No matter how on top of your game it makes you feel, caffeine does not reduce your level of intoxication. Feeling sober when youâre drunk is dangerous. You may, for instance, mistakenly think that youâre in good enough shape to drive. Your heart is another reason to think twice about mixing caffeine and alcohol.
Experiments with coffee plants offer some clues as to why evolution would reinvent caffeine so often. When coffee leaves die and fall to the ground, they contaminate the soil with caffeine, which makes it difficult for other plants to germinate. Coffee may thus use caffeine to kill off the competition. Coffee plants also use caffeine to ward off insects that would otherwise feast on their leaves and beans. At high doses, caffeine can be toxic to insects. As a result, insects have evolved taste receptors that help them avoid ingesting caffeine.
