Cows are given drugs to produce 4 and 5 times more milk than they naturally do. All these drugs, hormones, and antibiotics go directly to the milk you are drinking. Due to this milk overproduction, the cows develop mastitis - causing the presence of blood and pus in the milk they produce.

So, yes, people not only are you drinking an animal's milk, which is already weird considering cow's milk is for calves, but you are also consuming a nasty mix of hormones, antibiotics, drugs, blood, and pus. Yuck!
