Mexico drug law may lead the way - TIME

Quietly and with little ado, Mexico last week enacted a law to decriminalize possession of small amounts of all major narcotics, including marijuana, cocaine, heroin, ecstasy and crystal meth. Anyone caught in Mexico with two or three joints or about four lines of cocaine can no longer be arrested, fined or imprisoned. However, police will give them the address of the nearest rehab clinic and advise them to get clean. (from TIME)

"The maximum amount of marijuana 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" (Shown in picture)
