Blitz of pot-legalization ads grows voter support, polls find

A $2.8 million TV advertising blitz in October by the campaign to legalize marijuana appears to have given Initiative 502 a critical boost just as ballots are being cast.

There are no marijuana leaves — or even admitted marijuana users — in the ads, reflecting I-502's strategy to attack the ban on marijuana while not endorsing its use.

The TV spots are made more potent by a lack of opposition ads raising questions about the consequences and costs should Washington become one of the first states to legalize, tax and regulate marijuana like alcohol.
