Which of the following is NOT a street name for depressants?

The correct answer is that "Weed" is not a street name for depressants. In the context of drug nomenclature, "Weed" commonly refers to marijuana, which is classified primarily as a psychoactive substance, specifically a cannabinoid, rather than a depressant.

Depressants, which include substances that slow down the central nervous system, typically have street names that reflect their effects or chemical structure. For instance, "Bars" is a colloquial term for benzodiazepines, "Downers" refers generally to depressants, and "Phennies" is a street name for phenobarbital, which is a barbiturate. These names are associated with the sedative and calming effects that depressants have on a person's mood and behavior. In contrast, "Weed" is about cannabis's stimulating and psychedelics effects, making it entirely different in classification.
