Koffein forgiftning er meget ubehageligt! 3,2 gram er helt sikkert i overkanten. Koffein har ikke lammepotentiale.

Side effects of caffeine
The minimum lethal dose of caffeine ever reported is 3,200 mg, administered intravenously. The LD50 of caffeine is estimated between 13 and 19 grams for oral administration for an average adult. The LD50 of caffeine is dependent on weight and individual sensitivity and estimated to be about 150 to 200 mg per kg of body mass, roughly 140 to 180 cups of coffee for an average adult taken within a limited timeframe that is dependent on half-life. The half-life, or time it takes for the amount of caffeine in the blood to decrease by 50%, ranges from 3.5 to 10 hours. In adults the half-life is generally around 5 hours. However, contraceptive pills increase this to around 12 hours, and, for women over 3 months pregnant, it varies from 10 to 18 hours. In infants and young children, the half-life may be longer than in adults. With common coffee and a very rare half-life of 100 hours, it would require 3 cups of coffee every hour for 100 hours just to reach LD50. Though achieving lethal dose with coffee would be exceptionally difficult, there have been many reported deaths from intentional overdosing on caffeine pills.
