Sugar More Addictive Than Cocaine
In the experiment, 43 rats were placed in cages with two levers, one of which delivered an intravenous dose of cocaine and the other a sip of highly sweetened water. At the end of the 15-day trial, 40 of the rats consistently chose saccharin instead of cocaine.
Sure, it's rats. Hard to know how much this correlates with human experience. But for me at least (and I know I'm not unique) sugar is a powerful addiction. I haven't had any first-hand experience with other addictions, but I know I've been unable (so far) to kick this one. I've gone for stretches, but never more than a few weeks, and usually never more than a couple days. Binges are rare, but also happen. I'm very well-informed as to how harmful it is, and yet I rationalize, cave, etc. It's an addiction, just like any other. Alcohol, tobacco, sugar, coke, what have you. They all hook you hard, they're all bad for you, and, insidiously, they all (generally) kill you very, very slowly, so you can build a (shortened) lifetime out of saying "just this once...", "I've been good", "I'm depressed", "it's not that bad", etc.
