Racetam's are not new medications. There are numerous Racetam analogs in circulation at this time. There are some that are used in medicine like Levotiracetam (Keppra) and there are myriad used in the "supplementing" community, where they are often touted as drugs capable of improving cognition. I don't know if the term "smart drugs" is still being thrown around, but if so, Racetams would definitely fall into this category. Many are not controlled by any kind of laws so are traded openly on the internet.
I would be super-duper surprised to find that a Racetam would be effective in reducing the intense negative symptoms of Benzodiazepine withdrawal. I seriously doubt it man. I can see how perhaps a "smart drug" could have a place in the long-term plan for a person's recovery. For instance, we know that among other things, Benzodiazepine withdrawal interferes with the efficiency of our though process, emotions etc. If this drug truly did what people say it does, it could be helpful in the weeks or months that are involved in fully regaining homeostasis.
If you're looking for something to help you get off Benzodiazepines, we can help you with that. There are lots of threads out there already and you're free to start your own as well. We'd be happy to help you out. It's not an easy process, but with help and dedication, people get out of this situation that you're in.
