All I can tell you is that in the US, such a program would be abused to the point of absurdity. We already use the "war on drugs" to create an army of millions of unpaid workers through various prison industries programs. We lock them up, then low security inmates are used for cheap manual labor outside their prisons by local businesses (yep, these programs are in place in a number of states). Higher security inmates work in metal and other shops built on prison grounds, but their work is exported to outside businesses.
In short, our government and the corporations that control it are far more evil and greedy than anything you would find in Switzerland. A program like this on US soil would in fact be turned into modern-day slavery, and because of the stigma associated with drug addiction, these abuses would be embraced and encouraged by the US populace.
Here's an example program in Colorado: https://www.coloradoci.com/
