There are people that are able to live on benzodiazepines long term without significant health impact. There are a lot of medications that are suitable for a lifetime of use in the SSRI and anti anxiolytic family that do not have the potential for habit forming either (and that's habit in the sense of your body becoming accustomed to it).

It's great that you're concerning yourself with the well-being of other people, but please allow concern over the use of medications to be between people with significant mental health issues who are taking those medications and their doctors.
