When passed, represented 11.8 % 88.2 %. At five years post-RCL implementation, decreased 3.7 %, 24.3 licensed took over 72.0 market. The overall increased size 75 5 years. Illegal between implementation but immediately post-implementation had significant decreasing trend. Medical trend following passage, lesser extent implementation. Total showed increasing time. Some caution should be interpreting findings given uncertainty data quality, particularly (and extension). appears achieving one its primary goals displacing users also appear transitioning recreational However, grown substantially since legalization, which could adverse implications public health.
