Because they want the money. The reason drug crimes are so heavily enforced is because they come with large fines and fees and monetary rewards for the department that arrests them and the courts that prosecute them. They use it as a funding source. Look at what fines and fees a court gets when they successfully prosecute a murder versus a drug crime. Look at the grants the feds give towards police drug enforcement departments. DHS wants that easy cash.
