This is Christy. She came to Tijuana in the late 90s for "the cheap drugs" and has lived here ever since. She told me that yes, she's an addict (heroin is her drug of choice; she shoots it in her neck) but that she's also addicted to Zona Norte. There's "always something going on", she says.
The tattoo on her chest says "Take a Chance on Me". She told me there is a free clinic nearby that will remove tattoos for people who want to start over. She said she's considering having it removed.
