Yes, the Russians have obviously cleaned it up. I understand the White Helmets obtained video of the Russians bringing in cases of febreze, and Hoover vacuum cleaners. /S

According to the people he spoke to, Douma was a case of aphyxiation (from whatever cause) that was conflated by panic or malice into a gas scare.
This doesn't fit the deep state narrative. Given the suspicious timing of the Douma 'attack', I would bet on a cynically staged event.
Working theory: the White helmets deliberately gassed basement dwellers with carbon monoxide (by burning wood in a low oxygen environment) and then cried 'gas'.
