Heartbroken parents have sued an alcohol company. They say their son died after drinking what some have nick-named "blackout in a can" and "liquid cocaine".

One can of the drink Four Loko packs a burst of caffeine and a ton of alcohol. A 15-year-old apparently drank two cans of the stuff before he died. One can of Four Loko is like drinking five beers and four cups of coffee. This teen had the equivalent of beers and eight cups of coffee the night he died.

Phusion Projects, the makers of Four Loko, has since removed the caffeine from the drink after the FDA insisted it be taken out.

Watch as Dr. Drew takes a closer look into this tragic story.
