Carmen is a girl who is alcoholic (Lana obviously) but the symbol of Carmen through the song becomes a symbol of crystal meth or methamphetamine. You can see in the chorus, it's really simple.
"The boys, the girls, they all like Carmen'' - all her friends like and do meth
"She gives them butterflies" - meth helps the release of serotonin (a hormone contributor to well being and happiness)
"Her mind's like a diamond" - diamond = crystal
"Like lighting, white lighting" - obvious
If you watch the Carmen video closely, you can see that the some parts of the video show for a second how methamphetamine affects the central nervous system and the release of serotonin.
