What do drug users prefer rubber tubing for during consumption?

Rubber tubing is preferred by drug users during consumption primarily for providing extra tension, which allows for better control and more intense delivery of the substance being used. When rubber tubing is used, it can create a tighter constriction around the vein, enabling the user to locate and access the vein more easily. This additional tension often facilitates the injection process, ensuring that the substance enters the bloodstream quickly and effectively.

The preference for this method is driven by the need for precision and efficiency in the administration of drugs, which can be critical for users seeking immediate effects. While convenience, reusability, and cost efficiency might be aspects of the consumption practice, they are not as directly related to the specific function that rubber tubing serves during the drug consumption process.
