A perscription, schedule III, narcotic analgestic (pain killer) containing hydrocodone and acetaminophen (Tylenol). Hydrocodone is actually an opiate, like heroin, that gives an amazing euphoric body high but it's also very addictive (although not nearly as addictive as heroin).
Unlike basketball and football, there is no way of knowing how long a game of volleyball will be. Like the others have already said, whoever wins the first 3 out of 5 sets wins the game. How long that can take can be anywhere from 30 minutes to 2 hours. (I've played in both).
The official length of the volleyball court is 59 feet or 18 meters. In terms of width, every court must measure 29.5 feet or 9 meters. The court is divided in half by a net. Each side is 9 meters wide and 9 meters long.
