Introduction to the History of Drugs
HTML-код
- Опубликовано: 4 сен 2024
- A drug is a substance that, when introduced to the body, produces some non-nutritional physiological effect. This includes medicinal drugs as well as recreational drugs, and they take many forms. Focusing predominately on medicinal drugs, what is the history of our relationship with these substances? How did the ancients attempt to cure disease? How do we do it now? How has this changed over the millennia? This is a fascinating story, that traces human thought from the Stone Age all the way to the modern pharmaceutical industry. Let's learn together, about the history of drugs!

Now do a scientific episode with you trying all the drugs.
For science
You don't "try" drugs, they are prescribed by a physician based on what he has determined is wrong with you.

I’m disappointed that you call the medical field science. What other branch of science has side effects, never gets it right, and always limits it’s answer to pharmaceuticals?
Science doesn’t have ALL the answers, but the medical field has NO answers. And whenever someone figures out an answer, they are ignored by the medical field. Like in the following video. Which is from 2018 and was made years after I began making this kind of video.
Yes, I say science in the video. It’s not science. It’s just sciency. I said science for the same reason doctors call their field science: marketing.
You can’t know (because you can walk), but what happens in this video is the most profoundly life-changing thing that can happen to anyone. And yes, it does involve a pharmaceutical. But it’s just one pharmaceutical, and it happened specifically because I don’t take any of the other pharmaceuticals that are prescribed for everyone with my condition.
The reason why this doesn’t happen to anyone else is because everyone else is prescribed five or 10 pharmaceuticals the moment they’re diagnosed with arachnoiditis, even though the pharmaceuticals don’t make anyone better and cause total fucking hell (side effects”). By the way, I had never heard of arachnoiditis when I made this video (because five years earlier, doctors ignored the science of my MRI results).
Consequently, I suffered immensely for another six years. Science doesn’t do that.
What’s even more ridiculous is the fact that a significant chunk of the medical field has made the general population believe the amazing drug that did this to me is not only bad but really bad.
Having done no research, I’m pretty sure the average lifespan didn’t increase because of pharmaceuticals, and that it did increase because of hygiene.
I’ve done a 180 in this department, because the shit hit my fan. I used to think of the medical field as science, but I guess that’s only because I was healthy enough not to have been destroyed by medicine. Now I’m not.

"how did we get here"
Hello Professor Dave, I would like to thank you for your videos. They are very helpful. Continue to make more videos.
Looking forward to this wonderful series.
I love how you explain things in such a simple, easy-to-understand way, without sounding like you're dumbing anything down for your audience. That said, I was a little disappointed to hear you talk about average life expectancy without explaining that one big reason why it was so low was because of all the infant and child mortality, rather than people who lived to adulthood only living until 40 or so.
Agreed. Infant mortality and death in childbirth dramatically decreased the average life expectancy.
Yes this video is mostly misinformation from misrepresenting what average age meant (not that people lived to 33 but that half of them died before 10 and rest made it to 50), and claiming we can extend life indefinitely, which is pure cuckooland you hear in some wacky cult.
Hey Dave, just wanted to say thank you for all that you've done! Your videos have helped inform and educate people around the world, myself included. Thank you so much for your generous work and for your scholarly zeal! Not all heroes wear capes... But some rock an epic beard ❤️
I'm brazilian and I'm completely in love with your channel! Can't stop watching it! Congrats!
I was expecting a tighter focus from the title, but the breadth of what is to be covered has got me really excited. Thanks Professor!
Thank you for helping me with my research Professor Dave you have made my day. 🙂
I have visited the Pharmacy museum in Basel Switzerland recently, it was very interesting and I start searching in this area. Then I found your videos. It’s exactly what I want to know. Thank you very much indeed to make these kind of high quality videos.
I couldn't be happier to see your name pop up when I search a new topic ever since I found you last week from your GlobeBusters response. You're a new favorite take all of my subs Dr.Sir
Prof Dave this series is a fantastic idea and to start it with those charts on life expectancy is very important. I was showing to some of my family member the effects of science discoveries ( quantum physics and microelectronics) on our lives and life quality trying to give them a sense of respect for real science and those Giants on whose shoulders we have built our modern lifestyle, i will pass to them this video and encourage them to follow the whole series. From Singapore thank you Prof Dave.🙏🏻👍🇸🇬
2nd time around this series is still just as good, if not better. I really hope you do another historical deep dive into some other topic, like trade or warfare. It would be awesome to see a history of sciences too, although you cover a ton of it in this series and that could be too broad of a subject. Still, I’d pay a dollar to see that.
im super stoked for this series. your content looks slicker than ever.
Great introduction! So many nifty cliff-hangers! I'm really looking forward to this series, Professor Dave.

Sorry...DH??
Thanks for starting out with the definition of a drug. Lately been seeing people make distinctions between psychedelics, plant medicines, and drugs... and it’s all drugs y’all
Professor Dave thank you very much. I think a series of videos debunking homeopathy, reiki, acupuncture and magnets would be really informative.
6:35 Remember everyone: "average life span" can be drastically changed just by changing the number of people who die very young.
In the first agricultural civilizations, the number of people living to adulthood & the number of those adults living til old age could have (and likely did) increase, overall much longer than before the agricultural revolution.
However, if more babies were being born at the same time, and child mortality was still very high (definitely the case)...then that drops the "average life span."
Ironically, the very fact that people started living so much longer contributed to this, because the longer you live the more times you can get pregnant & the more babies you have...which means the population of infants & people under age 5 massively increased, and subsequently the total number of people who were born but died before their 5th birthday massively increased.
There were more people dying before their 5th birthday, but there were also more people living past age 5. There were more people living well into middle aged too, long after the average life span...but those improvements in average life span can easily be hidden simply by adding enough people dying very young.
Think about it...if a mom has 3 kids who live to 80 and no deaths, then her personal average & her contribution to the total average will be *better* than a mom who produces 6 adults who live til 80 but also gives birth to enough children who are dead by age 2. Over all, the second mom has added *twice* as many adults who live til 80...but the first mom has a perfect score simply by not having as many children as the second.
In fact, this will be the case even if in reality, the first mom is less healthy & lives shorter, being unable to carry more than 3 pregnancies to term and miscarrying the rest.
While the second mom is healthier and lives longer, subsequently getting pregnant more & having way more babies, despite the exact opposite being reflected in the total averages.
Or, the moms could get pregnant the same number of times...but the first mom miscarries before giving birth, so it doesn't count against her total average. Meanwhile, the second mom manages to give birth to those children, even if they only end up surviving a couple days (potentially ultimately only making it a month or two longer than the ones who died before they were born).
Literally you can get a crazy different average just by changing the outcome of certain unviable pregnancies...the ones where the fetus has a health condition that will make it impossible for the baby to survive longer than a day or 2 after birth...if they survive til childbirth at all.
In one case, the baby is delivered still born...in another case, the baby is actually alive when born but inevitably dies within 24 - 48 hours.
While an extra week of being around should not affect the overall average life span when the person is old enough (as in, even if there's a condition in half of all people who live to 80 that for whatever reason assures they will die one week earlier than they would have without the condition...they've already added so much time to the average life span, that a week won't affect it)...it makes a massive difference when the person dies young enough.
An extra week of time can make the difference between having no effect on the average life span to having a massively detrimental effect on the average life span. It goes from a person not being counted at all, to a person suddenly counting because they technically survived child birth before dying day 2.
Agree!
Simply put,, the low average is due to infant (
. You explain that very well! So easy, even a Caveman could understand it! You really do break it down easy to understand, Sesame Street style, THANKS!
Great idea Dave! This is one of my favorite subjects and I am looking forward to learning more about it. Thank you!
Thanks.
Today the question ' how the drug we use now a days, were applied first?' come to my mind.And i find your playlist.
That opening jingle fckng SLAPS!
Do you ever cite your sources on any of this?
Hi sir my daughter got a lot from your video. Thanks and keep then
Great clear informative video with great pacing and you have a great voice too
Great video! I love all the animations and stuff; very high quality presentation and content. I look forward to the rest of the series; I know I'm going to learn a lot! I do have some notes, though:
"We understand that our ability to pursue this goal is not only scientific in nature, but political, and we presume that the prevailing political conditions--at least in democratic societies--coincide with such a goal. Although this may not always be the case."
-No you were right, it is always the case, categorically. The contradiction isn't that sometimes egalitarian democracies don't care about their own people, it's that the United States, Venezuela, and Brazil are not egalitarian democracies, they are right-wing dictatorships. In much the same way that North Korea calls itself a democratic republic when it clearly isn't, self-descriptions are unreliable.
"That is, we want to enjoy the things, both material and spiritual, which combine to make life a worthwhile experience."
-This is a surprisingly theistic thing to say. Life most certainly does not need belief in the supernatural to be worthwhile.
"A side effect is that the average life expectancy is higher in richer countries than in poorer ones. While this may seem unjust, it is the reality of our current politico-economic framework, and is unlikely to change anytime soon."
-It is unjust. The fact that it is our current reality doesn't make it just. The fact that it's unlikely to change anytime soon doesn't make it just. And it's even less likely to change with that mindset. Call it like it is.
"The additional goal for the pharmaceutical industry is, of course, to make money."
-Weird that you'd call it an 'additional' goal here, when the very next thing on the screen is that it is the *primary* goal of any business to maximize profits, which is objectively correct. The phrasing of 'additional goal' seems to paint the pharmaceutical industry as prioritizing the goal of human health over their secondary goal of profits, but since you immediately contradict that, it sounds like it was somehow unintentional.
"This includes the cost to the patient, and how society is handling the noble ideal of providing state-of-the-art treatment to as many patients as possible, while preserving the rights of the innovator to make a reasonable financial profit."
-Preserving the 'right' of an innovator to be placed or retained in an elevated group (financially and otherwise) is to maintain the very kind of social hierarchy you talked about earlier that leads to the injustice of preferential treatment for the rich, which is incompatible and completely antithetical to a truly egalitarian society that would want to fulfill all of the needs of all its members. For life to get better for everyone (including the innovator), we need to let go of the idea that we need to make a profit, climb the hierarchy, and be treated better than the 'less deserving'. That's what holds us all back.
He didn't say supernatural, he said spiritual, very different things. There's a lot of evidence to support the role that "useful delusions" play in psychological resilience. Many studies are finding the benefits in spiritual communion that fosters a sense of awe and gratitude. It's like we're hard-wired to desire the transcendence of self and the dissolution of ego, to collapse from a particle back into the wave field of earth consciousness.
Why is Andrew here? He didn’t say anything. But he doesn’t really carry himself the same way. He shows his guests respect and kindness and I could watch him all day.
Do you edit all of these videos? I always love the graphics and clean animations :)
I will be glued to my inbox waiting for these videos to show up.
This semester i have pharma so these will be helpful thank you
Thanks for putting the effort into the video. Also your voice is really easy to listen to.
Well one important thing you mention just very short in passing about live expediency is how child mortality plays a mayor role so to say doable live expediency i heard is kinda precise because it is more an effect of less dying children.
Thank you for the knowledge
Makes sense that society, in general, extends a conjecture that substance use disorder seems disease-esque. The rigid, contradictory lexicon - concerning substances in any which way - prescribed to modern society has boggled me for ages
Looks like its going to be an amazing series! Maybe you can follow this up by making just a history of humans series?
Looking forward to this series! Particularly the bioethics portion!
Was it ever continued?
Any thoughts or critiques of Antonio Escohotado's General History of Drugs?
Looking forward to new episodes. Btw when are you going to make videos on physics or mathematics??
I have hundreds of videos on physics and mathematics! More coming soon, but check out what I've got so far.
@@ProfessorDaveExplains Yes I've watched them. I just asked because i want to learn about differential equations and how they apply to modern physics.
Oh yes, I'm planning quantum mechanics content with math, and searching for someone to write differential equations content as we speak, since I can't do it.
I hope this dives into the founding history of some major pharmaceutical companies as well. Merck has a fascinating story

Is there anyway to get a timeline like that?
I've received a lot of negative feedback when trying to put forth the idea of quasi-immortality. Seems like a good method for raising the percentage of 'death with dignity.'

Well done. This is a fascinating topic that I’ve studied for 15 yrs. but I digress
As you probably know, the king of the modern ‘flerfer’ movement has rebutted a video of yours and has spurged a Dunning Krueger masterpiece that could destroy the move...eh, let’s face it..the wheat has already been seperated from the chaff..but it might be fun and get you a lot of views🙂👍
This is a really cool perspective, and well presented.
Isn't it interesting how humans, and humanity as a group, are instinctively compelled to control. This *must* include controlling the use of substances that can negate or change the way people are influenced, or participate with the broader concensus of accepted social behaviors. If there IS anything that truly sets humans apart from other animals, it's the ability to organize in vast groups. It follows to reason that substances that negatively influence this, will be tightly controlled, and ones that positively encourage those behaviors will be promoted. Alcohol advertisement is a fair example of the latter, because despite the damages and tragedies it produces, it also ameliorates many of the common redundancies and tedium of daily participation in an industrialized culture. Hence even the use of the term functional alcoholic.
Damn my teacher sucks at explaining complicated stuff so she just showed this video instead.. i learned way more in this video than her discussion this past couple of weeks
Wonderful.
Cery cool video as always. Penicillin man wow.
Awesome Video. Love your channel
Hi Professor Dave, not sure if you can assist me. I have a 12 year old whom I home-schooled. This morning we watched your video and when the chart of "average life span during Stone Age" showing, she asked me how the chart shows shorter age than what she learns from the Bible. For example, the bible mentioned that Noah and Abraham lived for over hundred years of age. I checked google that Abraham was born in 2150 BCE and lived until 175 years of age -- she has her point. Really appreciate any insight.
Yeah, the bible is a work of fiction. None of those people existed.
@@ProfessorDaveExplains not that they didn’t exist, more likely hyperbole
@@ProfessorDaveExplains Dude, Cyrus and Nebuchadnezzar are literal historical kings, you have to be some insane conspiracy nut to deny none of the people from the Bible existed. You're looking not much better than these American Young Earth Creationist with your idiotic statements.
@@yerpsternah he's one of those lunatics who claims Jesus, Cyrus and Nebuchadnezzar didn't exist because he's in that euphoric cult which is just as silly as YECs who take all metaphors in Bible literally.
Ah, okay I see where the problem is. I came to this playlist after our previous discussion in a video about Quantom Mystics.
What I speculated might actually be right, but I had some deficiencies in my understanding.
I read an intersting BBC article a few minutes ago, and one of its claims is that the modern method of anthropologists is a bit misleading in determining average life expectancy.
As a result, may believe that some people live to an old age, but on average, you will die between the ages of 30 and 40 if you live in those times. This is very misleading indeed, as ancient literature points to almost nothing of this sort. The average is a mathematical calculation which definitely conveys a message, but unfortunately too many people have gotten the wrong message.
The BBC article is called "Do we live longer than our ancestors" and I believe was published in 2016.
Also, in it, it does credit modern medicine with allowing the actual average life expectancy to increase and allowing humans to live till old age, thus completing their life span.
and this all points back to what I have conclluded about "histlry" long ago.
"The accuracy of historical interpretation is dependent on the amount and quality of hostorical information that is preserved."
Once again, thanks for engaging with me in these discussions. I LOVE intellectual discussions. I found that one of the best things you can have for free is a STIMULATING discussion.
Nice! the video graphics look new !
If only there where some way we could get rid of the economical constraints of our society.
Ok mr. Prof. Dave , I have a question that is not necessarily about this video but about the beginning of man, and since as far as I can tell you are somewhat of an expert on an awful lot of things, (and I very much enjoy your videos) can you please tell me how we gathered all the different kinds of foods over the years? How or who was given the job of going around to everything on the earth and tasting it to see if it was edible and tasted good? Like who on earth looked at a stalk of wheat and thought it looked good enough to eat and then ate it and then realized that it would be good to use in making so many other things? How come we don’t eat maple leaves? Did someone at some point in time actually taste one and put it on the no list? How come we don’t normally eat bark off trees? Did someone at some point in time actually go around tasting all the tree barks and thought yuck until they came across the one that tastes like cinnamon? And if so considering you can’t eat cinnamon alone because it doesn’t absorb water which makes our saliva no help at all? AND since I seem to be on a roll here, how or who went around naming everything? Who had the idea or right to decide that a tree should be called a tree, or a human a human, or any animal, plant, the sky or air or anything at all should be called what it is today ??? If you could answer these questions I would be very grateful, as it has puzzled me and many I know for an awfully long time now?
Well I don't know much about this, but I don't think it was any more sophisticated than trial and error. That was it. We just tried everything. Some things aren't eaten because it's not practical. Tree bark is not easy to eat. But then with the agricultural revolution we began manipulating plants and artificially selecting for traits. Pretty much everything in the produce section at the grocery store is of human design actually.
Professor Dave Explains Thank you for answering me 😌
If kids can go around eating things off the ground, you better believe that after 200,000 of hominids, and ~5,000 of advancing civilizations, someone tried the plant, boiled, baked, or bashed, found it had an effect, and made use of it. Cumulative knowledge over time. And like Professor Dave said, once we had agriculture, we started selecting plants for desirable traits, just like we did to get all the dog breeds from wolves.
Nice..🙂👍

Hello may I ask for the script?
Engineering made a far bigger impact.
Clean Water supply, sewage, drainage, housing etc prior to the big advances in medicine and medical treatment.
These advances certainly contributed. But far bigger impact? How do you quantify this? It is hard to dissect a host of advances which were going on at the same time.
@@galileog8945
"How do you qualify this"
You could start with the old adage of, prevention is better than cure.
@@davidwatson2399 Adage? Come on, be serious. I asked "how do you quantify this?" not "qualify". We just do not know. You are guessing.
@@galileog8945
No I'm not guessing, I have alredy given you a line of research to investigate.
Water: Dams, pipelines, viaducts, tunnels, filtration, treatment, distribution, storage, plumbing, = engineering not medicine.
Sewage: Plumbing, pipelines, treatment, disposal and separation from clean water resources = engineering.
Food: Transport, storage, preservation, distribution etc, = engineering.
Disease vector control, mosquitoes, flies, ticks, fleas, etc = mechanical and chemical engineering.
Bio medical equipment, monitors, ECG, pathology lab equipment, radiological equipment, CT, MRI etc = engineering
Even vaccines and medicines are relient on engineering, for production, packaging, transport, storage, etc.
So no I am not guessing, use your computing device to investigate the importance of engineering on human health and disease control.
@@davidwatson2399 OK, now you are being ridiculous. What are you, a frustrated, unappreciated engineer? The series is about drugs extending average human life span. This is beyond any doubt, but perhaps the fact that the series celebrates biologists, chemists, medical scientists, not engineers seems to irk you. Better sanitation, clean water and clean hospitals have certainly contributed to reduce mortality. But why more than drugs? The smallpox vaccine is estimated to have saved 250 million lives. Indeed, engineers contributed to this effort as well, but it was a medical advance, and engineering alone could have done nothing to help against smallpox, unless you count isolation as an engineering tool. And bacteriologically clean techniques were introduced only when some microbiologists convinced everyone that bacteria exist and can be highly pathogenic. Only an engineer (a rather deluded one) would count medical diagnostic devices among the best engineering contributions. Take magnetic resonance: who developed the theory and created the knowledge for the machines we use today? Physicists, who told the engineers what they needed. Indeed, the physicists got the Nobel prizes, not the engineers. Paleontologists argue that human life span dropped considerably (by 5 years) when people settled into stable communities, i.e., when the first primitive engineers organized towns and villages. Why? Although the quality of life improved in many ways, growing tightly-knit communities were fertile grounds for person-to-person transmission of infectious diseases, and better infrastructure did nothing to stop it.

I sure have a horrible history of drugs, and I don't mean in a good way. I abused common street drugs for quite a long time, and right from the start it was injecting opiods, starting with Oxy Contin back in the early 00's, to heroin just a few years later and up until 2016 when lnding myself on Drug-Court helped me break free from that miserable addiction and lifestyle. I of course abused many other controlled substances throughout the years as well, but for sure I observed opiods causing more harm to myself and others than any other controlled substance I know of. Life has been so much easier to handle for these past 4 years of sobriety, and no risk of dying from an opiod overdose.

I was arguing with a flat earther on a conspiracy discord and they asked this.
"How can a Railgun shoot 100 miles? Thats 6,666 ft of missing curvature", or something on the lines of that
i wasnt able to answer at the time but my conclusion is that it travels faster than the curve of the earth so as the earth curves it decends at the same time. Im not sure this if this is true or not because im not as educated as you. could you please give a sciency explanation to slap a flat earther with when they bring this up?
They fail to realize that the rail gun does NOT shoot in a straight line. For short distances, (a couple of miles) yes, like in their test videos, but at 10 miles or more, you need a trajectory or parabola to hit a target that far away. Flat earthers conveniently ignore that fact. ruclips.net/video/OJV18qzA7Fo/видео.html
