How would 1) a soldier in the middle of Vietnam go about buying/using heroin? Where could he buy it in between fighting? For how much? Would he use it in front of the other soldiers, or in privacy (if so where)?
And, then, 2) what would the situations be for a die-hard, school-dropout Vietnam protestor who used LSD and marijuana? How would she get her hands on some, and for how much? What would the conditions be when she'd use it?
Thanks for the help!
