He's actually right; dopamine is our primary pleasure reward system. In addition to interacting with GABA alcohol triggers dopamine in the same way caffeine, amphetamines, and even ecstasy do. And please don't tell me you think Opiates have no effect on dopamine...most drugs just keep dopamine around longer by blocking the reuptake. Opiates literally release the stuff. Hence the massice euphoric state. You have a case with benzos, I suppose but in that case physical addiction is far more prominent than psychological. LSD/halluconigens act on the 5-HT receptors and is not psychologically addictive nor pragmatically possible for physical dependence.
