Probably is illegal for federal employees, but unless you're in a position for random drug tests like an equipment operator or law enforcement, probably could get away with it.  I've used marijuana chocolates a couple of times: I have some pretty bad shoulder pain, didn't do much for me.  We also tried CBD oil when it became legal here, found it to be an utter waste on me.  My wife thought she had benefit from it, and she demonstrated it was effective for calming our more nervous dogs when needed.
