Is weed legal in Tennessee?

I'm curious, could you clarify the legal status of weed in Tennessee for me? I've heard conflicting information and I'm wondering if it's actually legal to possess or consume marijuana in the state. Is there a specific law or policy that outlines this? Additionally, are there any penalties or fines associated with breaking this law, and are there any exceptions or allowances for medical use? I'd appreciate any insight you can provide on this topic.
