In Poland there's a tax for both sugary and artificially sweetened drinks since 2021. Also caffeine and taurine. In one year the effect for beverages over all was 36% raise in proce and 20% drop in sales. Surprisingly sales of energy drinks rose by 4%. Caffeine drinks can't be sold to non-adults now so that probably dropped too. In two years 60% of beverages altered their ingredients. Tax income was less than you expected.
