Stressed elephants at Warsaw zoo to be given medical marijuana

Three African elephants to get liquid doses of the cannabinoid CBD through their trunks. Early trials suggest they like it

The Warsaw zoo has said it will start giving its elephants medical marijuana as part of a ground-breaking pilot project to test how it reduces their stress levels.

Medical cannabis has been used worldwide to treat dogs and horses but this is probably the first initiative of its kind for elephants," Agnieszka Czujkowska, the veterinarian in charge of the project, said.
