If one mills a white powder like potassium nitrate with lead media, the powder will come out of the mill gray. That means there is some lead in the chemical, which will be in the smoke that results from it being burned. That presents a danger of lead poisoning if one breathes a lot of that smoke. But lead media has probably been and will continue to be used more than any other in amateur
