Birmingham Mayor Randall Woodfin issued blanket pardons for more than 15,000 people with misdemeanor marijuana convictions dating back to 1990.
The pardons from municipal court convictions are automatic.
Woodfin said the pardons would allow people with convictions to rejoin the workforce and provide for their families.
The announcement was made on April 20, a day many associate with marijuana use, and the Alabama Democratic Party said it would support the legalization of marijuana for recreational and medical use in the state.
