mmaddsen -
This is tricky all of a sudden - and hard to explain. There is also a bit of a professional bind here - you quoted my boss (kinda, we are decentralized but share the same governing body).
40-60 mg is the correct estimation for nicotine.
0.3 g has been used for nicotine sulfate as an estimated lethal level. NS is considered far more toxic than nicotine. I have never before seen 0.3 g of nicotine used as a toxic level - so I made the leap to nicotine sulfate, the EPA designated "supertoxic" cousin of Nicotine. That was a bit of an error on my part, after closely reading the referred website, they do indeed mean nicotine. They give a grossly wrong toxic level but nicotine is what they intended.
Nicotine is considered highly toxic by Poison Control but it is not a red flag item - meaning that it is evaluated on a case by case basis, as opposed to methanol which is an automatic ED referral.
So now comes the confusing part - NS, dimethylmercury, & parathion are all rated supertoxic but estimated lethality is greater than 1 g, not much greater but greater. Here my lack of an rPh or chamistry degree shows - I do not really know why nictotine is only highly toxic (EPA level 3) vs NS, DMM, & Parathions supertoxic (EPA level 6). I think it has to do with available forms and ease of exposure.
Nicotine as it is found in plants & products requires a significant ingestion 1 cig
might kill an infant and 5 cigs have killed a toddler (found on autopsy), I have yet to see any data on how many cigs it would take to do in a 70 kg man.
NS can kill with an estimated 6-7 drops on skin!
The data previously quoted does come from an interesting website but quoting a non-govermental web site is still poor form in science/health discussions. I looked closely at the site to see if I could see what was going on. [Note: I missed that the site is referenced up top first time through]. I have no idea where they get the 0.3 g maybe in '93 that was how it was expressed? but 300 mg should kill you, me, SHARK, DocM, Morrus, and PC (although, as mentioned survival has been reported after a 4 g exposure). 0.3 g is still wrong.
The confusing part:
40-60 mg of nicotine = estimated lethal level
0.3g (actually 350 mg) of NS = estimate lethal level
NS = more toxic.
Confusing huh? Maybe a chemist can explain it better?
In the same vein of IANAL, since both my employer and my profession are brought up in this topic - this is not medical advice and on these boards, I do not represent my employer. Strickly IMO ~ just with references.
Further replies will need to be addressed to my e-mail -
eosin_the_red@cox.net. For me, suddenly and by wild chance this conversation has turned professional
, instead of being one of my pet peeves (WAGs presented as fact). But I am happy to address any other questions or problems you have with my assessment, just not where I have to agonize over the legal/ethical implications of what I am posting.
