# Death by Caffeine Calculator

##### The times they are a-changin’.

This post seems to be older than 15 years—a long time on the internet. It might be outdated.

Quite a few years ago, I it was actually almost 4 years now, TheBS collected some 215 cans of Doctor Pepper to take on a three day retreat. We ended up drinking all 12 or so. I looked it up on the Internet and found there was 41 mg of caffeine in a can of DP. The LD50 of caffeine is around 150-200mg/kg. So, for a person having a mass of about 60kg, I would need to consume at least 9000mg of caffeine, or about 220 cans. Well, now that task is made much easier thanks to Death by Caffeine. Just put in your mass (either in lbs or kg), pick your poison, and DbC will calculate how many beverages of choice you need to consume to kill yourself. Of course, you would have to drink all the Doctor Pepper (or other tasty beverage of choice) rather quickly. With a half-life of around 5 hours in the average adult human body, you would have to be chugging those can pretty darn fast to actually OD.

1. “The LD50 of caffeine is around 150-200mg/kg”
huh?
What is LD50 and what are mg/kg?

2. LD50 is “the amount of a chemical that is lethal to one-half (50%) of the experimental animals exposed to it. LD50s are usually expressed as the weight of the chemical per unit of body weight (mg/kg).” (Source).

3. Hahaha that site is awesome…I can have a little less than 55 cans of rockstar before I die.

4. Is 100mg a day of caffeine too much ?? Thanks,Mark.
