I have been asked to reply.
There are two primary sources of statistics on the use of illicit drugs by young people: the British Crime Survey (which covers England and Wales) and the Drug use, Smoking and Drinking Survey among young people in England.
According to the 2007-08 British Crime Survey 7 per cent. of young people aged 16-24 reported using a class A drug in the last year.
Latest figures from the 2007 Smoking, Drinking and Drug Use Survey show that 4 per cent. of pupils aged 11-15 years reported using class A drugs in the past year.
