Sadly, you are going to see more and more prescribers behaving in this manner. I work in an environment where I am hearing about it more and more, often from doctors themselves. The days of requesting benzos and getting them (not saying that is what happened here) is largely over, at least when compared to previous times.
And of course this has much to do with liability and preserving one's license to practice medicine and risk management in general. In addition, the medical model is dictating that even prescribing benzos at all, under formerly common circumstances/conditions, is becoming slowly phased out except in the most "extreme" cases. They did it with opiates, and they are now doing it with benzodiazepenes and have been for several years. In addition, I would speculate that in the future, you will see a major crackdown on the internet-based drug trade and research chemicals. Again, just speculation, but I would suggest that the trend of "easy access" to drugs on the internet is absolutely going to change. Not today or tomorrow, but I will say that I believe that easy access to drugs, again, via the internet, will end eventually be targeted. I believe the clearnet markets will be targeted first, at least when compared to how relatively easy it is to acquire them now. I also believe that moving forward, there will be blanket bans of many chemicals that are fairly easy to obtain currently. It can't be stopped entirely, and never will, but I do believe that a crackdown will occur in the future. I just mention it because everything that I have been observing for many years keeps leading me to that conclusion, so I guess everyone will find out one way or another...
