> I know one person who says of herself that some days she just can't go into the city. Because she knows on those days she'd get hooked again if she were to pass a place where she used to shoot.

If one can opt out (by eg not going into the city), one can also opt in.

Looks like you wanted to build an argument but lost steam after one sentence. Here, let me continue for you: "So if she chooses to go to the city, it will be her decision and consequently her responsibility when she inevitably gets hooked again."

Oh but you see, it's her friends that give her the freedom not to go to the city: If they weren't there, she wouldn't have that choice.
