Plausibly Rohypnol and GHB are on the list of substances bees and wasps can be trained to detect. Unlike drug-sniffing dogs, bees and wasps can only be trained on a single scent and are less influenced by their handlers, so it’s less of a privacy invasion and you can worry less about accidentally detecting drugs you don’t mind. My impression is the bees need to be in a cylinder that’s held fairly close to the source of drugs, but I really really want your friend to release trained roofie hunting bees into clubs where they swarm rapists, Jupiter Ascending style.
