Heroin, also known as diamorphine, is an opiate drug that is synthesized from morphine, a naturally occurring substance extracted from the seed pod of the Asian opium poppy plant. It can be injected, snorted/sniffed, or smoked, all of which rapidly deliver the drug to the brain. Once in the brain it is converted to morphine and binds to receptors known as opioid receptors - primarily those involved in the perception of pain and in reward - often resulting in addiction.
Heroin swoop nets two
POLICE yesterday smashed a drug-cutting centre in Quarry Bay with the seizure of 30 kilograms of caffeine and 12 kilograms of high-grade heroin worth more than $10 million.
Two men, aged 29 and 43, were arrested when narcotics officers broke into a flat in Kornhill yesterday morning.
Police found on the premises equipment such as hammers and mixers used to cut the drugs.
Senior Superintendent Tang Hau-sing said it took one month to collect intelligence and investigate information before they took action yesterday.
He believed there were still people at large and the investigation was continuing. No one has been charged.
''We believe the drug was imported via China for local use. The drugs are very high-grade, with over 90 per cent purity,'' he said.
This is the first time this year a drug-cutting centre has been smashed on Hong Kong Island.
