People who haven't had their coffee fix in the morning are not anti-social? And if they have to wait to long (which gives headaches and an overal feeling of malaise in heavy coffee drinkers) they tend to get something I would call violent in the context of an office working environment. Still, making something illegal never helped and moderation is not something most humans are good at. Everything is addictive and can cause anti-social behaviour (gaming...) and violent or dangerous (for themselves and/or their environment) behaviour up to some extend.
