Caffeine is the most popular drug in the world, i personally have been drinking coffee almost every single day since i first starting drinking it back in 2014, jr. year of highschool. Caffeine is a psychoactive drug and alters you're brain in many ways, like anything, too much is bad. Consuming too much caffeine can result in many negative effects such as, "Decrease your body’s ability to absorb certain nutrients, especially iron, Cause sleep problems – one strong cup of coffee within an hour before you go to bed may cause you to take longer to fall asleep and can shorten the length of your sleep.
