Arizona is expected to continue voting on proposition 205 in 2020.

Tim Sultan, executive director of the Arizona Dispensaries Association's ADA, said proposition 205 could be on the table again if the state's marijuana legalization advocates hand over 237,645 valid voter signatures by July 2, 2020

As of January 2020, the Arkansas drug policy education group is collecting competitive signatures for the amendment. After 89,151 valid signatures have been collected by July 3, 2020, the state will vote on the amendment in November 2020.

Since September 2019, marijuana legalization groups in Florida have launched two petitions to legalize recreational marijuana in the state, "Regulate Florida" and "legal Florida."

On December 16, lawmakers in the U.S. state of New Jersey voted to legalize marijuana for adults on the state's November 2020 ballot. The New Jersey senate and legislature both approved the measure by three-fifths votes, and New Jersey's latest polls show broad support for legalization.
By 2020, New Jersey will largely be the next state to legalize marijuana for adults.

On January 6, 2020, the secretary of state of south Dakota officially approved the adult use legalization initiative for the 2020 ballot.
