Cool science post!!! Please enjoy! And keep in mind just because something has a higher LD50 (more needed to kill you, less toxic) doesnt mean it's magically Better. Aspirin has a lower LD50 than hydrochloric acid, vitamin D has a lower LD50 than cocaine, and nicotine has a lower LD50 than heroin. Also, this chart doesn't take into account chronic health effects or sub-lethal toxicity. Just how much is needed to kill you in one dose.
A few things that stood out to me (assuming a statistically average, 70kg adult):
>MSG is 5 times less toxic than table salt, per gram (it has 5 times less sodium per gram). And it tastes better, too! The long term health effects (other than specific allergies, which are immediate) are minimal, its a misconception that it's extremely unhealthy.
>Botox will kill at 0.000000002 grams. And we inject it into our faces to look younger. What the heck, guys.
>LSD is dosed in increments of 100μg, or at about 11,000x BELOW its acute toxic dose. This is known as a "therapeutic window", how far is the useful dose from the toxic dose. LSD has a fantastic therapeutic window compared to many medicines, but its still so small (similar EFFECTIVE dose to fentanyl, 5000% higher LD50) that extreme caution must be taken in dosing. A toxic but nonlethal dose of LSD is gonna leave some bad psychological damage.
>you can eat twice as much Magic Eraser as you can table salt before dying. I have no idea what to do with this information, but there you go.
>you'll die if you drink 10% of your body weight in water. This is pretty hard to do, but there are vanishingly rare cases where people drink so much water that their blood cells explode.
>CBD technically has a lower LD50 than THC? Both are pretty non-toxic, it'd take 70 GRAMS of CBD at once to kill you, and it's usually dosed in MILLIgrams. However, a quarter of the LD50 of THC would be a very very bad time (ever had too many edibles?) while a quarter of the LD50 of CBD would likely just feel drunken.
Hi I'm an actual PhD toxicologist and there's a heck of a lot more to the toxicity of things than the LD50. Lower doses of many of the things on this list may not kill you, but could give you cancer, cause birth defects, and/or cause a host of other health problems. MSG, for example, is less acutely toxic (i.e., won't kill you as fast) as table salt but high doses are linked to adult infertility when exposure occurs in utero.
It's more complicated than just looking at death.
