If one needs a reason to get angry, it isn't difficult to find. High amounts of caffeine is a personal catalyst for starting the reaction, though it's more like lighter fluid than the match itself.
There are longer-term drawbacks I've found. The benefits last for a short amount of time. Within the confines of an hour, at best. After that, feelings of aggression remain as well as the inability to think straight on a conscious level. The subconscious will stop picking up the slack as well, unfortunately, so you become an easy target.
