There have been a number of instances of young people passing out and even hospitalised after the use of certain vape pens believed to contained CBD (Cannabidiol) or Spice. There is little research around the long-term effect of any vape and it is illegal to sell vapes to anyone under 18 years old - that includes young people selling vapes to their friends. However, while CBD vapes are legal in the UK (provided that the THC content is under 1mg per container (bottle/cartridge), not 0.2% which is a misinterpretation) it is important that children and young people are aware of the potential dangers of these vapes. 

There is lots of research about the benefits of CBD for a range of health issues, including mental health and anxiety and partly because CBD is suggested to be most effective when vaporised. However, while young minds are developing any mind altering product can have a detrimental affect on children and young people specifically.

In some areas in London, screening arches are being utilised in schools as a deterrent to ensure young people are safe, particularly in schools.

UPDATE: Police dealt with a serious incident at a school in London on 29th January 2024 where 5 pupils ingested a small drop of red liquid and fell seriously ill. Thankfully they recovered well. The Police believe the students thought they were consuming THC vape oil and have recovered the substance and have submitted it for testing. Students are reminded of the potentially harmful effects of illegal drugs and particularly, at this time, a currently unidentified red liquid which may well produce fatal consequences if ingested.
