Menthol Overdose?

[Duncan]

I’ve just made a batch of Menthol/Glycerin to cut TW Menthol 36mg down to 18mg without loss of ‘Menthol hit’.

Specifically, the volume of Menthol crystals was roughly the same as the volume of two garden peas and I dissolved it in 30ml of Glycerin. Dripping this (just the glycerine/menthol mix) gives a superb strong menthol wallop.

Doing a Google search for ‘Menthol overdose’, I find that it can be toxic if the pure chemical is swallowed. One contributor to another forum suggested that an adult would need to consume a kilo of menthol to be fatal, but no authority for this was cited.

So, I’m minded to think that my mix is pretty safe. Does anyone know anything to the contrary?

The LD50 of Menthol on a Rabbit is 5628 mg/kg, which is pretty high. LD50 median dosage to cause overdose. I cannot find any human information but even the extremely conservative assumption that humans have the sensitivity of a 10kg rabbit. 56g of menthol within 24 hours would be VERY uncomfortable so I doubt you could accidentally do it.

Thanks ratfink. You've confirmed what I expected.

Knowing the LD50 of menthol for a rabbit is a pretty useful bit of trivia knowledge

I'm sure everyone knows that LD50 means "Lethal Dose for 50% of recipients", but if you didn't, then that's two useful bits of trivia!

well... if the average rabbit weighs in at around a kilogram... (I believe its somewhere around there), and it took 5.6 grams to kill that rabbit, and you weigh around 200kg... 200 x 5.6 would be 1.12kg... so that sounds about right.
You know the burnable cd's, how they come in that tower with the plastic lid? Imagine a whole roll of 150 burnable cd's, take that cover off of it and fill it with menthol crystals.... that would be about a kilogram... so take a spoon and dive in! I bet you couldnt do it, lol.

Man... poor rabbit, bet he was feeling frosty on the inside.

Not really pertinent but geez I wish those God awful experiments with animals would stop most tests cold be done without animals.. sorry for the rant but I'm one of those nut jobs that believes its wrong..

P.S. I know i'm a hypocrite but I do eat Kosher meat..

I had a bag of menthol crystals in my wardrobe, waiting to start experimenting when I felt like doing it. They were under some underwear. I thought it might just add nice scent - we often place spare soap there for the same reason. After some time I put on the boxer shorts that were closest to the bag. A minute passed... WHAT THE áíýžíáý IS THAT?!?! It took me a couple more moments to understand what happened, and by that time I could sing Big Balls of Fire better than Jerry Lee Lewis. The menthol was still in the original thick envelope, unopened, in which it was delivered to me from an e-bay seller. It went straight to the bin accompanied by a steady stream of expletives.

Now, that was a completely different part of the body, but...
NO WAY I AM GOING TO PUT *THAT* IN MY LUNGS!

Just a tiny personal experience. Notice there was *no* direct contact with the menthol. It went thought the envelope in form od scent and got to my... er... skin from the underwear. In vaping, it gets *direct* contact with airways and lungs.

Now to the off-topic flame. dcsubburb: God awful experiments saving human lifes/injuries should be stopped? And you eat kosher meat? Like the one where they hang the animal by hing legs, cut its throat and let it slowly bleed to death? Wow...
