Neo-Dove is the nickname of the drug 4-floroamphetamine, or 4-FA. 4-FA is an amphetamine that causes euphoria, empathy, and very mild hallucinations similar to MDMA (Ecstasy.) It also has similar stimulant effects as other amphetamine class drugs.
I did 200mg of Neo-Dove last night at a party. Felt like I was rolling for about 6 hours.
