They are 21 and younger.
Indeed, one in five of those arrested for drug abuse in that age group is a student, the Central Narcotics Bureau (CNB) told The New Paper.
More young abusers aged below 20 were arrested last year –- from 79 in 2007 to 257 last year.
That’s not the only sobering statistic.
Those aged 16 and younger accounted for 64 of the youngsters arrested for drug abuse last year compared to 15 in 2007, posting the largest percentage increase.
It’s a worrying trend, said Mr Masagos Zulkifli, Minister of State for Home Affairs and Foreign Affairs at CNB’s workplan seminar yesterday.
