Christine Roberto PhD .et al
In 2017 a study was done to examine the effect of raising the fee in both sugar and artificially sweetened drinks. Two cities were involved, mainly Philadelphia and Baltimore. The study included supermarkets, pharmacies and general mass merchandisers. Altogether the number came to 291 places.
The researchers concluded that the prices ended up higher in Philadelphia while the quantity of drinks that were sold went down. However, the number of sales in stores outside Philadelphia went up.
