so i am planning to do a short doc about meth drug use and im filming a person and i was gonna more than likely want a scene of her using or prepping ..is there any legalities around this. anything i should be concerned about when showing the identity and showing the drug use since its illegal drug use. i see docs like this all the time and think why dont the police just hold up the camera crew and make bust. wasnt sure if there is some special situation or release form for this
