Etizolam is a benzodiazepine analogue. It has gathered some popularity on the new psychoactive substance (NPS) market in the UK and Europe. It has a broadly similar pharmacological profile to benzodiazepine drugs such as diazepam. A 1mg tablet is equivalent to a 10mg diazepam (Valium) tablet, so about ten times the strength.
NOTE: Etizolam is now controlled under the Psychoactive Substances Act 2016
