I suspect in a few decades forced rehab will become the norm, once you start smoking crack or shooting up in the street. It's pretty obvious for anyone with eyes that at a certain point, homelessness, mental health issues and most importantly drug addiction cannot be covered by "individual freedom" anymore if you want to have a working society.
Of course, having police beat up and arrest or otherwise forcefully move addicts from one place to another or into the prison industrial complex is not likely to work.
