Check with your local courthouse. I live in Florida and I had my husband Marchman acted (similar to the Baker act, but for drugs and alcohol).
The Marchman act is a 2-step process. First, you file a petition to get the addict into detox for assessment. The next step is to file a 2nd petition for the addict to get treatment. The whole process is involuntary. The same day I filed the first petition, a deputy immediately picked my husband up (involuntarily) and transported him into detox for 5 days.
Check with you local legal system. Good luck.
