Colorado, Washington Become First States to Legalize Recreational Marijuana

 Colorado and Washington voters have passed referendums on Nov 7,2012 legalizing marijuana for recreational use 

                                                                 

Possession of marijuana is poised to become legal in the US state of Washington, a month after voters opted for decriminalisation.

                                                                        

From midnight (08:00 GMT) anyone aged 21 and over will be allowed to carry up to 1oz (28.4g) of cannabis, but smoking it in public will remain illegal.
It has been legal for medical use in the state since 1998.
Washington and Colorado both voted to decriminalise the drug, which remains illegal under US federal law.
