Depends where you are, Alprazolam is rarely prescribed in a lot of European countries , diazepam and lorazepam very commonly.
Right. Perhaps I'm guilty of putting too much "American" into what I post, as I was actually aware of the prevalence of Diazepam in European Countries. Sometimes you just choose the voice that you think will be most helpful to most people. The commentary regarding the commonality of Diazepam prescription was secondary to our primary goal, which was to address the differing potency of two Benzodiazepines. I hope that clears things up.
I have been out of the game, as it were for a couple of years now. I had my days where I could tell you the name of a person based upon the drugs they were prescribed and I could make a mental map, if you will, of my own area of the states. At the time, Diazepam made up at most 10% of prescriptions available for purchase on the street at any given time, with Alprazolam and Lorazepam roughly equal at 40% a piece, while occasionally you would encounter odd-balls like Oxazepam (Serax) and these would account for the remaining 10%. This is all completely hypothetical and doesn't even reflect any and all prescriptions. For instance, folks who are on maintenance therapy for Epilepsy or Traumatic Brain Injury are not often out selling their medication.
I'm just saying, there is some variability. What might be helpful to my friend in New York City might not apply to someone in Derry. We can only try to do our best and use our mutual accessibility our advantage. It has worked pretty well so far.
Edit
There's a pretty cool documentary on Youtube about an alleged Diazepam/Pregabalin epidemic in, I believe it was Northern Ireland. Who knows how true it is, but they had street dealers with Pregabalin dealers and they called them "buds".
I was moving too fast and forgot all about Clonazepam. When I was talking about availability, it was more like Clonazepam/Alprazolam/Lorazepam being prescribed at pretty much the same rate. This is all just my opinion and my experience.
