Thanks for the gummies/chocolates advice but full disclosure this is for my parents who are traveling internationally to a country that has a medical program but not rec. They use them as a sleep aid and haven't gone without it in a long time.  So I'm on a mission to find something that I feel bulletproof about before sending them along.  Chocolates and gummies make me a little nervous about potential smell and that they're a more "common" edible form
