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 2006-07 British Crime Survey 10.6 per cent of males and 5.5 per cent. of females aged 16-24 reported using a Class A drug in the last year.
Figures from the most recent smoking, drinking and drug use survey, which was carried out in the autumn school term of 2007, show that 3.8 per cent. of male pupils and 4.2 per cent. of female pupils aged 11-15 years reported using Class A drugs in the previous 12 months.
