We know that, Gabapentin (see structure; brand names Fanatrex, Gabarone, Gralise, Neurontin, Nupentin) is a pharmaceutical drug, specifically a GABA analogue. It was originally developed for the treatment of epilepsy, and currently is also used to relieve neuropathic pain.
Now Scientists at The Scripps Research Institute have found clinical evidence that the drug gabapentin, currently on the market to treat neuropathic pain and epilepsy, helps people to quit smoking marijuana (cannabis). Unlike traditional addiction treatments, gabapentin targets stress systems in the brain that are activated by drug withdrawal.
In a 12-week trial of 50 treatment-seeking cannabis users, those who took gabapentin used less cannabis, experienced fewer withdrawal symptoms such as sleeplessness, and scored higher on tests of attention, impulse-control, and other cognitive skills, compared to patients who received a placebo. If these results are confirmed by ongoing larger trials, gabapentin could become the first FDA-approved pharmaceutical treatment for cannabis dependence.
"A lot of other drugs have been tested for their ability to decrease cannabis use and withdrawal, but this is the first to show these key effects in a controlled treatment study," said Barbara J. Mason, the Pearson Family Chair and Co-Director of the Pearson Center for Alcoholism and Addiction Research at Scripps Research. "The other nice thing about gabapentin is that it is already widely prescribed, so its safety is less likely to be an issue."Ref : http://www.nature.com/npp/journal/vaop/ncurrent/full/npp201214a.html
