  • Life on earth can be a dangerous one

  • Some things are poisonous, other things have sharp teeth, and more things can kill you without

  • you even noticing.

  • In theory, anything could kill you.

  • Really, it just depends on how much or how little of it gets inside of you.

  • In this video, I'll be comparing the most dangerous materials and substances known to mankind with

  • a lethal dose being administered to an average human weighing 62 kilograms.

  • If you weigh less than that, these doses will all be smaller for you, and if you weigh more, then

  • the doses will be greater.

  • So considering the weight of the average human, we're going to start off with regular water.

  • In order to die from a lethal dose of water, you would need to drink 5.6 kilograms or one and a half

  • gallons in a rapid amount of time.

  • Other common household items you need to consume a ridiculous amount of to die from include

  • table sugar, which you would need to slam down 1.8 kilos worth of to die from.

  • But if you're feeling salty, you need to consume a whole kilogram of MSG to die that way.

  • Death by Vitamin C requires you consuming 738 grams, and death by alcohol means you need to consume

  • 438 grams of pure ethanol, which is roughly 25 shots worth of 80 proof vodka.

  • If you prefer smoking, then you should know that it takes 79 grams of pure THC to create a lethal response

  • inside of the body.

  • Since cannabis leaves only have a small amount of THC inside of them you would need to smoke an

  • outrageous amount of weed to die from an overdose,

  • approximately 680 kilograms, or half the weight of a Toyota Corolla, in 15 minutes.

  • Drugs like Ibuprofen can be lethal at around 40 grams, which is about the same weight as an adult mouse,

  • while chemicals like hydrochloric acid approach lethal levels at about 15 grams.

  • In a concentrated, pure form, caffeine can kill you in as little as 12 grams.

  • But that shouldn't make you worry about drinking caffeinated drinks because you would need to

  • consume 116 cans of Red Bull, or 60 cups of Americano coffee to induce a lethal reaction that way.

  • Drugs like MDMA, or Ecstacy, aren't much worse with a lethal dose being around 11 grams worth.

  • Eating a block of Uranium about the same size as a €1 coin would probably be enough to kill, while consuming

  • a US quarter-weight worth of cocaine would also do the trick.

  • Thiopental Sodium, the ingredient used in most lethal injections, can induce a fatal reaction in as little as

  • 4 grams.

  • While methamphetamine can do the same in just 3 and a half grams.

  • But Mercury is even worse, an extremely toxic metal used in applications like thermometers that can

  • kill you with as little as a US penny-sized amount.

  • But after this point is where we arrive at the most lethal hard recreational drugs,

  • Heroin and LSD, both of which can kill you in as little as one gram, or about the same weight as two raisins.

  • In its pure form, Nicotene can also be lethal in doses as small as 403 milligrams.

  • But since tobacco leaves have so little, your only risk of dying from smoking cigarettes is the long-term

  • health effects associated with them, like cancer.

  • The most venomous scorpion in the world is the appropriately named Deathstalker Scorpion, and its

  • venom can kill you in a dosage as small as 267 milligrams, which is only slightly less dangerous than

  • Hydrogen Cyanide, which can kill you in as little as 229 milligrams, or about the same as a one-carat diamond.

  • But nothing that we've covered so far is as dangerous as what's about to come next.

  • Pufferfish are infamously poisonous and can be fatal to eat since they contain the toxin called tetrodotoxin,

  • and ingesting an amount as small as only 21 milligrams could be enough to kill you.

  • This is almost as toxic as Plutonium, which if it's not being used in a nuclear bomb to kill you, a small

  • sample size of 20 milligrams would also leave you just as dead.

  • If eating mushrooms freaks you out, there's a pretty good reason for that because eating just half

  • of a so-called death cap mushroom would be very, very fatal.

  • This is because they contain amatoxin, 19 milligrams of which will kill you if ingested.

  • But there's still a lot worse to come.

  • Sarin, an odorless and colorless liquid, is so dangerous that it's classified as a weapon of mass destruction

  • under international law.

  • Often used in chemical weapons, a lethal dose amounts to just 11 milligrams, or about the size of a grain of

  • sand.

  • Inhaling a lethal amount can kill you in just 1 to 10 minutes.

  • And even in you survive, permanent nerve damage is almost a guarantee.

  • But weirdly, there's still creatures out there that produce more potent poison than a weapon of

  • mass destruction.

  • Like the Brazilian Wandering Spider, whose venom can kill you in amounts as small as 8 milligrams.

  • Or the Inland Taipan Snake, found in Australia, whose venom can kill you in a dose as small as 2 milligrams,

  • or the weight of a mosquito.

  • The extremely powerful toxin Ricin, produced in the seeds of the castor oil plant, can kill you if you inhale

  • even one milligram, which has made it popular for assassination attempts and biological warfare

  • around the world.

  • But latrotoxin, the venom produced by the Black Widow spider, will kill you even quicker in amounts as small as

  • just 267 micrograms.

  • The strongest poison any known creature makes on its own is batrachotoxin, found in the so-called

  • Poison Dart Frog.

  • 124 micrograms is all it takes to kill you, about the same weight as two human eyelashes.

  • But there are at least two substances that are even worse.

  • One is called Polonium-210, so dangerous that that if you inhale just 620 nanograms, about the same as

  • two to three grains of pollen, you would die an agonizing death.

  • it is 250,000 times more toxic than hydrogen cyanide, and was used to assassinate Russian dissident

  • Alexander Litvinenko back in 2006.

  • But by far, the most lethal toxin known to mankind is Botulinum toxin, which is commercially sold

  • as Botox.

  • 62 nanograms is all it takes to make you dead, about the same weight as 62 of your body's cells.

  • It's 2.5 million times more toxic than hydrogen cyanide, but only very tiny fractions of that lethal dose

  • are used in commercial Botox.

  • Doctors and medical professionals that administer Botox have websites than can explain much more about

  • this than I can in a short video.

  • But if you're looking to create your own website to help explain what kind of business you do, there's no

  • better place to go to next than SquareSpace.
