Chemical weapon for sale: China’s unregulated narcotic

For a few thousand dollars, Chinese companies offer to export a powerful chemical that has been killing unsuspecting drug users and is so lethal that it presents a potential terrorism threat, an investigation has found.

The AP identified 12 Chinese businesses that said they would export the chemical a synthetic opioid known as carfentanil to the US, Canada, the UK, France, Germany, Belgium and Australia for as little as $2,750 a kilogram (2.2 pounds), no questions asked.
