What item is commonly found in paraphernalia associated with heroin use?

Tin foil is commonly associated with heroin use as it is often used as a surface for smoking the drug. Users may place heroin on a piece of tin foil and heat it from underneath to vaporize the substance, allowing them to inhale the resulting smoke. This method is sometimes referred to as "chasing the dragon." The usage of tin foil highlights a specific method of consumption that is linked to heroin and is a recognizable part of paraphernalia associated with its use.

Plastic bags, while they may be used to contain drugs, are more generic and not exclusive to heroin. Prescription bottles are associated with legally prescribed medications and can be related to various drugs but do not specifically indicate heroin use. Blow pops do not have a connection to drug use and are simply candies, making them irrelevant in this context. Understanding these distinctions helps in identifying specific drug paraphernalia and its implications in substance abuse scenarios.
