Other than that, the poison is always in the dose. But, cocaine? I think not. There is no evidence that biochemical pathways of sugar in the human body include the manufacture of a highly addicting compound - as does cocain. But, there is and has been for decades and decades clear evidence that most things in the human diet contain sugar that will be injested as, or broken down to glucose and fructose...and a few other sugars. If sugar is as bad as cocaine, one would have to eliminate bread, fruit, and a lot of other "staples" from their diet, leavng little more than an Atkins type diet.
