Caffeine is the world’s most popular drug. It is produced in a number of ways across the world, notably coffee and tea. Coffee especially is a massive global market, and is grown in South America and Africa. Tea is mostly grown in India and China. Recently the fair trade movement have criticised the way the tea and coffee markets works, claiming that many workers are paid an unfair amount.
Caffeine is legal in all countries across the world.
Some painkillers contain small amounts of caffeine. Some people also self-medicate for ADHD and lethargy using caffeine.
Most people who consume caffeine do not think of it as a drug as it has been traditionally used for hundreds of years in the form of tea and coffee. Nevertheless, it is the stimulant properties of caffeine that have made it popular, as well as the taste of tea and coffee. It can create a mild feeling of wellbeing, or can be used to increase focus.
Caffeine can be addictive, and can be damaging to normal sleep cycles. Caffeine is a diuretic, and causes dehydration. Heavy long term caffeine use can cause damage to the brain, increase blood pressure, and cause anxiety.
