Currently, the recreational use of cannabis is legalized in 11 U.S. states (Alaska, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont, and Washington), as well as the District of Columbia, the Northern Mariana Islands, and Guam (see the dedicated wikipedia page).
When will at least 20 U.S. states legalize the recreational use of cannabis?
This question will resolve as the first date when at least 20 U.S. states will have legalized the recreational use of cannabis. Resolution may come from the dedicated wikipedia page, although an admin may need to verify the claims made. If the recreational use of cannabis is legalized at the federal level and effectively decriminalized in at least 20 states, this question also resolves positively.
If this question does not resolve before Oct 6th, 2030, this question will resolve as > October 6, 2030.
