Drug-laced stamps were among the HK$150,000 (US$19,258) worth of illegal drugs seized in a Chungking Mansions flat during a police raid in Tsim Sha Tsui on Wednesday evening, local media reported.
Hong Kong police officers raided the building, well known as one of the cheapest accommodations in the city, at 7pm and arrested a 44-year-old Bangladeshi man, Oriental Daily reported.
Officers seized seven “drug-laced”stamps, 40 grams of crack cocaine, 30 grams of crystal methamphetamine, 100 ecstasy pills, 20 Nimetazepam hypnotic pills, 5 grams of heroin and 500 grams of marijuana, it said.
The type of drug on the stamps has yet to be confirmed, but authorities in many countries have seized similar items.
Officials found that the stamps are coated with a psychedelic drug called 25i-NBOMe, which has similar effects to LSD, but has a higher risk of harm compared with classic psychedelic drugs.
The 44-year-old South Asian man was arrested for trafficking illegal drugs and has been detained while he assists the police investigation.
