The way I implemented this strategy was to make sure I had a single cigarette and lighter on me at all times. I named the cigarette, which psychologically helped prevent me from smoking it. I stuck that out for a few months until a friend smoked it in desperation. At that point I felt confident I’d quit because I wanted to, not because of random circumstance.
I think it’s a step in the right direction, though it will be interesting to see where the boundaries are drawn. Does YouTube count? What about gaming platforms like Roblox and Fortnite?
Edit: On further reading about this, I’m changing my mind. I can’t see how this would be implemented effectively without some kind of age verification. Unless it’s a meaningless Steam-style “What’s your birthday?” question, that makes it far more troublesome for everyone’s privacy. I can’t see how it would get off the ground after so many Australians have had their data stolen already.
