Confidentiality and Substance Abuse Information

Imagine that you are a human services professional working with an adult client who is seeking treatment for a substance abuse overdose.

Explain at least one way that the limitations under 42 CFR Part 2 for disclosing substance abuse information impact effective information sharing for all parties involved in this scenario.
Indicate what might be different if your client was a child and had a parent or guardian. If the patient is a minor, how do you ensure provisions under 42 CFR Part 2 are abided by?
If your client has threatened someone, how do you determine if there is a duty to warn those being threatened?
