The two states have taken slightly different approaches to the rules. Washington’s are slightly more restrictive. There will be limits on the number of sellers’ licenses available there, keeping plants for personal use is not allowed and advertising is restricted to 1,600 square inches (about a meter squared). Colorado, on the other hand, has already begun accepting licenses without a cap, cultivation for personal use is allowed and stores could open as soon as January. Much of the state regulations are set, but the regulatory fight rages on at the local level.
