Last January, the U.S. Postal Service announced it was banning possibly controversial images from appearing on custom stamps. This included things such as alcohol or weapons. But now the Postal Service is backing off on those restrictions, except for one thing: marijuana.

When the Post Office announced their list of prohibited custom stamps last January, they included a wide swath of possibly controversial items. They said the stamps could not contain, "Any depiction of alcohol; tobacco; controlled substances, including but not limited to marijuana; gambling; or firearms or other weapons."

Seems reasonable. But then the Postal Service decided to back off that policy. Now they are allowing "incidental depictions" of alcohol, tobacco and weapons. What does that mean? Well, for example a stamp could feature a couple giving a wedding toast with glasses of champagne or an image of a soldier holding a weapon. 

However, the "incidental depictions" does not include marijuana. Cannabis and other controlled substances are still banned from appearing on custom stamps. 

This isn't the first time the U.S. Postal Service has gotten involved in marijuana politics. In 2015, the Post Office said they would not deliver any mail that contained advertisements for marijuana, including newspapers. This upset several members of Congress who represented legalized states, saying it would hurt businesses in their jurisdictions.

On the bright side, in a few years all our mail will be delivered by Amazon drones, so none of this will matter.
