[ELI5] When and how does money taken by the police for evidence re-enter the economy?

Edit: To clarify, I'm talking about money that is taken because it was used in the selling of illegal goods. Not money taken because it may contain DNA.

For the most part, police departments get to keep money seized by forfeiture, which is why it's such a huge problem. The departments then spend it on whatever they need: weapons, parties, dogs, cars, personnel, etc.
