Luyện nói tiếng Anh bằng Shadowing qua video: Why Does Fentanyl Feel So Good?

Fentanyl must be amazing.

Loads of people give up on everything that makes life good for it.

Their loved ones, any other possessions or pursuits, homes, their dignity, and even their lives.

But actually, fentanyl is garbage heroin, inferior in every single way but one.

It's the perfect drug for dealers.

And while we hear a lot about how deadly fentanyl is, many people it kills are not even fentanyl addicts.

It's truly the dumbest drug to ruin your life for.

Let's learn what fentanyl does to you, what it feels like, and why it's so much lamer than heroin.

Pain and pleasure.

Maybe the two most important forces that guide our survival are pain and pleasure.

Pain may be the most visceral physical experience.

A claw ripping your flesh, a bone cracking, eating your soul.

Pain can be scary and unbearable.

It's the strongest signal our bodies have to make us avoid harm.

high fat, having sex, or opening another booster pack with your friends.

Anything that makes you feel pleasure makes you want to do it again.

These two opposing forces guide you through life.

Pain shouts "Stop, this is bad !" "Pleasure, cheers !" "More, do that again !" But while they are opposites, they're also linked.

Sometimes our body needs to end pain and create pleasure at the same time.

After giving birth, pain gets toned down and the with a newborn child.

During an intense hunt, the hunter forgets the physical exhaustion and minor injuries.

Both are technically not great experiences, but need to be repeated for our survival.

And Nietzsche invented a powerful mechanism to achieve this.

The mighty opioid receptor.

It's like a keyhole on the neurons that control pain and pleasure.

If activated, it reduces pain and how much you care about pain, and it creates pleasure and good feelings.

The details are complex and not relevant for this story.

What you need to know is that any molecule

that can fit into an opioid receptor like a key is called an opioid.

Opioids are extremely powerful, so when your body uses natural opioids like endorphins when you laugh, it releases only a tiny amount exactly where they're needed.

So the effects are mild and localized.

Your sprained ankle feels better, a painful memory subsides, you get a boost of happiness meeting an old friend.

And now we're getting to drugs.

and to relieve patients that are in immense pain.

Codeine, OxyContin, Vicodin, and of course, heroin and the worst of all, fentanyl.

Before we can explain why fentanyl is the most garbage drug, we need to do something fun.

Let's inject some heroin together.

Ready?

The Supernova of Pleasure.

Heroin rushes through your entire body and flips every opioid receptor it finds.

A rapid cascade of things happens everywhere all at once.

A symphony of intense sensations.

Every cell regulating pleasure is now high.

Without their control, floodgates of happy hormones open and fill you up top to bottom with pure bliss.

A cup of coffee, a nectar of joy.

symphony, a cuddle, pure love from the center of the universe.

Wherever you felt pain before, from wounds or aching joints or menstrual cramps or loneliness or self -loathing, it's gone now.

You are simply unable to feel pain or care about it anymore.

Like dimming the lights in a cozy room, your brain's alert system is put to sleep and you feel at ease, warm and serene.

Any stress melts You are no longer worried or tense about anything.

This peace even spreads to your essential organs, slowing your breath, soothing and slowing your intestines.

Your chest rises and falls like the gentle waves of a quiet shore.

You are sailing a sea of calm and happiness that feels perfect and eternal.

The full load of a strong opioid like heroin for the

very first time is one of the most amazing feelings humans can experience.

For a few hours, you're in heaven.

And this is exactly the problem.

Your brain is not equipped to handle anything like it.

You feel too good.

But nothing lasts forever, And now you're in trouble.

You just experienced the best feeling you ever felt.

Your brain's reward center is completely fried and can't comprehend what happened.

If what you did felt this good, it has to be amazing for your survival and you should do it again.

Except, you can never ever feel this good again.

This will be your peak life moment forever.

You may forever chase this feeling you had this very first time, and now you're back in the regular world.

with your insecurities, where your knee hurts, regular tasting coffee and having to work hard for happy hormones.

Comparison is the thief of joy, and now you have your life to compare to a supernova of bliss.

The indescribable feeling comes with a damage to your sense of life and self that may be irreparable.

And this is not even the worst.

Opioids are incredibly addictive.

and the addiction among the worst you can have.

The supernova of pain.

Once you've taken opioids a few times, your brain has had enough.

The cells controlling pain and pleasure are constantly high and drowsy.

so it boosts them and makes them hyperactive.

This happens very fast, sometimes after a few days of use.

you've developed an opioid tolerance, toning down all the nice effects you're doing the drugs to achieve.

To feel like before, you'll need way higher doses.

Now you're at a crossroads Quit and have your system go back to normal fairly quickly, or keep going and take more.

You take the wrong turn.

Over the next few weeks your brain keeps pushing back and you keep taking more.

The effects are not quite what they were, but still mildly nice.

Until one day you can't get opioids and realize your body is now your enemy.

Your systems are so hyperactive that they make you feel the opposite of what the drug was doing.

Welcome to withdrawal.

It all starts with a creeping unease.

tasteless, your favorite song lame, your loved ones distant.

A storm of negative emotions shatters your sea of calm.

Serenity is replaced by anxiety and angst, like something terrible is imminent.

Your worries, insecurities and all the fears you suppressed aren't just back but amplified into an existential crisis.

You're so restless you can't sit still.

Your heart hyperventilate.

Your pain circuits are now over sensitive so your bones and muscles ache and hurt for no reason.

Old wounds, physical and mental, torture you.

You have belly cramps and diarrhea and have to vomit.

You're too agitated to rest.

A war inside your body that you can't escape.

And of course, there's the craving, screaming for you to make it stop.

100

Your mind and body beg for a hit.

101

You can be in this state for up to two weeks or make it stop right away.

102

Okay, so why not just take heroin forever and feel amazing always?

103

effects like euphoria faster than to the bad ones like dangerously slow breathing.

104

So it turns from touching the love center of the universe to mostly drowsy numbness and relief from withdrawal.

105

Now you don't take opiates to get to heaven, but to avoid hell.

106

You're in a prison of your mind and body, unable to connect with all the things that could actually make you feel good.

107

Opioid addiction is brutal and extremely hard to escape.

108

It should be pretty clear that you need to be extremely careful with any opioids, and if you have the chance to do it for fun, just don't.

109

There's a very real risk that your life might just be over, and that you'll go through hell.

110

Now that we've seen the heaven and hell of heroin, we can get to fentanyl, the garbage drug.

111

Fentanyl is really garbage heroin.

112

Everything we just described is true in different intensities for most opioids.

113

They can be great, all of them can be hell.

114

Heroin is just sort of the strongest, except it isn't.

115

Fentanyl is around 50 times more potent than heroin, but that doesn't mean 50 times more amazing, quite the opposite.

116

Fentanyl is extremely good at crossing the blood -brain barrier, the firewall that protects your brain from harmful substances.

117

It enters your brain so easily that you get from zero to extremely high almost instantly.

118

But just as fast as it enters, it leaves again.

119

hours.

120

One from fentanyl can fade in minutes.

121

Fentanyl doesn't feel as good as heroin.

122

Instead of a supernova of bliss, you mostly get the black hole of nodding away.

123

But it comes with all the withdrawal symptoms.

124

As a bonus, because fentanyl acts so quickly on your brain, it fries your reward center even more, making it even more addictive than heroin.

125

And since you only need so little of it, it's super easy to overdose and die by accident.

126

It's by far.

127

Between 2013 and 2023, it killed about 400 ,000 Americans.

128

Fentanyl really is garbage heroin.

129

Too dangerous, too intense, too addictive, too little fun.

130

But then why are so many people taking it?

131

Well, actually, nobody wants to.

132

Fentanyl is not for users, it's for dealers.

133

The house always wins.

134

Fentanyl is a drug dealer's dream.

135

One truckload could supply the entire US for one year.

136

It's cheap to make and easy to smuggle.

137

Heroin needs plants and fields and way more space.

138

So garbage fentanyl just took over the heroin supply.

139

It might have seemed great for heroin addicts at first, and then its trap snapped closed.

140

While some people may seek out fentanyl specifically, several studies have found that most opioid users try to avoid it.

141

Even worse, a lot of people who die from fentanyl don't take it willingly.

142

Dealers want people to come back for their product, and by adding a tiny trace of fentanyl to any drug, they can make it more addictive.

143

Even if people don't realize they took an opioid, they'll feel its effects.

144

started to mix all kinds of drugs with fentanyl, turning the entire US drug market into a minefield where any trip can be your last.

145

Because way too often, they put a bit too much in their mixes.

146

In 2022, the combination with pills, often counterfeit oxycodone, and benzodiazepines, accounted for about 20 % of all fentanyl deaths.

147

In 2023, the US authorities seized 115 million you About half of fentanyl overdoses came where you expected the least,

148

from stimulants like cocaine and meth.

149

A lot of people may have taken these mixes on purpose, but many others just wanted to party and weren't ready for an opioid surprise.

150

This is especially dangerous because if you've never tried opioids, you can overdose very easily.

151

Fentanyl really has no upsides outside medical use.

152

For dealers and cartels, it means easy profit.

153

For users, it means a worse opioid addiction and a worse life.

154

For people who would never ever try it, it can be a death sentence they didn't see coming.

155

No matter how alluring they are, using opioids even in safe settings is playing with fire on the best of days.

156

Fentanyl is a garbage drug that turns this fire into a raging furnace, increasing the risk of death massively.

157

There's really only one conclusion to draw here.

158

If you have the choice, Don't step into the supernova of pleasure.

159

Because the danger of it turning into a supernova of pain is just too high.

160

Getting to the root of an issue requires looking at all sides and thinking critically about the information we consume.

161

In today's world, this can be difficult.

162

This is why Ground News is such an important tool today.

163

We believe in their mission and are proud to have them sponsor this video.

164

In a nutshell, the app and website combined the world's news in one place so we can do just that.

165

Taylor reporting on a US bill about harder punishments for fentanyl smugglers.

166

Fewer than 75 sources worldwide reported on the story, but the headlines were quite different.

167

Other sources praised the step and said it could end the crisis.

168

And some media outlets asked if the smugglers are really the problem, and if policy makers shouldn't focus on the problem of demand in the US itself.

169

The interesting thing is that no government -funded sources are covering the topic.

170

Reading the news this way lets you compare different sides and the context of a story in one place, so you can analyze the information for yourself.

171

You get a sense of different perspectives and can hold yourself accountable to avoid information bubbles and confirmation bias.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
