Hopefully this link works.
This is what I found interesting (among other things):
A small number of postmarketing cases report gabapentin misuse and abuse.[1] Although the rationale for abuse is unknown, some individuals describe "euphoria, improved sociability, a marijuana-like 'high', relaxation and sense of calm."[1] Other patients report feeling "zombie-like."It talks about how Gaba has been reported being misused in correctional facilities (if I was in jail I think I would want a drug escape as well). It also talked about how it is easy to get an early refill because it isn't a controlled substance and that is why some people would take more than prescribed (between 3600-4900 and 1800 mg/day was prescribed), and then the script would run out and then the withdrawal symptoms set in.
Again, I think you have nothing to worry about, but I just thought it was interesting that it was being abused in jail, it is not a controlled substance, and it can give a buzz like MJ. BUT, that is not everyone nor the norm.
I did read a drug abuser blog and he abused gaba (along with some other drugs) after he got out of rehab. He did say that coming off of it wasn't as bad as heroin, but he was surprised how crappy he felt without it. Again, he was using more than the normal amount (his grandmother was on it for her arthritis which is a higher dose) that would have been prescribed.
