I wonder how they came up with the LD50 of all those materials, like THC and LSD. Is this based on theoretical calculation, in vitro tests, or on a (assumably) very small sample of known deaths?

    Step 1: Feed/Inject mutliple rat populations with different concentrations
    Step 2: See how many die.
    Step 3: The concentration which causes 50% of the population to die is the LD50

    While I was thinking you were yet another user, you were a rat the whole time! Wait, we are all rats!

    Jokes aside, animal testing as a data source seems reasonable to me. Thanks
