You can have a look at some places that implemented the policy you’re putting forward to check if it works though, right?
Have a look at Australia & New Zealand. Taxed at around 65-70% respectively with intent to make cigarettes cost prohibitive
A summary of some outcomes following a decade or so of implementation of these policies:
No acceleration in the overall decline of smoking rates at any stage following policy implementation
Reversal of trend in Australia where tobacco use is currently increasing
The disproportionality in smoking rates between Europeans and the countries’ respective indigenous groups is now higher
Politicians (even the health minister himself in Aus) now champion increases to tobacco excise as a means to secure the financial stability of the country
All this while cost of living increases, rate of poverty increases. I mean not all of these things are solely attributable to periodic tobacco excise increases but it hasn’t fixed a thing. The government got some more money to blow on some antiquated nuclear submarines to defend our massive island, surrounded by allied nations and thousands of miles from the nearest potential adversary. They’ll be ready in about 20 years. Great to see the extra tax dollars at work!
