nicotine:

"[..]provision prohibiting the sale of tobacco to people born on or after 1 January 2009[..]"

"I also really doubt that they will legalise weed and then say "but of course you're not allowed to smoke it, edibles only"."

I mean, there is still vaporization, so it wouldn't be edibles only?
