Orally, KCl is toxic in excess; the LD50 is around 2500 mg/kg (meaning that a lethal dose for 50% of people weighing 75 kg (165 lb) is about 190 g (6.7 ounces), or about 38 teaspoons). Table salt is about as toxic. Intravenously this is reduced to just over 100 mg/kg, but of more concern are its severe effects on the cardiac muscles; high doses can cause cardiac arrest and rapid death, ergo its aforementioned use as the third and final drug delivered in the lethal injection process.
