The harmful lead carbonate compounds present in<unk>  caused regular users to experience lead poisoning. Common symptoms of lead poisoning include feeling nauseous, experiencing abdominal pain, high blood pressure and reduced fertility. Exposure to small amounts of lead carbonate can elevate blood lead levels to high levels of toxicity. Long-term use of<unk>  was therefore detrimental to the human body as high amounts of lead were constantly being absorbed by the skin. This caused problems from within, such as internal organ damage which would eventualise in death. It was also thought that regular usage could lead to muscle paralysis and the development of behavioural disorders such as mental confusion and depression.
