Gotta walk before you can run. Still a long way to go in America towards treating addiction as a health issue, not something to be locked up in prison for. Prove effectiveness and then make your case for more funding.

Even if most of the money comes from the general budget, that still would be a huge saving compared to trying and incarcerating them. Whether it's paid for is the big question.

Is that a speculatuon or do you know / have data for how much is needed? Can you tell us at least roughly what percentage of expence will this revenue cover?
