Well, according to science it is physically addictive. However, many people probably are not addicted to it. I happen to have to keep an eye on myself because I have a very addictive personality and just cut out booze and smokes. Mind you I am also referring to large amounts of refined sugar. People need a bit of natural sugar in their diet. :) But it has gotten to a point where people eat massive amounts, and their brainsdo react to it the same way they would to hard drugs. You can click the link in my blog where it talks about that and it'll take you to some studies. :)
