1
- 20th of October, 1909, Eastridge, Tennessee, right at the border to Georgia.

4
When it crosses the border, they stop the suspicious truck Without hesitation, they confiscate the entire load.
5
60 barrels of Coca -Cola syrup the contents were adulterated with an addictive and harmful substance: caffeine.
6

7
Starbucks, Monster, Mountain Dew, and Pills.
8
At least 80 % of the world's population regularly consumes caffeine.
9
You probably have some in your blood right now.
10
Maybe you can't fall asleep and that's why you're watching this video.
11
Monster energy!
12
Put it in your body and ask questions later.
13
One scientist calls our caffeine consumption one of the longest, largest unsupervised drug studies ever conducted on the human race.
14
Although caffeine is one of the most studied substances in the world, there are always new findings.
15
However, some companies realized very early on how much power this white powder entails.
16
and they have repeatedly played down its effects.
17
Caffeine is a global billion dollar business.
18
How has a drug that is taken for granted today managed to conquer the whole world?
19
And what dangers does it bring?
20
The world's most widely used mood -altering drug.
21
Is the coffee alright?
22
Uh -uh.
23
Nothing like a Coke.

36
Caffeine is weird.
37
Plants use caffeine to protect themselves from predators.
38
It is found in coffee beans, cacao beans, and tea leaves.
39
In its pure form it is a white powder, tastes bitter, and a bit soapy.
40
A sixteenth of a teaspoon will properly wake you up in the morning.
41
A quarter of a teaspoon will make your heart race, cause sweating, and anxiety.
42
a tablespoon would kill you.
43
However, moderate coffee consumption can even be healthy.
44
It lowers the risk of cancer, cardiovascular diseases, diabetes, Parkinson's disease, dementia, and likely even depression.
45
People love caffeine and have consumed it for several centuries.
46
Europe in the Middle Ages.
47
Monsters are still monsters.
48
We have a hearty beer soup for breakfast, a glass of beer for lunch, and of course beer for dinner.
49
Everyone drinks beer.
50
Always.
51
Not necessarily because of the alcohol, it contained little anyways, but because it tastes better than water.
52
The average British drinks 3 liters a day, including children.
53
In the 16th century a hot black drink from the Middle East amazes Europeans.
54
It looks different than beer, it tastes different than beer, and it has a different effect than beer.
55
Coffee drinkers are soon seen as productive and bourgeois, whereas beer drinkers are considered lazy and comfortable.
56
In 1700, there were already 3 ,000 coffee houses in London.
57
Trade, literature, science, and philosophy flourished there.
58
Some historians even claim that the Age of Enlightenment and industrialization would not have been possible without coffee.
59
Meanwhile, coffee is an extremely controversial topic at the time.
60
Charles II, believes that his people could plan his coup while hooked on coffee.
61
He therefore bans all coffee houses.
62
The public outcry is so great that he revokes the ban just a few days later.
63
Frederick the Great bans coffee roasters, to combat the flourishing black market, the Prussian king hires 400 so -called "coffee sniffers" to track down illegal coffee roasters.
64
The ban is lifted immediately after his death, No caffeine ban in history was successful in the long run.
65
The world's largest beverage manufacturer of today also made sure of this.
66
Coca -Cola was invented by a pharmacist called John Pemberton.
67
It was initially advertised as a medicine.
68
It's said to cure headaches, hysteria, and melancholy.
69
But above all, Coca -Cola does one thing: It wakes you up because it contains cocaine and caffeine.
70
Coca -Cola soon has to remove the cocaine, but it still contains caffeine, plenty of it.
71
At the beginning of the 20th century, the drink has as much caffeine as today's energy drinks.
72
Caffeine has been the enemy of one man from the very beginning, Harvey Washington Wiley.
73
He's the head of the Bureau of Chemistry, the predecessor of the powerful Food and Drug Administration.
74
"He cannot believe that children as young as four are drinking cola." In his opinion, the substance is just as addictive as opium.
75
He declares war on Coca -Cola and orders the FBI to confiscate a shipment of the evil drink.
76
A spectacular court case develops that will pave the way for caffeinated drinks forever the entire United States is watching.
77
The soon to be most powerful government in the world against the soon to be largest beverage manufacturer in the world.
78
Coca -Cola.
79
Wiley and his office call more than 20 witnesses, including doctors, scientists, and regular coke drinkers.
80
In their closing statement, They confidently say: Caffeine is a dangerous drug that could be even regarded as poisonous.
81
Coca -Cola quickly commissions the study itself, as there are virtually no caffeine studies on humans at the time, They hire a young psychologist, give him a lot of money,
82
and have him carry out a number of experiments in just a few weeks.
83
The young scientist delivers exonerating results.
84
His conclusion in court: Caffeine is harmless.
85
Even better, caffeine has a physical and mental performance enhancing effect.
86
Jackpot.
87
Coca -Cola wins.
88
Later, however, there is an out -of -court settlement and Coca -Cola reduces its caffeine content.
89
But what remains in the public eye is that Coca -Cola won,
90
and caffeine is a wonder drug with no side effects and so begins a century of unrestrained caffeine consumption.
91
In the USA, black filter coffee and caffeinated soft drinks initially take off.
92
Then, in the 90s, Starbucks overtakes the drip coffee.
93
The recipe for success?
94
A roast that makes the coffee taste less bitter.
95
Sugar, cream, and very large portions with a matching amount of caffeine.
96
And just when people thought there couldn't be any more caffeine and sugar in a drink, energy drinks entered the scene.
97
In 1987, the first Red Bull can is launched on the market.
98
Ten years later, there are countless suppliers who outdo each other with larger cans and even more caffeine.
99
In some cases there are even 700ml cans.
100
Before you realize it, it's 2024 and caffeine is everywhere, an industry worth hundreds of billions.
101
It's been a hundred years since Coca -Cola's court case, and in the meantime, it became evident that the wonder drug may have a few side effects after all.
102
First of all, caffeine is not a dangerous evil drug.
103
It does not ruin lives or destroy families.
104
Although there are cases of caffeine poisoning, emergency room visits and even deaths, These are extremely rare.
105
According to experts, adults can safely drink a caffeine equivalent of four cups of coffee or two monster energy drinks every day.
106
As a teenager, about half as much or even just a quarter.
107
That's only considering the caffeine.
108
Monster energy is of course super unhealthy, we wouldn't recommend drinking one monster a day.
109
Some people are particularly sensitive to caffeine.
110
Their heart might start to race or they break out in a sweat after just one cup of coffee.
111
This is genetically determined.
112
Others can still seem to sleep like a baby after a double espresso for dessert.
113
The dosage one can take is individual.
114
But even with harmless amounts of caffeine, There are hidden dangers.
115
In one experiment, scientists gave test subjects a soft drink with a new flavor.
116
One with caffeine, one without.
117
They didn't know which was which.
118
The one with caffeine was the clear favorite.
119
Although the caffeine level in Coca -Cola is so low, it still has a noticeable effect.
120
You know, at a lower level, caffeine just sort of makes you feel good.
121
It gives you a little bit of a boost.
122
And even this small boost makes us choose the caffeinated soft drink more frequently.
123
You might not even notice that subtle boost, but you will be more likely to pick up
124
that product again than say an uncaffeinated product that didn't make you feel good.
125
This is Murray Carpenter, journalist and author of the book "Caffeinated".
126
Our body likes caffeine so much that it unconsciously favors almost anything with added caffeine.
127
In one experiment, Participants even loved caffeinated yogurt over decaf yogurt.
128
Caffeine can definitely be physically addictive, according to Dr. Roland Griffiths one of the leading researchers in the field.
129
The drug that more people in the world are dependent on is caffeine.
130
But it's the world's most widely used mood -altering drug,
131
and it turns out that it does produce physical and psychological dependence.
132
According to Griffiths, the mild addiction develops even with small daily doses, a small cup of coffee every day.
133
This little addiction pays off for the industry.
134
Eight of the ten most popular soft drinks in the US have added caffeine.
135
Caffeine unconsciously leads people to consume more sugar, and sugar is quite unhealthy.
136
Coca -Cola claims that they need caffeine for the flavor of their coke.
137
In fact, bitter substances can round off the flavor.
138
But you could also use many other bitter substances for this.
139
Perhaps one that is not addictive, even in small quantities.
140
Scientific blind tastings have also shown that the vast majority of people cannot taste caffeine and Coca -Cola.
141
Nonetheless, the beverage conglomerate sticks to the taste argument.
142
I think when Coca -Cola has said that, I would have to say it's disingenuous because Coca -Cola scientists know full well,
143
everything that we know about caffeine.
144
Energy drinks have just as much sugar as coke, but roughly three times as much caffeine.
145
For most adults, this is not a problem if they don't overdo it.
146
In Europe however, two out of three teenagers and even one in five children consume energy drinks.
147
In the US, one in three teenagers consumes energy drinks.
148
Minors tolerate caffeine much worse than adults and are much more sensitive.
149
Studies show that too much energy drink can have harmful side effects for young people.
150
Then there were adverse effects of young, healthy, young, young, young people.
151
Like Herzrasen, anxiety, nervousness.
152
and also changes in the EKG.
153
There is evidence that long -term energy during consumption can lead to cardiovascular problems among children and adolescents.
154
Unfortunately, however, there are still no conclusive studies on this.
155
Consumer advocates and pediatrician associations are demanding stricter rules.
156
such as a complete ban on advertising energy drinks to teenagers and children.
157
These dangers of caffeinated drinks have not been taken seriously for a long time.
158
thanks in part to the multi -million dollar lobbying efforts of soft drink and energy drink companies.
159
One of the most important lobby groups is the American Beverage Association, which was founded in 1919.
160
Behind it are Coca -Cola, Pepsi, Dr. Pepper and many others.
161
They fund scientists who confirm their views on caffeine and sugar, For example, the group argues against stricter regulation of energy drinks for children and teenagers.
162
Lobbying, a slight addiction, and above all, the awakening performance enhancing effect.
163
All of this contributed to the massive success of caffeine.
164
Why should we question a miracle drug that allows us to become more productive within a few minutes?
165
Caffeine is perfect for the hyper -fast, performance -oriented times we live in.
166
But it's also a time in which it's become increasingly difficult for many people to calm down and relax.
167
It's easy to forget, but physical and mental rest and recovery are extremely important for our well -being.
168
And caffeine actively opposes it, to some extent.
169
Caffeine blocks the absorption of the neurotransmitter adenosine.
170
Adenosine tells us that we are tired.
171
On caffeine, we do not receive this message.
172
The body wants to rest, but we feel awake.
173
For quite some time, actually.
174
About 5 hours after a cup of coffee, half of the caffeine we consumed is still in our body.
175
After 12 hours, a quarter of the dose is still in our system.
176
latte at 2 p .m., you'll still have an equivalent of half a can of Red Bull in your system at 2 a .m.
177
Caffeine makes you fall asleep later and wakes you up earlier.
178
it also destroys your deep sleep, the sleep phase that is most important for recovery and restoration for the next day.
179
We wake up tired in the morning even though we have slept for a solid 7 -8 hours.
180
And what helps against tiredness in the morning?
181
"Ah shit, here we go again." Coffee is often the solution to the problem it has created.
182
People drink coffee in the morning to compensate for their coffee -induced sleep deficit.
183
"You can get into a sort of vicious cycle with caffeine for sure." Temporary coffee withdrawal is easy for most people.
184
But there are still withdrawal symptoms.
185
These include headaches, tiredness, mood swings, and concentration difficulties.
186
They can occur after just 12 hours and last for 5 -7 days.
187
A few years ago, caffeine withdrawal was included as a mental disorder, and the diagnostic management of caffeine was included in the hospital of American Psychiatrists.
188
Several studies suggest that people with a high caffeine consumption are more prone to long -term fatigue.
189
For the same wakening effect, they need to consume more and more caffeine.
190
Experts recommend: Eliminating caffeine, say six or seven hours before bedtime seems to be a very good habit.
191
Caffeine transformed a society of heavy drinkers into a society of wakeful, clear -thinking, productive coffee drinkers.
192
Large international corporations use the addictive effect to make liquid sugar even more attractive.
193
They disguise, play down, and lobby.
194
They also accept the risk of potentially damaging the health of children and young people.
195
Today, caffeine is the drug of our time, without any excessive side effects.
196
But the subtle undertone of caffeine is always: you don't need to rest when you're tired, just have a coffee.
197
But it's more important than ever to listen to the signs
198
of fatigue of your own body from time to time and relax.
