Caffeinated products are some of the most popular, accessible, and affordable psychoactive drugs available in the world. You’ve most probably experienced this drug in coffee, tea, and other energy drinks in your local shop. You may even be reading this with your usual coffee or tea!

It’s estimated around 2.25 billion cups of coffee are consumed by caffeine-lovers all around the world, with many of us reaching for our first cup within an hour of waking. Becoming a large part of our diet, we’re never far from somewhere that sells this cup of energy.

Whether your morning work routine actually depends on the stimulant, or you simply relish the taste, texture, and smell – the presence of coffee in our daily lives is everywhere. And not just for consumers.

Coffee is a valuable commodity for traders around the world, and the demand doesn’t seem to be decreasing for some time, at least. Placed just next to oil for its stock value, coffee is a fiercely-fought over commodity in stock markets all over the world.

Before it reaches our cupboards, coffee undergoes a large manufacturing and distribution process that starts typically in the ‘coffee belt’ – an area covering the middle of the Earth. Over 90% of it is grown and exported from these developing countries, where fertile soil and optimum climates work together to provide great tasting beverages.

But it isn’t just in a cup of coffee where you’ll find caffeine. Tea, energy drinks, and foods containing cocoa beans are all caffeinated, albeit with varying concentrations.

Caffeine is one of the most popular psychoactive drugs on the market due to the rapid rate of effect we feel soon after our first sip.

But how does it work?

When you drink a beverage containing caffeine, its contents are absorbed into your bloodstream quickly, and soon end up in your brain. And, as caffeine is a psychoactive stimulant, it rapidly increases activity in your central nervous system.

We feel a ‘kickstart’ due to an increasing heart rate, as well as tighter muscles.

Several variables exist as to how much we feel caffeine: it all depends on how much of it we drink and our present mental state, for example. Many of us will experience alternative effects, too. Whilst the majority of us will feel energetic and more awake, some users will feel restless, nervous, and anxious.

You’ll be surprised to learn all about the amounts of caffeine in your popular beverages. Do you know how much caffeine is actually in your usual Starbucks takeaway, for example?

Perhaps you are looking for that extra edge in the morning, and need some new beverages to get you through those e-mails.
