What indicates possible heroin use through the presence of paraphernalia that may be found in small bags?

The presence of tiny knotted balloons is a clear indicator of possible heroin use due to the common practices associated with the substance's distribution and consumption. Heroin is often packaged in small, discrete quantities, and users or dealers frequently use balloons to hold the drug. This method of packaging allows for easy transport and reduces the risk of detection by law enforcement.

Balloons, when knotted, indicate not only the packaging of the drug but also suggest an owner's intent to maintain its integrity and concealment. In many cases, users will use these balloons to either inject the heroin or as a method for oral consumption, further linking this paraphernalia choice specifically to heroin use.

While glass containers, pill bottles, and papers can be associated with various kinds of drug use, they lack the direct, distinct connection to heroin like tiny knotted balloons do. Glass containers could hold many substances, pill bottles may indicate prescription drug use, and papers might refer to rolling materials for cannabis or other drugs. Therefore, when assessing paraphernalia indicative of heroin, tiny knotted balloons stand out as a specific marker of heroin usage.
