Animals enjoy drugs just as well as people some times. There's the obvious catnip, and far too many people think it's funny to get their cat/dog drunk/stoned (A good way to lose a shoe when your dog gets the munchies, by the way), but even some insects get into the act. Fruit flies hang around wineries due to their love of alcohol. Confused grain beetles enjoy eating marijuana, and apparently are a large problem for police vaults. One Mexican police department even tried to use this as an excuse to explain why some $200,000 dollars worth of marijuana had vanished without a trace. Um, yeah.
