No, probably not.
First of all, Buspirone has no real recreational value. I'm assuming that you are prescribed this medication as it's not really a substance that one would buy off the street (unless one were to be scammed by misrepresented "Xanax Bars" that are actually Buspirone). If you are getting anxiety relief from taking it on a day to day basis, more power to you, but there won't be any synergy between Buspirone and Benzodiazepines. You will just feel each substance's effects in their own right.
