Leftist politicians in Mexico City have introduced a bill to legalise the sale of marijuana in the nation's capital.
The initiative proposed by members of the Democratic Revolution Party sought to supply marijuana to users and regulate the amount they could buy. It would create a health programme to monitor consumption and sale.
Vidal Llerenas, who proposed the bill, said the objective was to allow authorities to focus on more serious crimes.
Since 2009, Mexico has allowed the possession of 5 grams of marijuana, about four joints, for personal use.
The local proposal was accompanied by an initiative at the federal level, which proposed increasing that amount to 30 grams. The federal proposal also wanted to regulate the cultivation and processing of the plant.
