The New York Times reported in December 2021 that the Syrian Army's elite 4th Armoured Division, commanded by Maher al-Assad, whose brother Bashar al-Assad is the ruler of Syria, oversees much of the production and distribution of Captagon, among other drugs. The unit controls manufacturing facilities, packing plants, and smuggling networks all across Syria, and had started to deal in crystal meth.[14] The division's security bureau, headed by Maj. Gen. Ghassan Bilal, provides protection for factories and along smuggling routes to the port city Latakia and to border crossings with Jordan and Lebanon.
