It has long been known that Assad has flooded the Middle East with the drug Captagon (a type of methamphetamine).

It is no secret that the Russian army in Ukraine is struggling to survive on alcohol and has long since switched to the almost universal use of stimulant drugs, as has been mentioned many times in Russian military blogs.

The availability and cheap price of "Map" (Captagon) in the Russian army most likely indicates that it is Captagon that comes from Assad's distribution network, with a production cost of only one cent per pill.
