In what state is weed 100% legal?

I'm curious to know, in which state or territory within the United States is the possession and use of marijuana, commonly referred to as 'weed', fully legalized with no restrictions or penalties? Are there any specific conditions or requirements that need to be met for individuals to legally consume or possess marijuana in this state? Additionally, is there any recent legislation or movements towards further legalization in other states that you are aware of?
