The Caffeine Examiner is a review site that perhaps thinks about tachycardia-inducing products a little more than is healthy. Indeed, it’s just released it’s list of best caffeine products of 2008, voted for by the readers.
In fact, they have awards for 2008’s best energy drinks, best energy shots and best energy products.
Just looking at the names is interesting enough, with products called things like Spike, Bomba and Cocaine (pictured).
Interestingly, the site also lists the strongest energy drink, called Redline Rush, which has 500mg of caffeine, the equivalent of 6 1/2 shots of espresso, and has a health warning the size of a small essay.

Caffeine is the most abused psychotropic drug in the United States, and is as addictive, if not more so, than other stimulants that are illegal. Most consume caffeine so much, it is believed, to self-medicate for depression.
Speaking of stimulants, Ritalin, the ADD drug, is biochemically identical to cocaine, only slower acting.
