Please note that Ellen Hahn's claim that 50mg of nicotine is a lethal dose is another lie.

I've never seen any reports (or even sensationalized news articles) alleging that any human has ever died from nicotine toxicity (and I've been looking for evidence for the past two decades).

Besides, its unethical and illegal to conduct human studies to estimate the lethal dose of nicotine.

Also, tobacco workers who harvest the crops are exposed to a lot more nicotine than can be obtained from consuming tobacco/nicotine products, which is called "green tobacco sickness", but I've never seen any reports that any tobacco farm workers have died from their high levels of nicotine exposure.

I think Vocalek posted something about only one person ever dying from nicotine poisoning?
And that was questionable, because they also had a lot of Valium in their system, or something like that?

Elaine, do you want to clarify?

Note: If you decide to use this, give the prize to Petrodus. it was his idea.


Ellen Hahn Says: E-cigarettes use a heating element to vaporize nicotine “and other substances” (deceptively implying that their major use is to deliver illicit substances.)
The Truth: E-cigarette liquid consists mainly of propylene glycol or glycerin, water, and food-grade flavorings (all of which are considered safe by the FDA), and may contain a small amount of pharmaceutical grade nicotine.

Ellen Hahn Says: Cartridges may contain up to 500 mg of nicotine (approximately 10 times lethal dose.)
The Truth: Cartridges range in size from 0.5 to 2 mL, with nicotine content in the liquid averaging 1.8%. German researchers found a maximum concentration of 0.007 mg/m3 of nicotine in the vapor--71 times less hazardous than the OSHA PEL safety limit.

Ellen Hahn Says: E-cigarettes are not a proven cessation aid.
The Truth: E-cigarettes are not intended to serve as a nicotine cessation aid; however they work extremely well as a way to escape from inhaling smoke. Success rates range from 20% for smokers who did not intend to quit up to 80% for smokers who wanted to stop inhaling smoke and sought advice and support from other e-cigarette users.

Ellen Hahn Says: Using e-cigarettes in smoke-free areas may create smoking ban enforcement problems.
The Truth: Vapor doesn’t look like smoke, smell like smoke, or act like smoke. Increasingly, e-cigarette consumers are opting for devices that cannot be mistaken for a combustible cigarette.

Ellen Hahn Says: E-cigarettes may encourage youth to experiment and become addicted.
The Truth: Researchers at Virginia Commonwealth University determined that e-cigarettes have a low abuse potential—possibly because each puff of vapor delivers a fraction of the nicotine found in a puff of smoke.

Thanks Elaine,
I printed that out with the title, "Let's get your fact right, Ellen!" and blew it up....it's going w/ me to Lexington tomorrow!! :)

Oh, btw, Mike Siegel posted again in his blog about the nicotine exhaled from Vapor and Ellen's allegations about it. http://tobaccoanalysis.blogspot.com/
I corresponded w/ him briefly by email today again.
I wished besides the points he made, he also said how much Nitrous Oxide is in ambient air for nicotine to react with...I looked it up... Earth Science FAQs: Why doesn't the Nitrous Oxide in the air make us funny? and it's about 0.000003 percent of the air!!

I also had another idea- since N2O is one of the worst green house gases, whatever nicotine reacts to the nitrous oxide will keep it from floating up to impact our ozone layer by sticking to things- So nicotine is good for the environment too!!

In 27 years of looking through annual reports from the American Association of Poison Control Centers, the researchers found one pediatric death. They found cigarettes in the child's stomach and Valium. Frequency and outcomes of accidental... [Regul Toxicol Pharmacol. 2011] - PubMed - NCBI

There have been a only few adult fatalities, and as near as I could figure out (I admit that I did not check every single one of those reports) these tended to happen with people who stuck on multiple nicotine patches. I read a funny story about that the other day, regarding making sure that the patient understands the instructions. A woman had problems using the patch and called a help line. The suggestion was made that she rotate her patches.

Specifically what this means is that when you take off a patch, put the new one on in a different spot. She took the directions literally. When the doctor saw her, she was wearing multiple patches that she taken off, turned several degrees and then reapplied in the same spot. As far as I know, she was not a fatality.

The reason that there are very, very few oral poisonings from nicotine is that swallowing nicotine triggers vomiting. That's why the directions tell you to avoid swallowing your saliva if you have nicotine gum or a nicotine lozenge in your mouth.

I once accidentally swallowed a chunk of a 4 mg. nicotine lozenge. Within 10 minutes, that piece of lozenge and everything else that had been in my stomach was in the kitchen sink. (The bathroom was upstairs and I was afraid I wouldn't make it.) Within 30 minutes I felt perfectly fine.

I thought Bill was wrong at first too, but he is right in how he explained what she said.
50mg according to her is lethal...500 is 10x that.....so, she said that carts have 10x the lethal dose in them (500mg).
Make sense?

I understand now, but I'd have two questions about that. First, I've vaped 48mg when I was having trouble giving up those last few cigarettes and I really didn't notice much of a difference with 36mg. If 50mg is lethal I should have at least gotten a major buzz. Perhaps if you drank it. Second, is anyone using a 10ml tank?

I think all the LDs are based on oral doses, but I'm not sure.

I believe that's correct. OSHA sets Permissible Exposure Limits (PELs) for chemicals that are inhaled. You can look them up here: TABLE Z-1 Limits for Air Contaminants. - 1910.1000 TABLE Z-1

When I was reviewing the findings of the German researchers on their studies of vapor v. smoke, I consulted their tables of chemicals detected and the quantities, and then I looked up the PEL. In each case, the quantity found in vapor was well below the OSHA PEL. That includes nicotine:

OSHA PEL = 0.5 mg / m3 (one-half milligram per cubic meter)

Concentration in vapor = 7 mcg / m3 (seven micrograms per cubic meter)

To compare, it is necessary to convert to the same scale. Converting 7 mcg to mg yields 0.007 mg.

So the concentration of nicotine they measured is 71 times lower than the OSHA PEL.

Sometimes I find the "Virtual World" a little complicated
with unfamiliar procedures. But I'm old with limited memory space available.
I guess its time for an "brain upgrade" ?!
:p

I've noticed a few loose wires as of late but I figure I'm just using selective memory.

If anyone can recommend a good place to get an upgrade just PM me...........please
