what happens to a person when he take KCN[pottasium cynide]?

Answer 1

Inhalation of high concentrations of hydrogen cyanide causes a coma with seizures, apnea and cardiac arrest, with death following in a matter of minutes.

At lower doses, loss of consciousness may be preceded by general weakness, giddiness, headaches, vertigo, confusion, and perceived difficulty in breathing. At the first stages of unconsciousness, breathing is often sufficient or even rapid, although the state of the victim progresses towards a deep coma, sometimes accompanied by pulmonary edema, and finally cardiac arrest. Skin colour goes pink from high blood oxygen saturation.

Answer 2

I hate to just cut and paste, but to be accurate:

The effects of potassium cyanide are virtually identical to sodium cyanide. Once more than 100–200 mg of potassium cyanide is absorbed, consciousness is lost within one minute, sometimes within 10 seconds, depending on the strength of the body's immunity and the amount of food present in the stomach. After a span of about 45 minutes, the body goes into a state of coma or deep sleep and the person may die within two hours if not treated medically. During this period, convulsions may occur. Death occurs mainly by cardiac arrest.

Several prominent Nazis, including Hermann Goering and Heinrich Himmler, used potassium cyanide to commit suicide. The substance was also used in the 1978 mass murder/suicide of more than 900 people at Jonestown, Guyana.
