Hi everyone, I've got a question. I'm currently studying psychology which was my academic entry choice because a year ago I still didn't know how I could monetize my interests in the human mind and behaviors. Recently I've been doing research on addiction therapy, and I came across this article: https://addictionresource.com/treatment/milieu-therapy/ and I got really interested because that seems like it could help people on a larger scale (I'm currently thinking- addict cities, a bit excessive I presume) than one-on-one therapy. It also touches other areas I'm really interested in - sociology, a bit of logistics. So here's the question: has anyone had any experience in this field, heard about this type of therapy (I believe it's different from what most rehab facilities propose), and possibly does anyone have a second degree proposition? Thanks!
