I’m of two minds of this. While I know that prohibition laws haven’t succeeded in the past, I also know that nowadays people don’t complain that coca cola doesn’t have cocaine anymore. It’s a harmful substance that was legislated out of being so easily accessible.

Also, with the trend towards fewer younger people smoking altogether it seems as though introducing it in this way to make it so that young people might not see it as an option makes sense to me, although maybe it’s optimistic of me to think so. The idea that smoking is already seen as an “old person” activity and efforts taken to minimize its attractiveness to youth, now following that with legislation, seems to make a logical sort of progress.

That said, I understand the black market is always going to be a thing. OP put it really well though- when something is designed to be addictive you’re already having your choices removed by being pushed to use it. If the availability is minimized, then hopefully the number of those who depend on it will also be minimized. I’m glad it’s being trialled somewhere, and am interested to see how it goes- though also hope if there are negative repercussions these legislative changes can be changed or rolled back depending on what those consequences look like and/or merit.
