TAIPEI (Taiwan News) – Former Taiwan High Speed Rail Corporation (THSRC) Chair Nita Ing (殷琪) will not be prosecuted for importing marijuana products to treat her dog, reports said Tuesday (April 30).

Customs officials found the drugs inside a FedEx package sent from the United States to Ing’s daughter in Taipei, fostering suspicions Ing was involved in smuggling. She is the former president of one of Taiwan’s largest construction firms, Continental Engineering Corporation. Breaking the relevant law could be punishable by at least 10 years in prison, the Liberty Times reported.

Ing, 69, explained that one of the four dogs at her Taipei home always displayed signs of aggression, so she had bought a type of medicine to try and calm the pet down. She presented evidence of bite marks to investigators.

Friends in the U.S. made recommendations, but as she needed to leave and return to Taiwan before the medicine arrived at her San Francisco home in May last year, she had a staff member send it to her daughter.

The Shilin District Prosecutors Office accepted Ing’s explanation, concluding she should not be prosecuted. The product, listed for consumption by cats and dogs, included Cannabidiol (CBD), an active ingredient in cannabis derived from the hemp plant. Ing told investigators she would not have bought it had she known it contained cannabis.
