Come on, now. Of course it does. Sound exists in spite of ears. Microphones and sound recorders proved that long ago.

Absolutely. If it supports or even suggests the slightest possibility that you might drink or use, ever, then it is addictive voice. All addicted people have AV thoughts, but they don't always perceive them as such. The whole point of AVRT is to perceive. AVRT is kind of like night vision -- it turns on the lights, and suddenly you can see the AV lurking in the dark.

AVRT is not that deep.
