Example Interview Questions.

Provider Healthcare Setting	Every clinic works differently and is comprised of different team members. Can you please share a little about how the clinic in which you provide HIV care is constructed and functions?
Approach to tobacco and cannabis use	How did the presence or availability of support staff (eg, mental health providers, peer navigators, etc.) impact your discussion?
Approach to co-use of tobacco and cannabis	Think back to a recent clinical encounter in which you discussed tobacco with an 18-24-year-old living with HIV who used tobacco and cannabis. Can you tell me a little about the conversation, who started the discussion, how well it went, what prompted you to talk about the individual's co-use (both tobacco and cannabis) at this visit?
How the approach to tobacco and cannabis cessation varies by population	How did this discussion differ from discussions among different populations? Young people not living with HIV? Older adults (30yo and older) living with HIV?
