He was only 13 when he started as a drug runner, selling Ice, or methamphetamine, to abusers.
Shockingly, Bobby (not his real name), who is now 18, told The New Paper on Wednesday that his supplier was none other than his father.
He also got Ice as a bonus from him.
The slim, tan-complexioned teenager is now one of 37 residents, who are aged between 16 and 60 years old, at the Breakthrough Drug Rehabilitation Centre in Selangor, Malaysia.
Its coordinator, Mr Samuel Krishnan, 48, said that more than half of them are former drug addicts.
In 2003, Mr Samuel co-founded the facility at Petaling Jaya, about an hour's drive from the Kuala Lumpur city centre.
He said that he has heard of drug runners who are as young as 12 years old.
Drug dealers tend to approach youngsters at places like playgrounds and other hangout places before tempting them with the lure of easy money, he said.
"Some of these kids are still in school while some are dropouts. Drug dealers like to recruit minors to prevent detection. These youngsters could make quite a lot of money selling and delivering drugs. They can earn up to RM100 (S$40) a day."
Separately, TNP also spoke to a former Singaporean drug abuser who used to work in KL for five years.
Leo (not his real name), 41, said that drugs there were just a phone call away and dealers are known to operate in clubs and parties like the Future Music Festival Asia, held at KL's Bukit Jalil Stadium last week.
