I try to stay out of "Reefer Madness" threads but you need to source that statement. I have no clue what a millier is.
Once upon a time, I thought Reefer Madness was ridiculous over-the-top hyperbole. Now, I am not so sure.
For references on LD50s, unfortunately, most of the scientific articles are behind paywalls. However, according to the abstract of the article referenced below, available at Elsevier, the LD50 of THC in mice is 276 mg/kg, which equates to about 21 grams in a 165 pound person. Reply #30 in this thread quotes an article that estimates LD50 in humans as about 2 grams for an adult. (It is common that LD50 varies between species).
A millier is the result of the auto-uncorrect function of my iPad. I had typed milliliter, which is about 1/28 of an ounce. This would be slightly more than a gram of THC.

I think it's a thousand "ers".
