An internet computer game has been condemned as being as addictive as cocaine after a teenager who played it 24 hours non-stop had convulsions. World of Warcraft has been hugely successful in capturing the imagination of players by drawing them into a virtual universe of battles and quests.

'For those, the consequences are potentially severe. 'Such prolonged gaming can produce a sort of socially withdrawn figure who may be connecting with people in the game, but is largely dropping out of education and other social opportunities.' --------------------------------------------------------------------------------------------- The warning comes after a Swedish boy of 15 collapsed after playing it for for 24 hours earlier this month.
