In the first half of 2013, security services in China seized about 4.1 tonnes of heroin across the country. The amount seized was 12.5 percent higher than the amount seized in the first half of 2012. 6 tonnes of ketamine, an anesthetic drug primarily used by Veterinarians, were also seized during the time period, an increase of 311 percent from the year before.
In terms of traffickers, roughly 81,000 people were arrested by police across China in the first half of 2013 for drug related offenses. The number of people arrested was 34 percent higher than the year before.
According to the United Nations Office on Drugs and Crime, the demand for heroin and opiates in China has increased to exceed the supply in Laos and Myanmar, causing traffickers to have to transport opium for Afghanistan to meet the demand.
