In determining whether an object is an item of drug paraphernalia, a court or other authority, as the case may be, shall consider, in addition to all other logically relevant factors, the following:

1. Statements by an owner or by anyone in control of the object concerning its use;

2. Prior convictions, if any, of an owner, or of anyone in control of the object, under any state or federal law relating to any controlled substance;

3. The proximity of the object, in time and space, to a direct violation of this chapter;

4. The proximity of the object to controlled substances;

5. The existence of any residue of controlled substances on the object;

6. Direct or circumstantial evidence of the intent of any owner, or of anyone in control of the object, to deliver it to persons whom he or she knows, or should reasonably know, intend to use the object to facilitate a violation of this chapter;

7. Instructions, oral or written, provided with the object concerning its use;

8. Descriptive materials accompanying the object which explain or depict its use;

9. National and local advertising concerning its use;

10. The manner in which the object is displayed for sale;

11. Direct or circumstantial evidence of the ratio of sales of the object to the total sales of the business enterprise; and

12. Expert testimony concerning its use.

The innocence of an owner or of anyone in control of the object as to a direct violation of this chapter does not prevent a finding that the object is intended for use or designed for use as an item of drug paraphernalia.
