I was totally addicted to eating chalk. Not exactly chalk but another harder form of it used to write on slate. I absolutely love the smell and taste of it. I’ve been addicted to it for around 7 years. I used to eat it all the time all day long. It took me great will power to get over the addiction all by myself. Now I keep a few pieces of it with me just to smell them and feel the extacy :)
I would say you can try it, but dont get addicted to it.
