Luohu Customs made the seizure in its passenger inbound channel, where officers found one cannabis cigarette with a net weight of 0.32 grams.[1] Officers were supervising inbound travelers when a woman in white and two fellow travelers entered the customs supervision zone without making voluntary declarations.[1] The woman repeatedly adjusted her shoulder bag as she walked, which officers viewed as abnormal behaviour.[1] Officers intercepted all three for inspection, and when the woman opened her backpack officers smelled a strong suspected cannabis odour.[1] A further search found one half-burned, extinguished homemade rolled cigarette inside a candy box in her backpack.[1]

A field test showed the cigarette’s tobacco was positive for tetrahydrocannabinol (THC).[1] A professional appraisal later found tetrahydrocannabinol in the cigarette and confirmed it as cannabis, with a net weight of 0.32 grams.[1] The case was transferred to the customs anti-smuggling department for handling.[1]

Customs noted that Chinese law lists cannabis among narcotic drugs alongside opium, heroin, methamphetamine, morphine and cocaine and other addictive narcotic and psychotropic substances under state control.[1] It added that smuggling, trafficking, transporting or manufacturing narcotics in any quantity incurs criminal liability and punishment.[1]
