Gabapentin is a GABA-like drug that has been used medically in the treatment of epilepsy, neuropathic pain, and other conditions.

It has also been used recreationally due to its anxiolytic, sedative, and euphoriant effects.

Even at high strong+ doses, gabapentin is relatively safe physically, but there are still risks and it can certainly cause death.
