Highly caffeinated alcohol drinks

Highly caffeinated alcohol drinks are being linked with dangerous levels of intoxication and violence. Health professionals say the popular drinks, either pre-mixed or cocktails, mask the effect of alcohol and create `wide awake drunks.' The Federal Drug Administration in the US says it may ban the pre-mixed versions of the drinks and in Western Australia one bar has already been banned from serving alcohol mixed with energy drinks between midnight and 2am.
