Legal information only. This general explainer is not legal advice.
Start with the federal overlay
State authorization and federal treatment answer different questions. Federal controlled-substance rules can still affect interstate activity, federal property, immigration, firearms, banking, research, and employment.
Then identify the state dimension
Medical access, adult possession, licensed retail, cultivation, product rules, local control, and penalties can change independently. A state described as legal may still prohibit the activity a reader has in mind.
