I am just adding my perspective, this may or may not be true, but for most part it makes sense.
In the episode ‘The Thin White Line’, where Brian gets addicted to Cocaine, after several days of addiction, he brings home a girl named ‘Tina’.
Now, ‘Tina’ is one of the street names for Methamphetamine. Also, general progression of addicts is that after Cocaine/Heroin, they progress on to using Meth. Meth users lose weight and are usually skinny, and so is the said girl in the picture.
This must be such a well thought-out scene.
I wonder what more references I’m missing out while watch the show because there seems so be so much depth in each and every frame.
