was Janice snorting coke at thanksgiving in the episode "The Telltale Moozadell"?

I'm not sure how her character will develop so I'm guessing this is a hint on something that's about to come but I found it really odd even so.

right after that guy who keeps faling asleep gives a rant about how people shouldn't drink, Janice nods at him but Tony flashes her a signal like she's just snorted a line and has some white leftover on her nose;

couldn't she resist a line over a family dinner? and while I knew it couldn't last much long, I was buying her born again christian mentality
