Start with the verified service context
The dual diagnosis program explains the relevant MVBH service context. MVBH admissions is the linked route for questions about MVBH processes. These resources serve different purposes: one supplies program context, while the other supports direct next-step questions.
MVBH describes dual diagnosis treatment in Amesbury, Massachusetts, as integrated care for adults with co-occurring mental health and substance use disorders. A supporting definition says co-occurring disorders means the coexistence of both a mental health disorder and a substance use disorder.
That scope makes the two-domain question relevant. It does not establish that ADHD is present, characterize stimulant use, or determine whether either concern meets any clinical definition. It also does not show that OP is the applicable program for an individual.
The practical use of this overview is narrower. First identify whether the decision actually concerns both mental health and substance use. Then compare the verified purpose of OP with the question at hand. Keep those steps separate from decisions about personal needs, program entry, or expected results.
