The dramatic collapse of Bashar al-Assad's Syrian regime has thrown light into many of the dark corners of his rule, including the industrial-scale export of the banned drug captagon. Victorious Islamist-led fighters have seized military bases and distribution hubs for the amphetamine-type stimulant, which has flooded the black market across the Middle East. "We found a large number of devices that were stuffed with packages of captagon pills meant to be smuggled out of the country," says Abumalek al-Shami, a black-masked Hayat Tahrir al-Sham (HTS) rebel fighter.
