People with mental illness who are in the criminal justice system can face several barriers to successful community reintegration. An example of a barrier would be:

A. Lack of a therapist can be a challenge, but it is not considered the primary barrier to reintegration. B. Being on probation is a legal status, not in itself a major barrier if support services are in place. C. Lack of a job can hinder reintegration, but it is often a consequence of broader issues rather than the core barrier. D. Substance use is a significant barrier to successful community reintegration, as it can interfere with treatment adherence, stability, and social functioning.
