Risk assessment

This tablet, sold as Xanax, did not contain the expected benzodiazepine alprazolam, but flubromazolam.

Flubromazolam is a very potent New Psychoactive Substance (NPS) from the benzodiazepine group and has never been researched and approved for human use. Flubromazolam is dosed lower and has a longer duration of action than the active substance alprazolam contained in Xanax. For this reason, there is a risk of overdose if these substances are misdeclared. Flubromazolam has an even higher dependence potential compared to other benzodiazepines.

Flubromazolam is an unresearched substance. There is hardly any reliable information on risks, toxicity, side effects and long-term consequences.

Mixed use with other depressant substances and dissociatives (e.g. ketamine) can lead to unconsciousness and a life-threatening respiratory depression. Medications purchased on the Internet are also often misdeclared; always have them tested before use!

Consumption is discouraged.

Alert level

Safer Use


Have your substance tested in a drug check if you bought it on the black market or on the internet. Counterfeit blisters may look identical to the original packaging.

Mixed use

Do not mix any depressant substances such as benzodiazepines, alcohol, GHB/GBL or opioids. Risk of unconsciousness or respiratory paralysis!


Feel your way to the dosage and do not rely on dosage information from friends. Various factors such as habituation or dependence can contribute to a greatly increased dosage!


If you do not have the possibility to have substances analyzed, first test a maximum of one third of the pill. Some counterfeit drugs contain a more potent substance than the original.

Wait and see

Wait at least 2 hours after taking the drug. With some drugs, the onset of the intoxicating effect is very slow or it is difficult to perceive.
