Syria: Inside Captagon drug factory which funded Assad’s brutal regime

It's been called the poor man's cocaine. Captagon: the drug that funded Bashar al-Assad's brutal rule in Syria. It's an amphetamine which - in high doses - induces feelings of euphoria and invulnerability. Popular with soldiers, they say it offers 'chemical courage' and reportedly suppresses pain. And it's made the Assad family billions - more than 10 billion dollars a year, by recent estimates. Money it used to shore up a crumbling dynasty.
