The consequences of consuming too much sugar (obesity, diabetes, chronic inflammation, adverse cognitive effects, etc.) are already well known. Therefore, it does not follow that adding a few cents (or even a dollar or two) to the consequences will dissuade people who overly imbibe in sugary sodas.
These are obviously people who are seeking the "drug" of sugar and are not thinking of any consequences, physical or financial.
Wendy Richardson, ADHD expert and author of "When Too Much Is Not Enough," talks of sugar as being the "gateway drug" for kids with undiagnosed ADHD (sugar being more available to children than are cigarettes, alcohol, etc.) And some continue their habit for a lifetime.
In a certain way, sugar acts a a stimulant to the nervous system. These people simply feel better when they consume sugar; some might even think more clearly. At least for the short term. Then of course the glucose roller coaster begins.
So no, I can't see that taxes (unless they are absolutely exorbitant) would make any difference. But I do agree with Brendan: Selling soda in the schools is a very bad idea.
