This was tried in 2006, but the U.S. objected and it didn’t pass. But now it’s the law
Anyone caught with drug amounts under the personal-use limit will be encouraged to seek treatment, and for those caught a third time treatment is mandatory — although the law does not specify penalties for noncompliance. […]
“This is not legalization, this is regulating the issue and giving citizens greater legal certainty … for a practice that was already in place,” Espino del Castillo said. […]
The maximum amount of marijuana considered to be for “personal use” under the new law is 5 grams — the equivalent of about four joints. The limit is a half gram for cocaine, the equivalent of about 4 “lines.” For other drugs, the limits are 50 milligrams of heroin, 40 milligrams for methamphetamine and 0.015 milligrams for LSD.
This is a useful step, but a very small one. Of course, it won’t have any impact on the cartels or the violence in any way. It is interesting that the U.S. has not seen fit to throw a fit about it.
Update: New York Times headline writer doesn’t get it. Their headline for the AP article: Mexico Legalizes Drug Possession. Um, no. If you’re mandated to attend treatment after being caught the third time with something, it’s not really legal, is it? And possession isn’t even really decriminalized if what you possess happens to be more than 5 grams of pot or more than .015 milligrams of LSD (how do you even measure that?)
