Phenazepam (fen-a-ze-pam) also known as Bonsai Supersleep is a medicinal drug from Russia and has been available in Europe for the past few years as a research chemical. It is mostly produced in China and sold in pure form via the internet. Originally branded a ‘legal high’ it is now illegal to possess and/or supply it.

Phenazepam is a very long acting benzodiazepine (downer) drug which has a sedative effect and can cause long periods of sleep and drowsiness. It also slows down your heart rate and breathing.  People using it can feel calm and relaxed with reduced feelings of anxiety as well as experiencing short term memory loss, reduced mental alertness and double vision. 

It usually comes as a white/off white crystalline powder or as a liquid which is swallowed either in capsules or added to ‘blotters’ (small pieces of paper).  Phenazepam is very strong and first time users (even those with experience of other benzodiazepines) should not take more than 0.5mg which is the equivalent of 2000 doses from a gram of powder.  These doses should not be taken as recommendations.
