I'm aware xanax is produced in the UK by a company named Pharmacia Limited, presumably being where most of the xanax purchasable on the street originates from. Are there methods of verifying legitimate xanax bars (the 2mg pills) compared to items which are not really xanax? I think there would be understandable paranoia surrounding what's in these pills if you were not able to obtain them via the NHS; it could be poison or anything. In another thread I made I inquired as to this but apparently discussing harm reduction by means of obtaining substances in a way that is safe (through the NHS) is not allowed on this website and the thread was closed, so if this thread is also in violation of these rules then I apologise, but prescription drugs seem preferable to buying God-knows-what via the streets in regards to harm reduction. However if that is what is necessary then again: are there methods of verifying the legitimacy of street-bought xanax, ideally inexpensive ones? I'm aware of similar things around the testing of MDMA but I haven't heard of anything in regards to benzodiazepines.
