Facebook Blocks Ads For Pot Legalization Campaign

Proponents of marijuana legalization, which is on the California ballot in 2010, have hit a Facebook wall in their effort to grow an online campaign to rethink the nation's pot laws. Facebook initially accepted ads from the group Just Say Now, running them from August 7 to August 16, generating 38 million impressions and helping the group's fan page grow to over 6,000 members. But then they were abruptly removed.
