I am not a doctor but i did a little snooping around on the internet, the tim hortons website, and redbull website and can. That tim hortons your sipping on has more caffeine and sugar than a regular sized can of redbull. One small cup of coffee has anywhere from 85 or more mg of caffine. While a can of redbull has 80 mg of caffeine. So all those advocates against redbull, can suck it. This does not on the other hand include drinks like nos, monster, and rockstar. So sorry guys.
