To your actual question yes and no. In the past, yes. Currently no. I think its more the principle. Nicotine, like caffine was evolved by planets as a pesticide. Animals (like parasites) that don't normally come in contact with it, likely don't have resitances to it. Highly evolved Apes like us, are simply to big and evolutionarily advanced to be killed by such a small dose of poison.

A cigarette contains up to a gram of tobacco with a nicotine content of 0.5 to 2 percent. A recent estimate of nicotine's human LD50 is in the range of 0.5 to 1 grams. A four cigarette dose would seem unlikely to be lethal.

  7.2.1 Human data
    7.2.1.1 Adults
      The mean lethal dose has been estimated to be 30 to 60 mg (0.5-1.0 mg/kg) (Gosselin, 1988).
    7.2.1.2 Children
      The lethal dose is considered to be about 10 mg of nicotine (Arena, 1974).
  7.2.2 Relevant animal data
    Dog:     oral LD50:   9.2 mg/kg 
    mouse:   oral LD50:   3.3 mg/kg  (RTECS, 1985-86)
    rat:     oral LD50:   50 mg/kg

0.5-1.0 mg/kg, not 0.5-1.0 grams. Don't go eating cigarettes.

It's a great book. I keep a copy in my scram-bag, as it's the kind of knowledge that could be the difference between life and death, one day.

So you can read the "how not to be eaten by bears" section while being eaten by a bear? If you're going to rely on stuff like that, its best to commit to knowledge and practice.

Oh, I know much of it like the back of my hand, and have spent plenty of time doing outdoorsy stuff, and have found myself in a few genuine survival situations, and I'm here to spout crap opinions on the web still, so...!

It's mostly handy for "was it the one with the serrated leaves, or the one with the smooth leaves which is toxic?".

Good stuff. Glad to hear!

I've been foraging for 25 years so that knowledge is sort of built in (at least in the UK) but I still won't touch mushrooms!

This used to be published as "Survival, Evasion, and Escape" with the same field manual number. I have an old printed copy dated 1969 which includes the missing Evasion and Escape sections.

Doomsday cults missing their deadlines never seem to suffer much harm.

Well, they'd suffer more if they hit their deadlines.

That sounds suspiciously similar to the SERE course the military does: "Survival, Evasion, Resistance, and Escape". "Resistance" entails resisting torture without divulging secrets to the enemy; in SERE training they will actually put you into stress positions and waterboard you, which is where they got the idea to do that kind of thing to prisoners.

That's nowhere near true...

I think the following two paragraphs are very applicable to founders:

It takes much more than the knowledge and skills to build shelters, get food, make fires, and travel without the aid of standard navigational devices to live successfully through a survival situation. Some people with little or no survival training have managed to survive life-threatening circumstances. Some people with survival training have not used their skills and died. A key ingredient in any survival situation is the mental attitude of the individual(s) involved. Having survival skills is important; having the will to survive is essential. Without a desk to survive, acquired skills serve little purpose and invaluable knowledge goes to waste.

There is a psychology to survival. The soldier in a survival environment faces many stresses that ultimately impact on his mind. These stresses can produce thoughts and emotions that, if poorly understood, can transform a confident, well-trained soldier into an indecisive, ineffective individual with questionable ability to survive. Thus, every soldier must be aware of and be able to recognize those stresses commonly associated with survival. Additionally, it is imperative that soldiers be aware of their reactions to the wide variety of stresses associated with survival.
