Query: An outstanding, realistic movie

"Traffic" is one of the most realistic portrayals of the drug war I've seen yet on the big screen. I am in law enforcement working in the Narcotics section. If anyone cares to see what drugs really do to a person, starting from the lengths drug addicts go to get their drugs to their behavior on drugs and the vicious addiction cycle, this is the movie for you. The movie achieves a good balance in portraying how supply and demand work together equally to further the problem. Without giving away the ending, "Traffic" depicts just how frustrating and complicated the drug problem is for both the addict and for law enforcement. This movie is a must see.
