Lawmakers from Mexico's left-wing Party of the Democratic Revolution (PRD) introduced legislation last week to decriminalize cannabis in an effort to curb cartel violence. One bill, introduced in the federal Congress, builds on the partial decrim passed in 2009, increasing "personal use" quantities from five to 30 grams. It also includes provisions allowing for use of medical marijuana. Another bill in the Federal District's Legislative Assembly would instruct police and judges in Mexico City to deprioritize prosecution of cannabis violations. It would also create "tolerance zones," where cannabis could be sold openly, and "dissuasion commissions" to which violators could be assigned in lieu of criminal charges.
