One of the UK's biggest drug and alcohol charities, CRI, has warned that the UK is "only scratching the surface" posed by Novel Psychoactive Substance (NPS) or 'legal high' misuse.
As part of its new campaign, CRI has launched strangemolecules.org.uk to keep young people informed of the facts as new drugs are discovered every week.
