Clonazolam (also known as clonitrazolam) is a benzodiazepine that has had very little research done about its effects and metabolism, and has been sold online as a designer drug.[1][2][3][4][5]
The synthesis of clonazolam was first reported in 1971 and the drug was described as the most active compound in the series tested.[6][7]
Clonazolam is reported to be highly potent, and concerns have been raised that clonazolam and flubromazolam in particular may pose comparatively higher risks than other designer benzodiazepines, due to their ability to produce strong sedation and amnesia at oral doses of as little as 0.5 mg.[8]
Legality
Sweden
Sweden's public health agency suggested classifying clonazolam as hazardous substance on June 1, 2015.[9]
United Kingdom
In the UK, clonazolam has been classified as a Class C drug by the May 2017 amendment to The Misuse of Drugs Act 1971 along with several other designer benzodiazepine drugs.[10]
