In my experience, through the work I've done, all survivors are different. They all have different needs, routes and services that they think are best for them.
I will say that the majority of the women I have supported prefer to be abstinence-based and to go into sober living environments. They find it harmful to live in harm reduction spaces. However, there is a need for harm reduction spaces, as well, for those who aren't ready for sober living just yet.
