i believe lead is not very poisonous. its "poisonous" because lead compounds are good chemicals, batteries, and ingredients in high explosives. lead can become bullets, nuclear radiation shielding, and more. its what the militaries use, therefore not for the civilians, because they want the advantage over you.

they take it off the market and make it illegal, and at the same time create a grey area black market, where they sell the lead at gold prices.
