A large amount of caffeine consumed quickly can cause poisoning. Because caffeine levels in coffee vary, risk depends on how much is consumed, other caffeine sources, and individual sensitivity. Symptoms can include tremors, nausea, and palpitations, and severe cases can involve seizures; ordinary coffee should not be equated with pure concentrated caffeine.
