Question

Quizplus · Accepted Answer

Opiates are a group of drugs that mimic the effects of endorphins and occupy endorphin receptor sites in the brain. They were first discovered centuries ago, not in the 1960s. Seconal and Nembutal are not opiates, they are barbiturates. Opiates are not chemically almost identical to serotonin, they are a distinct group of drugs that act on the brain in specific ways.
