Professor_Quail notes an AP story that begins, "Mexico enacted a controversial law Thursday decriminalizing possession of small amounts of marijuana, cocaine, heroin and other drugs while encouraging free government treatment for drug dependency. The law sets out maximum 'personal use' amounts for drugs, also including LSD and methamphetamine. People detained with those quantities will no longer face criminal prosecution when the law goes into effect Friday." An official in the attorney general's office said, "This is not legalization, this is regulating the issue and giving citizens greater legal certainty... for a practice that was already in place." In 2006, the US criticized a similar bill that had no provisions for mandatory treatment, and the then-president sent it back to Congress for reconsideration.
