The UK Government's new drugs information service. The online information is for different age groups, including parents and carers, but is mostly targeted at young people. Generally good info if a little thin and heavy handed on legal consequences. Covers legal and illegal drugs.
There is a free email advice service and a free confidential phone line (that will not show up on bills) on 0800 77 66 00 renamed from the well regarded National Drugs Help Line.
The site has a search feature for locating services in your local area.
