What is a common use of push rods in relation to drug paraphernalia?

Push rods are commonly associated with the manipulation of substances, particularly in the context of drug paraphernalia. They are often used to pack down or manipulate the material, such as in the preparation of marijuana in a pipe or the compacting of substances in other forms of drug consumption. The design of a push rod typically allows for precision when handling materials, making it a practical tool in this context.

While measuring substances, smoking, and injecting substances can also be associated with drug paraphernalia, these activities use different tools or methods. For instance, measuring typically involves scales or measuring cups, smoking usually requires pipes, bongs, or rolling papers, and injecting necessitates syringes. Each of these serves a distinct purpose that does not align with the specific function of a push rod in relation to manipulating substances.
