Facebook Allowing Marijuana Legalization Ads to Run?

You might recall that Facebook didn't allow ads for marijuana legalization to run, citing the "tobacco" and "alcohol" parts of their advertising guidelines last August.

I noticed an ad earlier this morning and expected it to be gone by now (four hours later). It's still up and running, as can be seen in the screenshot below taken around 10:15AM:

Is this a sign that maybe Facebook has decided that it might be okay to show ads calling for legalization of a natural weed? (Note: Panda Express ad included for munchie effect.)
