FY 2012: The SAMHSA budget authority was $3,386,903,000
FY 2024: The President's Budget Request was $10.8 billion, an increase of $3.3 billion from the 2023 Enacted level.
That's about 9% increase every year. These programs didn't always exist and they have grown considerably over time while addiction and mental health have both gotten considerably worse during that period. I think it's worth re-evaluating to see if these programs are doing anything.
