Kafija
The LD-50 (lethal dosage that would kill approximately 50% of the population) is 10 grams of oral administration. This is equivalent to approximately 100 cups of coffee, or 50 Vivarin pills. One exceptional case documented survival after ingesting 24 grams of caffeine. The minimum lethal dose of caffeine given intravenously was 3.2 grams.
While coffee drinkers often have caffeine blood concentration of about 1-10 mg/L, a concentration of 80 mg/L is considered lethal.

Lasīju, lasīju (dzerot rīta kafiju), palika dīvaini. Lieliski atceros šīgada pavasari, kad vienā naktī piebeidzu vareno kursa projektu. Uzsildīju daudzas krūzes ar ūdeni un izdzēru ļoti daudzas krūzes ar kafiju. Acis bija platas kā spoles un produktivitāte, par spīti visam, bija apbrīnojama, bet, septiņos no rīta, ja izdzertu vēlvienu krūzi, izvemtu visu ārā. Riebīgi atcerēties.
