1 This is a rough estimate based on Maine’s numbers. There is a registry, but only a small fraction of California patients are registered.

2 Many families have migrated to Colorado so that patients would be allowed to use medical marijuana, which increases the per capita number of patients.

3 Registry is not open yet.

Washington has a brand new patient registry. The first day for registrations was July 1, 2016.
