Topic: the lethal dose of caffeine (23 msgs / 537 lines)
1) From: Gary Townsend
I was just doing a little constructive research, and found this little tidbit:
According to the caffeine FAQ (http://www.seas.upenn.edu/~cpage/caffeine/FAQ4.html#1) the lethal
dose of caffeine is 10 grams, which translated into 50-200 cups of
coffee, which would have to be consumed at one sitting. You would be
throwing up from overindulging well before you could drink enough
coffee to kill you.
Note, however, that the side effects of caffeine include nervousness
and rambling thought and speech patterns.
*** That would explain a lot of the late night posts here lately***

I recently read a story of a young man who consumed about a pound of coffee 
beans and was near death from the caffeine.

Just to put it in  a context you can comprehend, that would be about 6 
pints of espresso.  I have done six pint of Guinness in a sitting, but six 
pints of espresso - whoa and shudder :-)

I have actually heard the lethal dose is much lower - around 1 - 4 grams 
for an average human, according to erowid. As "lethal dose" measurement 
goes, stating the mass of a substance is generally considered wholly 
inaccurate. Far more accurate are the following:
"LD50" - an amount per kilogram of body weight which will kill 50% of 
test subjects.
"TDLo" - smallest amount per kilogram of body weight which produces signs 
of toxicity. "Lowest Published Toxic Dose".
"LDLo" - smallest dose per kilogram of body weight which has been shown to 
be lethal. "Lowest Published Lethal Dose".
A quick web search pulls up figures for caffeine in rats which puts the 
LD50 around 192 mg/kg. Figures for humans seem hard to come by and vary 
widely, but there are some TDLo figures around 3276 mg/kg and LDLo for 
humans from 7 mg/kg - 1000 mg/kg. All of these figures are for oral 
ingestion.
For reference I weigh 86 kilograms (190 lbs) which puts my theoretical 
lethal dose between 602 mg and 86000 mg.

Found this info at this website, and always wondered if 'coffee kills'.http://www.madsci.org/circumnav/index.htmlSo, thanks for the research, Jason...I learned something usefull today.

Also was looking at this:http://www.madsci.org/posts/archives/2000-12/977273296.Ns.q.htmlexcerpt:
It turns out that adenosine increases most in the part of the brain
that is most directly linked to memory, and that increased adenosine
causes memory failure. Putting this all together, we show that
adenosine increases during the day, and that increased adenosine
hinders memory. This being the case, you can start to make a
hypothesis about when people's memory will be the best!
Interestingly, caffeine, which is in Coke and coffee, blocks adenosine
from doing its job. So, as you may know, Coke keeps you from falling
asleep. But people have also found that the caffeine in Coke can
temporarily improve your memory (perhaps by increasing your level of
attention). But an IMPORTANT NOTE is that you shouldn't drink lots of
Coke to improve your memory; caffeine is a drug, and is addictive if
you use it a lot. And that is something you absolutely do not want. A
little bit of Coke every once in a while is ok, but if you have are
having one or two cans every day, that's not good!! Also, sleep is
critical for memory, so trying to stay awake for a long time is
actually bad for your memory!
I can't vouch for the validity of ANY website, but it does help me
consider subjects near and dear to my heart. Coffee. Sleep. Memory
Loss. Living better. Saving money.

People who drink coffee will die someday...
People who do not drink coffee will die someday...
Let's drink coffee and die someday...
This was the logic shared with me regarding smoking some 30 years ago.
 I didn't end up becoming a smoker, and am very thankful.  But you
cant wrest the coffee mug from my hands...
Thanks Gary - the actual science is very interesting...  I assume
these are guidelines and every body is somewhat different, such that
the effects will be greater or lesser on an individual basis?
Like, I lost my mind a long time ago?  Blaming the coffee may only be
convenient!

Brett

While it's difficult to consume enough coffee to die from caffeine
poisoning, coffee isn't the only place caffeine is found nowdays.
There are a lot of caffeinated items, from the old faithful No-Doz
through to candy, mints, fudge and even soap.
Some even boast of their high caffeine content. eg: Foosh Energy Mints
"Each mint has 100milligrams of caffeine - that's 25% more caffeine than
in a Red Bull."
A couple of tins of those, washed down with Bawls caffeinated water
could easily be quite harmfull.
The moral of the story, of course, is to to get your kids
to avoid strange candy and stick to good single-origin double 
espressos ;)

Does roasting soap change its chemistry in any way?

Soap roasting is, I believe, an ancient skill shrouded in the mysteries
of time.  But I did find this:http://www.ineedcoffee.com/02/11/soap/If I use freshly brewed coffee, will the soap smell more like coffee
without the addition of the oil?
No, I don't think that has an affect. The actual coffee doesn't scent
the soap - - only the oil scents the soap. The coffee will make the soap
a caramel color, and if you add coffee grounds at the trace stage the
coffee will make the soap a heavy-duty soap. However, if you want a
darker brown color to the soap you'll need to use the crayon.

Incredible!  So much for joking - this is great....  I will be making
some soap, and the traditions are sure to follow...

I certinly don't think my language has warranted a mouth-washing...
Some have complained of my posting, and occasionally someone disagrees
(Say it isn't so!)...
But if I ever open up a can of coffee again, I just know the tainted
odor might cause me consternation, and thus the need for soap...
Oh, and did I mention I have 7 boys...

Seven boys?  Great Googly-Moogly!  There's no way to even write that down 
properly.  I don't know whether to offer respects or condolences.  As the 
father of just one girl (girls really are better, by the way) that taxes 
all my limited parenting skills, I think I'm just stunned.
If they are anything like the boys-with-brothers I have known, you will 
either be supported handsomely in your old age...or they'll *never* find 
your body.  Here's hoping it's the former!

All the little jobs get done; 
Weddings - we're with the groom;
There's always someone going through a voice change...
On the other hand,
There's always a babysitter so Deb & I can go out!!!; 
They cook, clean and do their own laundry;
We can drop in for a month, and when we're done, we'll move to the
next kid's house;
None of these kids thinks they're the center of the universe;
They are learning they ARE their brother's keeper;
Learning to share;
Unlimited testosterone;
and finally, Debbie is a Queen surrounded by princes...
You guys are the best group I know!
