MOVE SLOW AND SMOKE THINGS: Facebook takes down pages of some legal Alaska pot shops.

The social media giant said its standards describe what users can post, and content promoting marijuana sales isn’t allowed. The issue has popped up over the last few years in states that have legalized recreational and medical pot, often coming in waves, industry officials said.

Cary Carrigan, executive director of the Alaska Marijuana Industry Association, said the industry has been forced to fight the same battles repeatedly as marijuana gains broader acceptance nationally.

The drug is legal for recreational use in eight states, but it remains illegal on the federal level. It wasn’t clear why the crackdown in Alaska happened within the past couple weeks or what specifically prompted it.

Facebook isn’t known for transparency, particularly about what it will or won’t allow users to post.

If your business depends on a social media platform with such capricious content standards, you might want to rethink your customer outreach.
