Warning: synthetic opioid in benzodiazepine
In December 2019, we have iWe identified a particularly harmful composition in a sample submitted as alprazolam. Instead of the expected benzodiazepine (alprazolam), we found the new synthetic opioid U-47700 identified.
U-47700 ("Pinky") is a substance from the opioid group, which is sold as a research chemical. As there is only a short history of use and U-47700 is largely unexplored, no reliable statements can be made about risks and long-term effects. It is thought to have similar effects to other opioids, including analgesia, euphoria, sedation and constipation. Animal studies have shown that morphine is 7.5 times more effective[1]. In connection with an overdose or mixed consumption with e.g. fentanyl, the following have already been reported Deaths reported. In the recent past, benzodiazepine tablets (especially XANAX®) have frequently appeared on the black market that did not contain the expected alprazolam, but various substances from the groups of new synthetic opioids or new benzodiazepines[2][3].
We strongly advise against the use of untested benzodiazepines that have not been prescribed by a doctor!
