Is a barbiturate an opiate

The DEA classes only opium, opium derivatives, and synthetic opioids, along with cocaine and coca leaves as narcotics.

In general conversation, barbiturates are often lumped together with other drugs of abuse under the (inaccurate) label. Barbiturates are central nervous system depressants, and share some common effects with narcotics. They are not technically narcotics, but hypnotics or sedatives.
