SB 649 (Leno) will allow prosecuting simple possession of certain controlled substances, including, among others, opiates, opium, opium derivatives, mescaline, peyote, tetrahydrocannabinols (marijuana), and cocaine base, as "wobblers", that is, either as felonies or as misdemeanors. SB 649 has just cleared the assembly floor, 41-30, and it's on the way to Gov. Brown via a Senate approval of the amendments.
This is very good news to those who would like to see the end of the war on drugs, and who think that nonviolent drug offenders are being punished too harshly.
UPDATE (Sep. 10, 2013): The bill has now passed the Senate floor as amended and is on its way to the Governor for signatures.
