By law ff the person is an adult they have the right to refuse treatment regardless of if they believe they don't have a problem or have been officially diagnosed. There is no way anyone can FORCE the person into treatment or to follow that treatment program until they have been deamed a threat to themselves or others. So basically if the person is an adult there is very little that you can do. In fact the only thing you can do is wait until the person is a danger to themselves or others and then during the dangerous situation call the police, they will transport the person to the local ER for an evaluation. That person will have to be seen by 2 on staff psychiatrsts. Those two will decide if the person is well enough for release or should be held on the mental health unit for a 72 hour observational evaluation. At the end of the 72 hours the MHU treatment team decides if the person should be released or committed to the unit for 14 days. At the end of 14 days the treatment team decides if the person can be released or they are sent to a longer term facility until they are deamed no longer a threat to themselves and or others.
