Are Carbs more addictive than Cocaine?

I love this article and it touches on some of the points that i made in one of my earlier posts here.
I've spoken to many people about the addictive qualities of Carbohydrates and particularly grains and dairy. I even had one friend who tried to go Paleo, but suffered immense headaches and gave up after just a couple of days. This friend is definitely a sugar girl. She loves her chocolates, her breads, and her lollies. Hmmm, withdrawal symptoms anyone?

Check out the article here:

This is a quote just to get you thinking:

"In 2007, researchers at the University of Bordeaux, France, reported that when rats were allowed to choose between a calorie-free sweetener and intravenous cocaine, 94 percent preferred the sugar substitute. The researchers concluded that "intense sweetness can surpass cocaine reward. . . . The supranormal stimulation of these receptors by sugar-rich diets, such as those now widely available in modern societies, would generate a supranormal reward signal in the brain, with the potential to override self-control mechanisms and thus to lead to addiction."
