In a word, no. Not even in state.

Every year around the Holidays, the US Postal Service issues a reminder not to mail marijuana to your friends, as Federal law still considers it illegal, and the Postal Service is a quasi-federal government agency, so they're obliged to report pot found in the mail.

I know what you're thinking. 'Yeah, I can't mail reefer to my friend in Ohio, but I can mail it to my buddy in Lansing, right, because we're both in a state where weed is legal, right?'

Nope.

While most jurisdictions aren't going to bother themselves with a minor marijuana case, the Feds might, so why risk it?

According to an article in Hail Mary Jane, the marijuana web site:

The USPS is an agency of the federal government, so it must obey federal guidelines to the letter. Under U.S. Code 1716, it’s a felony to use the U.S. Postal Service as a method for mailing marijuana, even within the territorial limits of pot-legal states

The bottom line is this – you’re still committing a crime anytime you’re mailing marijuana.

If you leave in some of the medical states, you should check the best weed delivery services as an alternative to mailing edibles or weed.

That being said, that same article offers suggestions on how to wrap a package up and possibly get it through the mail, but that's on you. I've warned you the best way I know how.
