Smoking is out of favor and has been for years. Every year that goes by there are less smokers. Eventually there will be so few that the tax revenues don't matter anymore. I can't guess when that is coming though.

It was, but vape use has taken over, and once the nicotine addiction is in place people are open to smoking again.

Also, they tried taxing cigarettes to the moon in Australia and created a multi billion dollar black market for them instead.
