Sales of sugary drinks fell dramatically across five U.S. cities, after they implemented taxes targeting those drinks – and those changes were sustained over time. That’s according to a study published Friday in the journal JAMA Health Forum.

Researchers say the findings provide more evidence that these controversial taxes really do work. A claim the beverage industry disputes.

The cities studied were: Philadelphia, Seattle, San Francisco and Oakland, Calif., and Boulder, Colo. Taxes ranged from 1 to 2 cents per ounce. For a 2-liter bottle of soda, that comes out to between 67 cents to $1.30 extra in taxes.

Kaplan and his colleagues found that, on average, prices for sugar-sweetened drinks went up by 33.1% and purchases went down by basically the same amount – 33%.

    Soda is a real money maker too in fast food. That 32oz drink you are paying $2+ for only costs the restaurant 8-10c? And most of that is the cup.

      I know gas stations are a 300% mark up on fountain pop. At least thats what it was back when i worked in one like 15 years ago.

    Which is what the beverage companies were afraid of so here in Washington they spent millions lobbying and lying to get it banned from happening outside Seattle.

    It was eye opening the first time we flew to Europe. The first convenience store sold few sodas, mostly different types of water. And the soda they did sell was more expensive.

    We tried an orange soda. It was less sweet and tasted far better.

      Orange soda is odd in Europe. In Europe depending on region has a varying percentage of real orange juice. In the US its 0% juice naturally

      In the Netherlands bottles of water and soda cost pretty much the same. Unless you specifically ask for tap water in a restaurant, then it’s generally free.

      Grape juice is my favourite, especially the fermented one. A bottle of decent one is about $5-10 in a supermarket in Spain.

      The supply and demand curve is about how those two determine the price. With the tax, we are talking about the price “controls” affecting the demand, not the other way around.

      And, additionally, even if we think the outcome should be obvious, it’s always important to do a structured objective analysis to see if that was actually the case because, if it wasn’t, it’s time to revisit the theory or figure out what went wrong.

        you can model the tax on the supply or the demand. in most simple models the outcome is the same

          Maybe you can, that would make sense. But it’s really neither supply nor demand, so it’s just forcing it into the model, which you’ve now made more complicated and no longer the simple curve that the op was suggesting it is.

      The argument would presumably be that demand is highly price-inelastic. Which seems ludicrous to me for soft drinks, but you could try making the argument if it was in your interest to do so.

    Over here a 16 oz bottle of soda can be close to $4. I’d rather buy 64 oz bottles of juice on sale for $5 or less and water it down.

    What about sales in cities near these? I doubt people will stop buying it just for the tax, I bet they are willing to go elsewhere to get it for cheap and just by in bulk.

      In the first part, findings, it says this:

      " In this cross-sectional study, SSB taxes in Boulder, Colorado; Philadelphia, Pennsylvania; Oakland, California; San Francisco, California; and Seattle, Washington, were associated with a 33.1% composite increase in SSB prices (92% pass-through of taxes to consumers) and a 33% reduction in purchase volume, without increasing cross-border purchases"

      So there wasn’t an increase in sales volume in other areas (cross borders).

        Nice, then good to know!

        What I was thinking is people need to be aware of the serous health issues from drinking a lot of soda to ease down on it but I guess any steps that help reduce its consumption are great.

          A lot of people think “ah Ill nab a soda on the way, its only $2”

          So when its “only” $3.50, $4.25, $6, it gets a lot harder to make those passing “ah fuck it” purchases while youre out and about doing other things.

          Its not like alcohol, where you make a point to obtain it for a designated drinking time and so will go out of your way to fulfill an errand. Its a passing convenience that you do less often when it becomes less convenient

            Sadly there is also a lot of people who buy it regularly. Was just with some relatives over the holidays and they have full stack packs of coke for the day to day.

            This segment is who I would think go out of their way to avoid the taxes.

            You bring an excellent point and probably it is in that segment where the reduced consumption is when the taxes are higher.

      You’re really driving the next city over to get soda pop? Or are you more likely to just drink less and maybe pick some up if you remember?

        I know a few people that drive 45+ minutes to get to a Wegmans because it’s an “experience”, so I wouldn’t put it out of reach for someone to go across town lines for soda (and other stuff) if you consume a lot of it.

          People be wacky, but on the average most folk won’t do that.

          Generally diet or “zero” versions of soda were tax exempt because they dont have sugar, so that’s most likely what people moved to. Still likely a net health win.

            Not when Cook County did it in Illinois. Zero sugar/artificially sweetened drinks were taxed at the higher rate, yet sugary fruit juices got a pass. I live on the border of Cook and Will county, so I just shopped at grocery stores outside the country. I’m not sure how long it was in effect, but they ended up cancelling it.

      I’d bet single serve is a pretty serious portion of soda sales. Restaurants (especially fast food) and gas station/convenience stores sell a lot of soda.

    I’m more curious about how it affects the sale of other drinks and foods.

    Do fast food sales drop because of the increased cost of their primary drink options? Do people turn to water as an alternative or do they fill the hole with another option like alcohol, tea, or coffee?

    • @yamanii

      Soda at fast food is already triple the price though.

    I encourage everyone who likes sugary soda to at least try flavoured sparkling water. Personally I have replaced nearly all my soda intake with it, and the fruit flavored ones are surprisingly sweet without any sugar or artificial sweetener, and I imagine are way healthier than even diet soda. If you find that you like it, getting a sparkling water machine like a Soda Stream is also more environmentally friendly and more cost effective if you drink a lot of it as well.

      I like both but they definitely aren’t interchangeable for me.

      When I want a seltzer that’s what I want and a coke is too sweet.

      When I want a coke, the seltzer isn’t sweet enough.

      That being said, one of the few healthy changes I made and stuck with was after making my most recent move 6 years ago, I just didn’t buy 2L bottles of soda to keep in stock in the fridge.

      Didn’t boycott them, didn’t avoid them in restaurants or convenience stores, and I still keep a few baby cans as mixers in the bar at my apartment, but in that list of things you just get when you run low to keep a stock…I just kinda took soda off that list.

      Found that I only really missed it a few times a year, and if I was really craving it, I could go get a little can from the bar…but just that one small change probably cut my soda consumption by like 85% and I barely miss it.

    So do 100% orange juice/grape juice have the same taxes? Because these are just as sugary, if not more so, than soda. Sugar is sugar, doesn’t matter the source. If they’re not taxed the exact same way as soda, then this is a bullshit tax that shouldn’t survive a challenge in court.

      I’m not a fan of juice for the reasons you point out. But soda provides pretty much no nutritional value, it’s just pure sugar. At least with juice you get some other nutritional benefits. . .although, you should obviously get that from eating it and not drinking it.

      But I think the tax laws are, generally speaking, if they don’t include juices, are for drinks with added sugar/sweeteners which would exempt 100% juice. This would probably pretty easily hold up in court.
