What is a therapeutic index (TI for short):

TI is a way of gauging a substance toxicity. It can be calculated in two different ways:

  • LD50 / ED50
  • TD50 / ED50

LD50: lethal dose in 50% of the test population

ED50: dose to achieve desired effects (in this case experiencing pyschoactivity) in 50% of the test population

TD50: dose to experience toxic effect in 50% of the test population

​

In this case all the values are calculated using the first method.

Keep in mind that the substances used are pure and in a lab environment.

Addressing inaccuracies:

As you might imagine calculating the TI of a given substance for humans is pretty hard, this data is based on animal studies and estimates based on death reports, so it might not be incredibly accurate. Also the therapeutic index calculated this way doen't directly measure how toxic a substance is for your body, although a broad therapeutic index generally implies a less toxic substance.

(?): since it's unknown if these substances can cause death in humans it's really hard to calculate their TI

(*): LD50 are all over the place for this substances, this is the best i could find.

That’s just it. It DOESNT show how massive apples market cap is via a comparison for perspective because the comparison is invalid.

It just shows apples market cap and then a separate number next to it. No perspectives obtained from a comparison.

This is a very odd comparison. It's similar to compare someone's net worth to someone else's yearly salary, doesn't really make sense. One is accumulated wealth over time, the other is how much they make in given year.

Since the OP haven't provided sources and explanations in the comments, here we go:

Therapeutic index isn't the same as toxicity. It describes how easy it is to 'overdose' and and used to measure how safe a drug is in terms of dosage.

What is doesn't describe is how much damage a drug can make to a body, how severe side-effects may be or how quickly you can become dependent on the drug.
