CHANGE: San Francisco will wipe out thousands of marijuana convictions dating to 1975.

San Francisco will retroactively apply California’s new marijuana legalization laws to prior convictions, expunging or reducing misdemeanors and felonies dating to 1975, the district attorney’s office announced Wednesday.

Nearly 5,000 felony marijuana convictions will be reviewed, recalled and resentenced, and more than 3,000 misdemeanors that were sentenced prior to Proposition 64’s passage will be dismissed and sealed, Dist. Atty. George Gascón said. The move will clear people’s records of crimes that can be barriers to employment and housing.

Another barrier to employment is showing up drunk or stoned, but there’s no law or commutation which can help with that.
