Gabapentin is an anti-epileptic drug, also called an anticonvulsant. It affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain. Gabapentin is used in adults to treat neuropathic pain (nerve pain) caused by herpes virus or shingles (herpes zoster).
Gabapentin can produce feelings of relaxation, calmness and euphoria. Some users have reported that the high from snorted gabapentin can be similar to taking a stimulant. It can also enhance the euphoric effects of other drugs, like opiates, and is likely to increase the risks when taken in this way.
