The state of play
One of the most accessible medical markets in the country, with thousands of licensed dispensaries.
In a medical-only state like Oklahoma, the gatekeeper is the program itself: you need a qualifying condition, a recommendation, and usually a state-issued card before a dispensary will sell to you. Outside that system, the same possession rules apply as in a prohibition state.
Two things trip people up most: assuming a legal purchase elsewhere transfers across state lines (it doesn't — once you cross a border you're under a different rulebook, and possibly federal law), and forgetting that employers, landlords, and federal programs can still set their own rules even where the state says yes.
