There are critical differences in state medical marijuana laws. The National Conference of State Legislatures (NCSL) has a simple webpage explaining these differences. The differences between federal and state laws are explained. And further down on the page are two tables with each state’s statutes and programs. The first table is called, “state medical marijuana program laws”, and shows whether each state has a patient registry, allows dispensaries, recognizes patients from other states, and if medical marijuana use is allowed for specific conditions. A second table explains the state laws for “limited access marijuana product laws”, with the same table criteria headers as above. Additional resources are provided at the end of the second table.
