West Kowloon Station Customs intercepted an inbound male traveller who entered the customs control area without declaring anything and behaved unusually at the checkpoint.[1] The traveller kept playing with a mobile phone in his right hand while fumbling in his pocket with his left hand as he passed through customs.[1]

Officers found two suspected cannabis e-cigarettes in his right trouser pocket and one each in his left trouser pocket and his toiletry bag, four in total.[1] Customs recorded the four e-cigarettes as weighing 67 grams gross.[1] A specialist agency later confirmed that tetrahydrocannabinol (THC) was detected in all four e-cigarettes.[1]

The case was transferred to the customs anti-smuggling department for further handling.[1] Customs noted that Chinese law lists cannabis among narcotics and that smuggling, selling, transporting or manufacturing drugs carries criminal liability regardless of quantity.[1]
