The psych ward here, well, the one in Asheville where I was adamantly welcome for nine days lol, they kept you medicated. I had switched to bupe and was buying on the street when I got committed. Told them as much, told them what I was taking daily and they titrated me up to that over a couple days. This was recently, this year. But yeah, walked out of there with a prescription and a referral to a free community clinic that actually did take homes off rip for suboxone, instead of daily dosing. It's far from perfect and not the permanent state they try to push it as, but it is getting easier to do a more practical MAT in some areas.
The whole time in the psych ward, though, minus the first day, I got 4mg sub twice a day, hydroxyzine, ibuprofen and prn nicotine gum.
