On November 6, 2012, Colorado Amendment 64 (2012) passed by initiative, legalizing recreational use.
Colorado Amendment 64 is an amendment to the Article 18 of the Colorado state constitution to adopt a progressive cannabis drug policy.
Section 3 will allow the "personal use and regulation of marijuana" for adults 21 and over.
Section 4 addresses legal commercial cultivation, manufacture, and sale.
The intent is that cannabis be regulated in a manner similar to alcohol.[2]
Proposed initiative 2011-2012 #30 was submitted on January 4 and found sufficient by the Secretary of State
on February 27 to appear on the general ballot for November 6, 2012.[1]
The measure passed on November 6, 2012, and along with a similar Washington measure is "an electoral first not only for America but for the world".[3]
