[Ideology 1.3.3080] Pawn on food binge smokes joints?

[MoronicCinamun]

This is a weird one, and I'm not sure if it's a bug, but it feels like one.

I have a refugee, whose ideology forbids non-medical drug use.
They also have no overriding traits (i.e. chemical interest/fascination).

They went on a food binge, and for some reason as part of that binge smoked some smoke leaf? They now have a -15 mood from that, as the ideology says. Not sure why they would even smoke it, as far as I can tell the joints don't provide nutrition unlike booze.

Moderator Note:

Thanks for the bug report.  This is intended behavior.  It's not uncommon in real life for someone to do something they would never countenance during a time of emotional stress, and feel guilty for it afterwords.
