Sure I read somewhere that the Sami have used them to catch wild reindeer. Slaughtering the animal while it is in a catatonic state and reserving the urine to use as a refreshing beverage. The story went that the compounds that cause the more unpleasant side effects (catatonia and nausea) get processed by the reindeer's systems and the more desirable compounds get passed through into the urine. Adds a whole new angle to getting p***ed, but if it helps you get through the arctic winter, who am I to judge.
