The drug known by the street name Chiva is what?

Chiva is a street name that refers specifically to heroin. Heroin is an opioid drug derived from morphine, which is naturally found in the opium poppy plant. This substance is known for its high potential for addiction and abuse. Users often refer to heroin by various street names, and "Chiva" is one of them, particularly in certain geographic areas or among specific user communities.

The other substances listed—meth, cocaine, and PCP—have their own distinct effects, usage patterns, and street names. Methamphetamine is often referred to as "meth" or "crystal," cocaine is known as "coke" or "snow," and PCP is commonly called "angel dust." Each of these drugs has its unique pharmacological properties and impacts on the user's behavior and health, differentiating them from heroin and from one another. Understanding these distinctions is vital for law enforcement and health professionals in their efforts to address drug-related issues effectively.
