Where is weed illegal in the US in 2024?

Excuse me, could you please elaborate on the legality of weed, or marijuana, in the United States as of 2024? I'm curious to know which states or territories have not yet legalized its use, possession, or cultivation. Are there any specific regions within the country where weed remains illegal, and if so, what are the penalties for those who violate these laws? Additionally, have there been any recent changes in legislation or proposals that may alter the legal status of weed in the NEAR future? Thank you for your time and assistance in clarifying this matter.
