The Warsaw Zoo will study the effects of CBD-rich cannabis on its three African elephants, according to Agence France Presse. The research is meant to gather data on how CBD affects elephants’ stress levels. CBD oil will be administered to the elephants through their trunks.

"This is probably the first initiative of its kind for elephants," Warsaw Zoo veterinarian Agnieszka Czujkowska told AFP. "It's an attempt to find a new natural alternative to the existing methods of combating stress, especially pharmaceutical drugs.”

As the AFP notes, the three elephants recently experienced the death of the zoo’s alpha female, something that has caused angst among the small population. Czujkowska told the news agency that data may be available on this study sometime about two years from now.
