zaleplon is one of the "z-drugs", like ambien and lunesta. they are more selective at GABA-a receptors, they affect the hypnotic and amensia parts(the same ones that benzos do) but have little effect on the anti-anxiety and muscle relaxant parts. unlike benzos, z-drugs are only perscribed as hypnotics.
z-drugs are usually very short acting, have more unusual effects like hallucinations, bizarre behavior, and amnesia. they were made to have less abuse potiential than benzos, and they do to a certain extent.
some find z-drugs like zaleplon recreational, but most find benzos better because they are less selective at GABA receptors therefore benzos are more likely going to have better euphoric, relaxing, and anti-anxiety effects.
