baby formula and cocaine

Today I learned that powdered baby formula is a target for thieves because a 25.7 oz (0.73 kg) can goes for $25. Besides its worth as food, apparently drug dealers find this substance useful for cutting into cocaine. You know that made me wonder what people usually cut into cocaine, so I went out and found this list that specifically mentions Italian baby milk powder, which, even accounting for British English, makes me wonder if the list makers know what the heck they're talking about, unless Italian baby formula has some gourmet quality I don't know about. I'd have thought preferred cutting substances would be cheap, like baking soda or sugar, but I'd likely make a lousy drug dealer.
