Not just about. Literally everything is lethal at a high enough concentration.
LD50's are fun!
Alle Dinge sind Gift, und nichts ist ohne Gift; allein die Dosis macht, dass ein Ding kein Gift ist.
All things are poison, and nothing is without poison; the dosage alone makes it so a thing is not a poison.
Paracelsus, 1538
The word for poison in German is Gift?!
The word has been used as a euphemism for "poison" since Old High German, a semantic loan from Late Latin dosis (“dose”), from Ancient Greek δόσις (dósis, “gift; dose of medicine”). The original meaning "gift" has disappeared in contemporary Standard German, but remains in some compounds (see Mitgift). Compare also Dutch gift (“gift”) alongside gif (“poison”).
Well that's dumb.
"gift" means both "poison" and "married" in swedish. languages are fun :)
Some people would not see a difference in those words, so why not use the same and decide on context xD
I'd argue gravitational force isn't lethal. As long as you don't arrive at whatever is pulling you & the gradient of gravity doesn't change across your body length. You could be perfectly fine (for a while) orbiting a black hole at enormous speeds (assuming you don't collide with matter in the accretion disc.
I'd argue against that. For one thing it is impossible to imagine a situation where there is no change in the gravitational gradient across your body over time. Your orbiting a black hole situation is a perfect example of a situation where the gradient alone would tear you apart. The conditions you've specified are tautological. There's no way to maintain a zero gravitational gradient while also simultaneously having extremely high gravitational field. The two are mutually exclusive in any conceivable scenario.
It's like saying a human being in a hypersonic wind stream won't necessarily hurt you, burn you alive and rip you to pieces (not necessarily in that order) as long as there is no turbulence and you have a sufficient boundary layer -- but you're a non-aerodynamic human body in a hypersonic wind stream, so of course there will be turbulence and the boundary layer will not protect you at all, you're going to die, basically instantly.
The first part of the question asks what is safe in small amounts
Weed. A gram will get you high. A woolpack full of it can crush you like a grape if falling from the hay loft.
woolpack
From Middle English wolpak, wullepak, equivalent to wool + pack.
A bag of wool, traditionally weighing 240 pounds.
TIL, Thx
Took a Hazmat class today and the big thing they drilled into our heads was "Everything is toxic at scale." So make anything you want and there is an IDLH concentration.
dying is a pretty big red flag, you ask me.
Okay. Do you think dying is a pretty big red flag?
I guess I did ask for that.
I also guess you like to tell dad jokes.
ionizing radiation, according to some hypothesis, vitamin E, selenium, zinc,
there's no single "red flag" everything is different
It’s been said a lot that light alcohol consumption is actually good for your health, but this is not actually true. It improves some health outcomes but the benefits are outweighed by the risk. There is no safe amount of alcohol consumption.
Hilarious how the alcohol lobby scratched around for years looking for a good news story about alcohol and came back with some weak sauce link between red wine and heart disease. Meanwhile, 50% of reported sexual assaults are linked with alcohol. Probably more like 80%. How is alcohol legal and LSD is a schedule 1 substance? There is no lethal dose and has been discovered as a treatment for resistant depression and PTSD, OCD, etc. Our drug laws are completely wack.
The real elephant in the room is alcohol is much more destructive and just as addictive than measurable controlled doses of opoids, and also equally if not more destructive than stimulants like amphetamines and cocaine. It's basically the worst drug in every metric. If every alcoholic got their drinks replaced with MS Contin and or weed, the strain on the health system would be much less. Not to mention all the other negative externalities related to alcohol intoxication.
I say all this as someone who drinks. I am going to ensure my child is aware of all the negatives at an early age and be open to discussion about substances. People either like or dislike alcohol, and the people who like it have no self control. It's a stupid drug, I wish I was never introduced the way I was.
Don't even get me started on the alcohol companies producing alcoholic mountain Dew, freeze pops and Sunny D... and they have the gall to ban flavored vapes haha.
I have a feeling that alcohol will come to be viewed in a similar way we now look at religion. It's a cultural artefact from an ignorant time. It serves some purpose and there is a basic utility but overall it has a toxic effect. I hear that research is ongoing to find a credible alternative molecule without the deleterious health outcomes.
Western society has a generally incoherent and childish attitude to substances. Some are viewed as evil e.g. heroin but when this drug turns up in a therapeutic setting, it inexplicably becomes medicinal i.e. diacetylmorphine, which is the acceptable face of heroin, used for terminal cancer treatment.
No substance should be viewed as either panacea or disaster. They are tools that we can use when the time and place is appropriate. We ought to educate ourselves and have honest conversations. Prohibition is getting in the way of this effort and it must go. In it's place we install education, healthcare and hygiene for the mind.
Happy to find a fellow psychonaut. What's your next project in this area? I am considering a psychedelic voyage to the Netherlands.
Everything. Literally everything can be fatal in large enough quantities. Quote from one of my chemistry professors: "there are no lethal substances, only lethal doses"
Remember the Wii craze in 2007? There was a radio competition called Hold Your Wee for a Wii in which the contestants had to drink throughout the day without going for a piss. One died.
"The dose makes the poison" -some old dude that like found the pharmaceutical industry
Water. You need it to live, but you can also drown in it or even drink too much and dilute your blood and die.
According to people I know, I’m only ok in small doses.
Then they leave.
There are lots of things that our body needs in really small doses. But anything above can be lethal.
Some things needs to be in really specific compounds. Like chrome we need really small dose of Cr3+ but Cr6+ is carcinogenic.
My medication. Lithium in small exactly precise doses according to each individual is helpful. But we have to take blood tests to check the toxicity.
We have to stay hydrated and be really careful if we are sick or vomiting
A warning signs is shaking (I tests my hands regularly), nausea and outcome is dying. Ha.
Acetaminophen/Paracetamol. The safe therapeutic dose is very close to the toxic dose. While most people don't intentionally overdose, at least not for treating illness symptoms, the problem arises when they take multiple medications that all contain acetaminophen, following the label for all of them can easily net you a toxic dose.

Cocaine. A red flag being your heart beating itself to death inside your chest.
The human body is pretty weak so anything in high concentrations can probably kill us. It's no steel
Caffeine.
Heartbeats. 60 - 70 is good (you can get away with lower if you're fit, but anything below 40 is bad), and anything above 180 - 200+ tends to be quite bad for your health.
Nicotine, small doses can be okay, but large doses and it's really lethal
Many plant-based drugs, including nicotine, originated as natural insecticides: the plant uses them to make itself poisonous to insects that would eat it.
