The U.S. is in the untenable position of violating the existing treaties — now that four states have legalized the sale of recreational marijuana. The Canadian government announced that it will introduce a bill next spring to decriminalize the sale of marijuana. Mexican leaders announced that their country intends to legalize medical marijuana and loosen restrictions on the amount of drugs people can possess for personal use. These new policies could render the existing drug treaties obsolete. Clearly, those accords need to be updated, heeding the experiences and lessons learned by the nations that have paid the highest price in the drug war.
