In October 2018, police in the city of Yueyang in Hunan uncovered a drug trafficking gang involving disabled people. The gang smuggled drugs from abroad via southwest China's Yunnan Province to other places in China including Hunan, Hubei, Inner Mongolia Autonomous Region and Zhejiang.

In March, police in the cities of Yueyang, Hengyang and Changsha in Hunan carried out investigations, discovering the smuggling channels and structure of the gang.

During May and June, the police arrested 135 drug addicts and seized the drugs, including heroin and methamphetamine.

It is one of the largest drug smuggling cases ever uncovered in Hunan, according to police.
