On 17 January 2020, Customs officers inspected an air consignment declared as loudspeakers arriving from Canada and found about 70 kg of suspected cannabis buds concealed inside 32 speakers, wrapped in tinfoil and vacuum bags.[1][2] Customs valued the haul at about HK$12 million and called it the largest cannabis trafficking case detected at the airport in the past decade.[1][2]

After a follow-up investigation the same day, officers arrested a 50-year-old man suspected of involvement in the case.[1][2] He was released on bail pending further investigation, which was continuing.[1]

Customs noted that cannabis and THC are controlled dangerous drugs in Hong Kong even though recreational use had been legalised in some overseas jurisdictions, and warned travellers against bringing such products into the city.[1]
