I haven't experienced this, though I am sorry you had to.

I wonder if you have seen the show 'six feet under'? In it, one of the characters gives a ride to a hitchhiker and the hitchhiker does the same thing to him, holds him hostage and essentially tortures him. During it, he makes him smoke crack. I don't know if it would be triggering to watch or worth watching for you. It was a pretty traumatic show, and the subsequent shows were him dealing with obvious PTSD surrounding it.
