  • Downers
  • Etizolam
  • Rohypnol

Illicit or fake benzodiazepines (often called “street benzos”) have been found to contain some very harmful substances and are causing hospitalisations and deaths in the UK. This includes tablets known as and/or marked with ‘DAN 5620’ (on one side) and ‘10’ (on the other), ‘T-20’, ‘TEM 20’, ‘Bensedin’ and ‘MSJ’, which may contain dangerously potent benzodiazepines, or other dangerous substances not for medical use.
