Okay, so I've found out that quick lighting charcoals are Kosher for Passover but for the body? I only use quick lighting charcoals these 8 years, my pet peeve in smoking. And I know that much of them are mass produced in China. Anything goes there, (almost) they found some dangerous substances in medicine and another time in children's toys. After trial they were sentenced to death!
