Paracetamol is commonly used for self poisoning, and the costs of treating the resulting liver failure in the

tablets, but this would mean that the millions of people who take paracetamol responsibly would have to
take methionine unnecessarily. Alison Jones and colleagues and Edward Krenzelok debate the issue.
