After exposure, cyanide quickly enters the bloodstream. The body handles small amounts of cyanide differently than large amounts. In small doses, cyanide in the body can be changed into thiocyanate, which is less harmful and is excreted in urine. In the body, cyanide in small amounts can also combine with another chemical to form vitamin B12, which helps maintain healthy nerve and red blood cells. In large doses, the body's ability to change cyanide into thiocyanate is overwhelmed. Large doses of cyanide prevent cells from using oxygen and eventually these cells die. The heart, respiratory system and central nervous system are most susceptible to cyanide poisoning.

That's an interesting question, NeverMind, and I didn't know the answer. As it happens cyanide poisoning is a little like being suffocated because it prevents the body's organs from using oxygen, and they shut down.
Typically, an acute ingestion will have a dramatic, rapid onset, immediately affecting the heart and causing sudden collapse. It can also immediately affect the brain and cause a seizure or coma.
Small amounts taken over a longer period are likely to cause symptoms like altitude sickness.
never mind, your preoccupation w/death is really starting to WORRY me! whatever happened w/your friend who was talking about ending it all? is this question for him or you or both? i think you need to speak w/a professional! REALLY, your starting to scare me! Please, talk to someone, or me, i'll listen! truly. it gets better!!!!!!!
I am inclined to agree with wwtthh on this and was wondering why this aspect of the question had not been addressed. Whatever it is that motivated you to inquire about this poison I can only say that if you plan on using it to do harm to yourself or a friend, just give it one day more before final decision. I've had some pretty bad times in my own life when it seemed like the only sensible way to stop all the pain. Luckily I had a friend that sat that one more day out at my side. Looking at it now I realize that when all seems hopeless it is only my heart and mind giving in to those negative feelings. Nowadays when i think about how truly fortunate I am, one thought comes to my mind and it goes "Isn't life wonderful?"
