Which item is associated with inhaling powdered cocaine?

Inhaling powdered cocaine, often referred to as "snorting," is commonly facilitated by the use of rolled-up paper tubes. These tubes serve as a conduit for the user to inhale the powdered substance directly into their nasal passages. The structure of the tube allows for easier and more concentrated inhalation, which can lead to a more immediate and intense effect.

While small spoons can be involved in the preparation or measurement of powdered cocaine, and Chore Boy is often associated with smoking crack cocaine, these items do not have the same direct relationship with the act of snorting powdered cocaine as rolled-up paper tubes. Filters are typically not a common accessory when inhaling powdered cocaine since the goal is to introduce the drug directly into the nasal passages without any intermediary substances. Thus, rolled-up paper tubes are the most relevant item in this context.
