The current excise policies were implemented around 2010, at which point the global decline was already well underway. As I mentioned originally, there has been no stage following implementation of the respective policies in which the decline in smoking accelerated. It has only slowed since that time, and in Australia is increasing as of 2023.

It’s unreasonable to assume that allocations of tax contributed by smokers and tobacco companies is proportionately allocated to areas relevant to the stated intent of the tax policy.

correlation isn’t causation

Do you think these are magic words or something? The entire stated intent of the policy is to cause a correlation that is inverse to the one that’s been observed since. Nowhere above did I say that tobacco excise causes the problems I mentioned - I responded to someone putting forward the idea that it is a viable solution to those same problems. I have trouble considering your response to be in good faith, since I already disclaimed this in my original comment.
