- First it tells you what caffeine is. This will be vital for the poster, as while many people may know of caffeine, they might not know exactly what it is.
- Second is to set the scene by giving caffeine a location.
- Third is a more in depth, quirky/interesting fact.
Caffeine has been called the most popular drug in the world. It is found naturally in over 60 plants including the coffee bean, tea leaf, kola nut and cacao pod. All over the world people consume caffeine on a daily basis in coffee, tea, cocoa, chocolate, some soft drinks, and some drugs.
Because caffeine is a stimulant, most people use it after waking up in the morning or to remain alert during the day. While it is important to note that caffeine cannot replace sleep, it can temporarily make us feel more alert by blocking sleep-inducing chemicals in the brain and increasing adrenaline production.
Caffeine enters the bloodstream through the stomach and small intestine and can have a stimulating effect as soon as 15 minutes after it is consumed. Once in the body, caffeine will persist for several hours: it takes about 6 hours for one half of the caffeine to be eliminated.

Caffeine is a natural substance that can be extracted from plants. Natural sources of caffeine include coffee beans, tea leaves and cocoa beans. It also can be produced synthetically.
Caffeine is a type of drug that promotes alertness. These drugs are called “stimulants.” Caffeine acts as an “adenosine receptor antagonist.” Adenosine is a substance in your body that promotes sleepiness. Caffeine blocks the adenosine receptor to keep you from feeling sleepy.
Caffeine begins to affect your body very quickly. It reaches a peak level in your blood within 30 to 60 minutes. It has a half-life of 3 to 5 hours. The half-life is the time it takes for your body to eliminate half of the drug. The remaining caffeine can stay in your body for a long time. Effects can last from 8 to 14 hours.
Coffee accounts for 54% of the caffeine consumption in the world. Tea accounts for another 43%. On any given day, about 85% of Americans use caffeine products. The average daily consumption of caffeine by adults in the U.S. is about 300 mg per person. This is about three times higher than the world average. But it is still only half of the caffeine consumption in heavy tea-drinking countries such as England and Sweden.
Caffeine is a product that has both positive and negative effects. These effects depend on the amount of caffeine you consume and when you consume it:
Caffeine can have a disruptive effect on your sleep. The most obvious effect of the stimulant is that it can make it hard for you to fall asleep. One study also found that caffeine can delay the timing of your body clock. These effects will reduce your total sleep time. Caffeine also can reduce the amount of deep sleep that you enjoy.
The effects of caffeine can occur even when you consume it earlier in the afternoon or evening. One study found that consuming caffeine 6 hours before bedtime reduced total sleep time by 1 hour.
