Amy, a 22-year-old dancer, says she used to be a regular customer of the drug delivery service. She spent about HK$500 - and sometimes as much as HK$1,000 - every day to have cocaine delivered to her home on Hong Kong Island. 'It's just like making a call and ordering a milk tea from a restaurant,' said the young woman. 'I would give them a call and they would deliver to my door. Sometimes, they would arrive within five minutes.' Amy became an addict at the age of 18 after trying out drugs with friends at a party. Later she got a phone number from a friend and began ordering drugs from two dealers who lived in the same district. 'Sometimes the dealers would take the drugs with me and my friends at my home,' she said. 'The delivery service did give me a sense of security. I did not need to worry about being caught in the middle of a drug deal in a public place.' However, the drugs took their toll. Amy lost her appetite, grew weak and was unable to work. Finally, after three years of drug abuse, Amy sought treatment. She quit drugs in March.
