Can you overdose on crack cocaine

I am writing a book about the city life and drug addiction. I am running into some writers block because I shooting for the stars and attempting to write a portion of my book about crack cocaine addiction. After living in a big city all of my life, I have that part down straight, but writing about something I have only experienced from an outsiders perspective is proving to be a challenge. To spice things up a bit, I need some details about crack cocaine addiction and abuse such as overdose. Do crack cocaine users usually overdose on the drug or perhaps have a shorter life span?
