Counterfeit 'Xanax bars' increasingly contain flubromazolam or fentanyl

Forensic testing in the US and UK shows counterfeit alprazolam bars frequently contain the ultra-potent RC benzo flubromazolam — active at 0.25 mg — and intermittent fentanyl.

Flubromazolam causes multi-day blackouts and dangerous withdrawal after short exposure.

If you take pressed bars: never mix with opioids or alcohol, and tell someone what you took.

Profiles: alprazolam, flubromazolam, clonazolam.
