A national campaign to raise awareness of the dangers of new psychoactive substances (NPS) - so-called 'legal' highs - among teenagers and young adults has been launched by the Home Office.
The radio, digital and mobile phone adverts are aimed at people aged 15 to 21 and warn them about the risks of taking the drugs.
The campaign focuses on the risks and harms associated with a range of legal highs including nitrous oxide, which is commonly known as "laughing gas".
