I haven't read anything disrespectful towards PH, at least not in recent pages where I began following again. She had a VERY serious addiction, which was public knowledge. Every addict I have known who is clean admits it is a daily battle.
She sent a text, or texts, to a friend. She was fearful, BUT if she was being kidnapped, totally against her will, wouldn't hitting 911 have made more sense? Or even texting "OMG, help me!" And why text the friend unless she still at least partly wanted to be out wherever she was, but just felt a bit like "Hmmm....maybe I should let some know this could be getting weird?"
Drugs FIT as POSSIBLE explanation/motive for willingly leaving with FH, and/or the HSBM AND for the tone of the text. She thought they were going to get a quick high, maybe go back to the bar, and something else happened instead.....
The high may not have been heroin or hard drugs. PH could have been offered something more benign like pot. It's not legal in Alabama, is it?
I had friends when I was young who bought pot from incredibly scary dudes. Scared the cra p out of me. They thought nothing of walking right into a rundown inner city apartment, at 1am as a dumb little college girl to grab their drugs. No idea how they didn't end up dead or worse.
