Tenn. Code Ann. § 39-17-425 says:
It is unlawful for any person to use, or to possess with intent to use, drug paraphernalia to plant, propagate, cultivate, grow, harvest, manufacture, compound, convert, produce, process, prepare, test, analyze, pack, repack, store, contain, conceal, inject, ingest, inhale, or otherwise introduce into the human body a controlled substance or controlled substance analogue in violation of this part.
This leads to an interesting questions as to what is drug paraphernalia? It is entirely possible you could be in possession of something that police believe to be drug paraphernalia and you never knew it could be used for that.
An officer will use his training and experience to determine if an item is drug paraphernalia. The officer will ask you what the item is used for; look for residue of a controlled substances; look for directions on the item to determine its use.
