The elephant, named Xiguang was suffering from heroin withdrawals, luckily he was immediately sent to a protection center in China's Hainan Island. Xiguang, is an Asian elephant and they are threatened with extinction. During his stay on protection island he received daily methadone injections and after three years has completely recovered. In September 2008 he was transferred to the Yunnan Wild Animal Park. Now, that's 3 years of rehab. I couldn't find any information about his condition today...hopefully he's still doing okay.
After reading the story I had a couple of questions? If it took 3 years of rehab for an elephant would it take 3 years for a human to fully recover from heroin addiction too? Also, elephants never forget, so what do you think he thinks about when he sees a banana? Sad story.
