Main article: California Proposition 36 (2000)
On November 7, 2000, 60.8% of the state's voters supported an amendment to the statute (offered in Proposition 36) that scaled it back by providing for drug treatment instead of life in prison for most of those convicted of possessing drugs after the amendment went into effect.
