How much is a lethal dose of espresso for an otherwise heathy 200 pound adult male?

Question

Is it even possible to consume this much without your body somehow rejecting it (by going to the bathroom, throwing up, ...)?

Answer 1

i would think you could get dehydrated by all the rejecting....

Answer 3

I think DukeFenton's answer is probably the best one, but I just had to comment on the username.  

May your Omni always be green.  ;-)

Answer 4

The LD50 for caffeine in humans is thought to be about 150 mg/kg; 200 pounds is roughly 91 kg, so a toxic dose would be about 13.6 grams or 13600 mg.  Given that a 2-oz cup of espresso contains about 100 mg, that's 136 cups, or about 8 1/2 quarts.  Most likely you'd be throwing up long before that point, from the sheer volume if not the stomach irritation.

Or, you could take 68 Vivarin, but the same difficulty in keeping them down arises - to say nothing of the expense.

Answer 5

Dukefenton has to get best answer - nothing else to add.

Answer 6
